Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

New atherosclerosis treatment uses ultrasound-assisted lasers to break down plaque

The new technique is still in the development stage, but early research suggests it could provide clinicians with a new treatment option for breaking down arterial plaque.

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.

A medical professional trained to manage contrast reactions should be on-site at any imaging facilities doing contrast studies to maintain patient safety, according to a an updated statement from the American College of Radiology. The ACR has released the latest edition of the ACR Appropriateness Criteria, which includes 221 diagnostic imaging and interventional radiology topics with more than 1,050 clinical variants covering 2,900 clinical scenarios. #ACR #AUC #appropriateuse

Addressing contrast media shortage in the short, mid and long term

“We need to commit to changing the supply chain so that a single event in a faraway country does not put us in this predicament again," experts wrote in a new special report shared by Radiology.
