Patient with Brain Infarction. Diffusion weighted imaging (DWI) is a commonly performed MRI sequence for evaluation of acute ischemic stroke, and is sensitive in the detection of small and early infarcts. Conventional MRI sequences (eg FLAIR) may not demonstrate an infarct for 6 hours, and small infarcts may be hard to estimate on CT for days.
High resolution Magnetic Resonance Neurography (MRN) of the Brachial Plexus, based on Coronal and Axial 2D STIR Acquisitions and Axial 2D T2-W Acquisition. Newer techniques like 3D STIR, 3D DIR or 3D NerveVIEW were not available (Image dataset acquired in an old 1.5T scanner). The brachial plexus is a complex network of nerves formed by the anterior rami of the lower four cervical nerves (C5, C6, C7, C8) and first thoracic nerve (T1), which supplies motor and sensory innervation to the upper limb and pectoral girdle. MRN is a non-invasive imaging technique for the dedicated assessment of peripheral nerves. Because of its excellent soft-tissue contrast, MRN offers anatomical information that is not obtainable with other modalities.

Hemispherectomy is a very rare neurosurgical procedure in which a cerebral hemisphere (half of the brain) is removed, disconnected, or disabled. This procedure is used to treat a variety of seizure disorders where the source of the epilepsy is localized to a broad area of a single hemisphere of the brain, notably Rasmussen's encephalitis. About one in three patients with epilepsy will continue to have persistent seizures despite epileptic drug therapy. Hemispherectomy is reserved for the most extreme cases of this one-third in which the individual’s seizures are irresponsive to medications or other less invasive surgeries and significantly impair functioning or put the patient at risk of further complications. The procedure successfully cures seizures in about 85–90% of patients. Image courtesy of Dorit Kliemann et al. (DOI:

MR Imaging of the Spine on a Patient with Scoliosis. Scoliosis is a sideways curvature of the spine that occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such as cerebral palsy and muscular dystrophy, the cause of most scoliosis is unknown. About 3% of adolescents have scoliosis. Most cases of scoliosis are mild, but some spine deformities continue to get more severe as children grow.
Agenesis of the Corpus callosum (ACC). It is a rare birth defect (congenital disorder) in which there is a complete or partial absence of the corpus callosum. It occurs when the corpus callosum fails to develop normally, typically during pregnancy. The fibers that would otherwise form the corpus callosum become longitudinally oriented along the ipsilateral ventricular wall and form structures called Probst bundles.
Sagittal T2-weighted MR image of the Brain. Variant Dandy–Walker Syndrome (DWS) with Dysplasia of the Pons and Cerebellum in an 8-year old. DWS is a rare group of congenital human brain malformations. There are three subtypes which affect multiple organs to varying degrees, but the fundamental abnormalities involve the cerebellum which controls muscle coordination. The adjacent third and fourth ventricles are often affected, which can alter the flow of cerebrospinal fluid, increase intracranial pressure and lead to multiple other brain function problems.

The Right Hemisphere is a 3D reconstruction from Structural 3T Magnetic Resonance Imaging (MRI) Data (pink), while in the Left Hemisphere, Nerve fibres have been visualised using Diffusion Imaging Tractography (multi-coloured). Diffusion tensor imaging (DTI) is a specialised type of magnetic resonance imaging (MRI) scan which measures water diffusion in many directions in order to reconstruct the orientation of bundles of axons. Tractography is used to indirectly model these bundles of axons (nerve fibres), which transmit information between cortical regions at the brain's surface. Credit: Gabriel González-Escamilla
Patient with Arteriovenous malformation (AVM). AVM is an abnormal connection between arteries and veins, bypassing the capillary system.
SWI Contrast in MRI. SWI is a new type of contrast in MRI which exploits the susceptibility differences between tissues. As a result SWI detects substances with different susceptibilities than their neighboring tissues such as deoxygenated blood, products of blood decomposition and microscopic iron deposits much better than conventional "hemo" MR techniques. Among other things, the method allows for highly sensitive proof of cerebral hemorrhage and high resolution display of venous cerebral vessels.

