In This Episode, Reggie and Robert talk about different MR Angiography techniques, with guest Matthew Hayes RT(R)(MR), Creator and President, ScanLabMR, and Professor of MRI, Adventist University of Health Sciences. Matthew opens by explaining the Time of Flight (TOF), and the pros and cons of each 2D and 3D Technique. Then explains contrast enhancement techniques and the importance of understanding Time to Center (TTC). He also shares a few tricks to help with missing the bolus. To wrap up, Matthew breaks down, Time Resolve, Phase Contrast, Velocity encoding (Venc), and the difference between Visualization and Quantification.

Aegys is committed to providing innovative product and process solutions that enhance overall magnet safety and improve efficiency. TechGate Auto is a Zone 4 Barrier System that keeps patients and MRI technologists safe. TechGate Auto allows technologists to focus on the care of patients and efficient room turnaround rather than worrying about anyone entering the MRI room behind them. Easy to use and designed for the MRI environment, TechGate Auto is deployed whenever the technologist enters or leaves the MR room or via push button remote control, providing an immediate physical restriction of access to all unauthorized individuals. The use of a “caution” barrier at the entrance to the MR room is now a recommendation of the American College of Radiology MR Safety Committee.

He received subpar training on more than one occasion after new MRI installations. With the goal to remedy this, he started being more active in sharing his knowledge on scanner utilization starting in 2011 after attending a conference by Dr. Kanal. Over years he was exposed to different vendors and learned the systems to become a superuser. He then shared that knowledge with his peers. This passion later became a business that welcomes application specialists and knowledgeable users that want to share their expertise and get paid to do it.
