Cross-organ imaging illuminates the heart-brain-liver axis

A population-level study featuring multi-organ MRI has confirmed that problems in any of three major organs—the heart, brain or liver—tend to co-occur with unfavorable findings in either or both of the other two.

Urinary stones in the ED: What will it take for ultrasound to gain ground on costly, radiative CT?

Professional consensus supports the use of ultrasound for initial imaging evaluation of patients presenting in the ED with suspected urinary stone disease (USD). However, as of 2018, only 2% of these patients received ultrasound while some 59% had CT.

Sean Fain, PhD, vice chair of radiology and research and a professor of radiology, Division of Cardiovascular and Thoracic Imaging, University of Iowa, discusses how long-COVID lung damage can be tracked using xenon (Xe) gas magnetic resonance imaging (MRI) and quantitative computed tomography (CT). He spoke to Health Imaging at RSNA 2022.

On its own, MRI-targeted biopsy takes big bite out of prostate cancer overdiagnosis

The gain came with the delayed discovery of only a few clinically significant cancers.

Cancer patients unruffled by whole-body MRI per se

Claustrophobic or not, most would choose the radiation-free modality over CT and tend to consider imaging-exam outcomes more worrisome than MRI in and of itself anyway.