MR Imaging of the Brain in a Patient with Glioblastoma Multiforme (GBM). High resolution anatomical sequences (volumetric T2, volumetric FLAIR, volumetric T1), 3D SWAN (for hemorrhage and vasculature assessment) and functional-quantitative sequences (DWI and PWI) was used. GBM (also called glioblastoma) is a fast-growing glioma that develops from star-shaped glial cells (astrocytes and oligodendrocytes) that support the health of the nerve cells within the brain. These are the most invasive type of glial tumors, rapidly growing and commonly spreading into nearby brain tissue. In adults, GBM occurs most often in the cerebral hemispheres, especially in the frontal and temporal lobes of the brain.
MR diffusion-weighted imaging (DWI) in monitoring the response to treatment in Cervical Cancers. DWI shows that there is an increase in tumor's diffusivity (the ADC value before radiotherapy was 603 μm2/sec, and the ADC value after radiotherapy is 917 μm2/sec) and a decrease in tumor's volume after the radiotherapy. These changes in tumor's microarchitecture are not initially seen using conventional anatomical imaging.

Patient with elevated PSA and a very suspicious area in the transition zone with low signal on T2-w, diffusion restriction and high perfusion and permeability, as indicated by the quantitative analysis of DCE-MRI data. The role of Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) for tumour diagnosis and assessment in the current version of PI-RADS (version 2) is minimized. DCE-MRI is only considered when DWI in the peripheral zone (PZ) is indeterminate. Although, DCE Perfusion has shown potential in prostate cancer detection, localization and staging, assessment of tumour aggressiveness and assessment of treatment response. Note that ktrans is the influx mass transfer rate of gadolinium (ktrans depends on blood flow, capillary surface area, and capillary permeability), and kep is the corresponding efflux rate of gadolinium from the extravascular-extracellular space (EES) back into plasma.

Magnetic Resonance Enterography (MRE). Figure shows a T2-Weighted Single-Shot Fast Spin Echo/SS-FSE (left) and a Volume-interpolated 3D T1-w GRE DIXON (right). Oral contrast agents must be used in MRE. Oral contrast agents used for MRE can be categorized as positive, negative, and biphasic (figure) contrast agents. The most commonly used MRE contrast agents are biphasic, exhibiting high signal intensity on T2-w imaging (allowing for detection of wall thickening, endoluminal abnormalities, and transmural ulcers) and low signal intensity on T1-w imaging (enhancing detection of mucosal enhancement and hypervascular endoluminal masses).

Magnetic resonance cholangiopancreatography (MRCP) Image. MRCP is a medical imaging technique that uses magnetic resonance imaging to visualize the biliary and pancreatic ducts in a non-invasive manner. MRCP makes use of heavily T2-weighted MRI pulse sequences. These sequences show high signal in static or slow moving fluids within the gallbladder, biliary ducts and pancreatic duct, with low signal of surrounding tissue. In the diagnosis of pancreatic disorders, MRCP is a much less invasive investigation when compared to endoscopic retrograde cholangiopancreatography (ERCP). Although both techniques can image the ductal system in detail, MRCP also allows imaging of the surrounding parenchyma.

Figure shows the same 2D T2-w FS FSE acquisition. 3 NEX and respiratory triggering was used in the image to the left, while 1 NEX and breath holding technique was used in the image to the right. Note that the metastasis can clearly be seen only in the image to the left. The number of excitations (NEX or NSA or averages) is used to represent the number of times each line of k-space data is acquired and is primarily used to improve the signal-to-noise ratio (SNR). However, because the contrast-to-noise ratio (CNR) is controlled by the same factors that affect SNR, keep always in mind that NEX also affects the image CNR, as shown by this figure.

