Ron Blankstein, MD, Brigham and Womens Hospital, explains a study using AI opportunistic screening in non-cardiac CT scans looking for coronary artery disease.

Use of AI opportunistic screening in CT for cardiovascular disease

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.

Mayo AI algorithm uses 3D body scans to predict risk of metabolic syndrome.

AI tool predicts metabolic disease using 3D body scans

Compared to standard hip-to-waist ratio measurements and BMI, the algorithm identifies significantly more instances of metabolic syndrome and its severity in individual patients.

GBCA doses can be reduced by over 50% for some MRI exams

In some cases, contrast doses can be reduced by as much as 62% without sacrificing diagnostic quality.

Radiology's role in colorectal cancer care set to grow following 'groundbreaking' trial results

The results were so conclusive that the trial was halted at halftime for having met predefined stopping rules. 

Lung cancer screening CT image in a 66-year-old male patient shows a sessile nodule with internal air in the left mainstem to left upper lobe bronchus (arrow) with a mean diameter of 10 mm. The nodule was assigned as Lung-RADS category 4A in the clinical report. (B) Follow-up CT image shows the lesion is resolved. Image courtesy of RSNA

Lung-RADS update helps limit false-positive results, unnecessary procedures

Using the latest version was associated with improved diagnostic accuracy, researchers wrote in a new analysis. 

Comparison of a 2D digital mammogram and breast tomosynthesis 3D mammography from UCSF.

DBT exams take twice as long to read as 2D mammograms, but the learning curve is short

Although DBT exams are proven to identify more difficult to detect cancers, especially among women with dense breasts, they also include significantly more images than standard 2D mammograms.

Interval breast cancer has its own risk factors, mortality patterns

Women with dense breast tissue are less likely than normal-density peers to develop breast cancer between screening mammography exams.

Biopsy before ablation has no cost advantage over both-at-once approach

Established guidelines recommend biopsying small tumors of the kidney ahead of any procedure to ablate them. A new study confirms the validity of pursuing another pathway.

Around the web

After reviewing years of data from its clinic, one institution discovered that issues with implant data integrity frequently put patients at risk. 

Prior to the final proposal’s release, the American College of Radiology reached out to CMS to offer its recommendations on payment rates for five out of the six the new codes.

“Before these CPT codes there was no real acknowledgment of the additional burden borne by the providers who accepted these patients."
