Imaging Contrast

Contrast agents are injected into patients to help enhance images to make it easier for radiologists distinguish specific areas of the body from surrounding tissues. The most commonly used agents are iodinated contrast dye for computed tomography (CT), interventional cath lab angiography,  RF fluoroscopy, and in surgical OR procedures. MRI scans typically use gadolinium-based contrast agents. Ultrasound and echocardiography (cardiac ultrasound) imaging use contrast agents composed of microscopic bubbles to enhance images that otherwise would be suboptimal.

Photon counting cuts CTA contrast dosage 25%

Not only does the low-volume contrast protocol preserve supplies, it also protects patients who might be vulnerable to adverse reactions and/or side effects from contrast use.

Contrast-enhanced mammography uses iodine contrast injected into a patient and mammography system to image contrast uptake or areas of increased vascular activity, which is typical of cancers. This can help image through dense breast tissue to find cancers that are otherwise masked by dense breast tissue.

Radiologists should be aware of these clinical factors when reading CEM scans

The degree of background parenchymal enhancement on CEM during certain days of a premenopausal woman's cycle could impact how radiologists interpret the exam.

GE Healthcare program recycles departments' leftover iodinated contrast for future use

In 2006, the company started an iodine recycling program for imaging departments that had leftover contrast that would go to waste at the end of the day if left unused. That program expanded into the U.S. and Canada in 2021.