Whole-body magnetic resonance imaging (WB-MRI) has been available for some time, but only recently it has become an efficient method for total body screening from head to toes. In clinical practice, WB-MRI is increasingly being used in the diagnosis of a variety of diseases, including lymphomas, multiple myeloma, systemic musculoskeletal diseases, and also systemic diseases like diabetes and atherosclerosis. Furthermore, WB-MRI is very useful in children with malignant diseases (and other pathologies) due to the use of non ionising radiation. Improvements of the software and hardware, multiplanar imaging capabilities, high contrast resolution, anatomical and functional imaging make MRI a great alternative for whole body screening within clinically acceptable acquisition times.

Comprehensive, Multiparametric (anatomical and functional) MR Imaging of the Gynecological Organs on a big patient with Non-Keratinizing Squamous Cell Carcinoma of the Cervix. Multiparametric gynecological organs protocol consists of high resolution T2-w acquisitions (at least in two imaging planes), diffusion-weighted imaging (low, intermediate and high b values are needed) with corresponding ADC map, dynamic contrast-enhanced perfusion-weighted imaging (DCE PWI), and pre- and post-contrast T1-w acquisitions.
High resolution MR Imaging of the Cirrhotic Liver at 1.5 Tesla. Cirrhosis is scarring of the liver caused by long-term liver damage. The scar tissue prevents the liver working properly. Cirrhosis can eventually lead to liver failure, where the liver stops working, which can be fatal. Unfortunately, conventional MRI is insensitive in early cirrhosis, and its role is in screening cirrhotic livers for small HCCs. LiverMultiScan (Perspectum Diagnostics patented technology) can assist in the detection of early liver disease and predict the outcomes in patients with chronic liver disease. More info about Perspectum and LiverMultiScan here: Images courtesy of Christos Tsiotsios.

MRI of the Prostate Gland: Multiparametric Prostate MRI MRI of the Prostate Gland was first described in the mid-1980s with early publications describing the sub-structure visualization and characterization using T2-w imaging. Even with the low spatial resolution attained with the medium-field magnets and body coil technology employed at the time, it was immediately evident that MR could provide a unique and novel approach to imaging diseases of the prostate. The endorectal coil, also introduced in the mid-to-late 1980s, added significantly to the quality of prostate MRI by enhancing visualization of sub-glandular structures. In the last decade, Multiparametric Prostate MRI (which essentially combines anatomical and functional data) has seen a major increase in interest in the detection and characterization of focal prostate cancer with exciting developments in diffusion-weighted imaging (DWI) and dynamic contrast-enhanced perfusion-weighted imaging (DCE PWI), techniques that show promise in allowing for better assessment of prostate cancer aggressiveness through correlation with low, intermediate, and high Gleason scores.

High Resolution MR Imaging of the Breast in a Patient with Invasive Carcinoma of no special type (NST). Multiparametric MRI (anatomical and functional) can greatly help in tumour staging.
Hyperpolarised Gas Ventilation Imaging: MRI Lung imaging with hyperpolarised gases and proton MRI which provide very detailed images of patient’s lungs without relying on X-rays radiation. The technique of hyperpolarised gas MRI involves a person inhaling small amounts of noble gases (Helium-3 and Xenon-129), which are then imaged inside an MRI scanner. The gases are hyperpolarised using high power lasers by a process called optical pumping. The group have developed specialised gas laser polarisers and custom MRI scanner hardware which provide high-resolution images that are not currently available with conventional methods. The innovative imaging technology illuminates lung function and helps clinicians identify early signs of lung disease, for example earlier diagnosis of emphysema and smoking related damage, as well as other lung conditions and diseases such as pulmonary fibrosis, asthma, pulmonary hypertension and cystic fibrosis.
Comprehensive, Multiparametric (anatomical, functional and pharmacokinetic) MR Imaging of the Breast on a Patient with Breast cancer. The lesion shows enhancement kinetic curve type III (fast contrast uptake/wash-in and wash-out), diffusion restriction and irregular borders. Breast cancer is the most common cancer in women. On a global scale, every tenth woman is affected, and numbers continue to rise. MR imaging can help provide early and reliable diagnosis especially in difficult cases. It can support accurate preoperative staging and differential diagnosis, resulting in faster and more cost-effective patient management.

