Diversity in interventional radiology residency programs lacking
Interventional radiology is one of the least diverse medical specialties among residents, a new analysis found.
Velocity streamlines of the portal vein measured using 4D flow MRI in a cirrhosis patient (a 62-year-old male), shown at the cardiac cycle time t = 84 ms. A cut-plane (white marker) matching the 2D flow image plane was used to quantify the 4D flow parameters in the main portal vein.
