Interventional Imaging

A subspecialty of interventional radiology (IR) uses image-guided, minimally-invasive procedures to diagnose and treat various diseases. Interventional radiologists rely on angiography, mobile C-arm and fluoroscopy imaging systems to perform thrombolysis, embolization, biopsies, vascular and other minimally invasive procedures, which can reduce recovery time, risk and costs.

A comparison between a traditional iodine contrast angiogram (left), and a gadolinium contrast angiogram (right). MRI gadolinium contrast is starting to be used in some interventional radiology procedures and is being considered in interventional cardiology due to the iodine contrast shortage.

Gadolinium can be used as substitute for iodine contrast in some interventional imaging procedures

Gadolinium might be an alternative, stop-gap solution for interventional procedures during the current iodine contrast shortage.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