Magnetic Resonance (MR) Arthrography was first introduced to the musculoskeletal community in 1987 with a cadaveric study of several joints including the shoulder. Today, MR Arthrography is widely utilized and considered by most musculoskeletal radiologists and orthopedists to be an integral part of their clinical practice. MR Arthrography of the shoulder has proven to be the gold standard imaging technique for evaluation of shoulder joint pathology and can be particularly useful for evaluation of labroligamentous abnormalities. The advantages of MR Arthrography are particularly evident when evaluating acute pathology in younger, active patients with relatively little degenerative joint disease.

Playing with K-Space. Signal, contrast and resolution information in K-space. If we erase the middle of K-space and just reconstruct the peripheral/outside data (bottom left) we can see where the tissue boundaries are, but the signal-to-noise ratio (SNR) is low and we have no contrast information. From the other side, by reconstructing only the data from the middle of K-space (bottom right) we get all the signal and contrast information, but it is very blurred. Clearly we need both parts of K-space to get a useful MR image.This image has been reconstructed by the application “2D-Fourier".

44-year-old woman with knee pain after injury. MRI shows a PCL tear (blue arrows). The Posterior Cruciate Ligament (PCL) is a ligament within the knee. Although it is larger and stronger than the ACL, the PCL can be torn. PCL tears make up less than 20% of injuries to knee ligaments. Injuries that tear the PCL often damage some of the other ligaments or cartilage in the knee, as well.
Temporomandibular joints (TMJs) abnormalities cannot be reliably assessed by a clinical examination. Magnetic Resonance Imaging (MRI) may depict joint abnormalities not seen with any other imaging method and thus is the best method to make a diagnostic assessment of the TMJs status. Proton-density weighted (PD-w) images with and without fat suppression highlight the disc well as a hypointense biconcave structure between the condyle and articular eminence. Post-contrast T1-w imaging can be helpful in evaluating inflammatory arthritis by allowing the distinction of pannus formation from effusion.

Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. MRA is used to generate images of arteries and veins in order to evaluate them for stenosis, occlusions, aneurysms or other abnormalities. MRA is often used to evaluate the arteries of the neck and brain, the thoracic and abdominal aorta, the renal arteries, and the legs (the latter exam is often referred to as a "run-off").
Whole body MR Angiography demonstrates the main arteries of the human body.
Non-contrast enhanced Magnetic Resonance Angiography (NCE-MRA) of the Renal Arteries in a Patient with Renal Mass. Image dataset acquired at 1.5T, using Inhance Inflow IR (IFIR) sequence (GE's version for Inflow balanced-SSFP with IR Saturation). The relative high signal of arterial blood on balanced SSFP sequences (eg FIESTA, True-FISP) can be further accentuated by exploiting inflow-related enhancement similar to that used in time-of-flight MRA. The area of interest is first saturated with one or more 180°-RF pulses. These saturation pulses invert signal from background tissue as well as venous blood. "Fresh" (unsaturated/fully magnetized) arterial blood next flows into the slab.

High resolution, Contrast-Enhanced Magnetic Resonance Angiography (CE-MRA) of the Thoracic Aorta. Imaging plays a key role in the clinical evaluation of aortic pathology. MRI is a versatile modality in this setting, providing precise information about aortic anatomy and pathology. The technique most commonly used to image the lumen is CE-MRA. With this method, a gadolinium-based contrast material is injected into a peripheral vein (typically an antecubital vein). Image acquisition occurs when the contrast reaches the arterial system for the first time (first-pass circulation) after circulating through the right heart chambers, pulmonary circulation, and left heart chambers. A 3D Spoiled T1-weighted GRE sequence is used for acquisition, yielding good contrast between the thoracic aorta and the veins and background tissues. Images are acquired during breath holds, typically of approximately 10-20 seconds.
High resolution, Contrast-Enhanced Magnetic Resonance Angiography (CE-MRA) of the Thoracic and Abdominal Aorta. MRA is performed without the use of ionizing radiation or iodinated contrast material. Using MRA, the clinician can visualize the aorta and major branches in multiple 3D projections.
