Get That Blood Flowing!
Vascular imaging is a significant part of MRI. The ability to image vessels in our patients using non-ionizing means and/or non-ionizing radiation is quite…appealing! There are also techniques; within vascular imaging, that do not require the use of contrast media.
The Time-of-Flight (TOF) MRA is a great tool for visualing vessels in areas where our patients can hold still for an extended period of time.
TOF MRA involves both 2D and 3D imaging. Both have their; individual, benefits and limits.
Phase contrast MRA/ PC – MRA can be utilized for background suppression of tissues. It provides us with coherent and intricate images as well as additional data that we can work with. The issue; however, is that it can contribute to longer acquisition times and/or inaccurate VENC.
The Contrast-Enhanced MRA and/or CE-MRA is a tool that requires us to utilize contrast media. However; this type of MRA, can help us obtain better images and/or images with fewer technical inaccuracies.
