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.

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.
