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

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

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

Comparison of a 2D digital mammogram and breast tomosynthesis 3D mammography showing ability to better evaluate details in areas of dense breast tissue, rather than seeing areas of dense breast tissue overlapping, which can mimic or hide a cancer. Photo from UCSF.

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. 

Philips celebrates nearly 2M liters of liquid helium saved thanks to its helium-free MRI technology

RSNA attendee tries out the new Philips 5300 MRI system video viewing system (projected on the wall behind the MRI and viewed using a mirror) to entertain patients during longer exams. The system is a "helium free" system. It has a sealed cooling system so it only uses 7 liters of helium, as opposed to the usual 1,500 liters in conventional MRI systems.
