Polaris Dawn astronauts will undergo brain MRIs upon landing

The scans will be conducted earlier than any other post-flight imaging of astronauts on record. 

CT scans highlight impact of semaglutide on body composition

Body composition metrics derived from CT scans provide greater insight into how losing weight affects the body from a cardiometabolic perspective.

Breast arterial calcifications (BACs) identified on screening mammograms may help identify women who face a heightened risk of developing cardiovascular disease (CVD), according to a new analysis published in Clinical Imaging.

Nearly 25% of women with breast arterial calcifications on mammo develop heart disease

Specifically, women with BACs on their mammogram may be at an increased risk of atherosclerotic cardiovascular disease.

Some people may be predisposed to depression, MRI study shows

Specific brain connectivity patterns evident during childhood might make people more vulnerable to developing psychiatric disorders.

OCT-guided PCI, or optical coherence tomography-guided percutaneous coronary intervention.

OCT-guided PCI boosts outcomes when treating complex lesions

When PCI patients present with complex lesions, optical coherence tomography may provide significant value.

Both diabetes and prediabetes accelerate brain aging, MRI analysis shows

The less control a person has over their diabetes, the greater the difference between chronological age and estimated brain age based on MRI markers, according to the study.

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.

The newly cleared offering, AutoChamber, was designed with opportunistic screening in mind. It can evaluate many different kinds of CT images, including those originally gathered to screen patients for lung cancer.
