Trauma Pod brings robotic ICU to the battlefield
An unmanned mobile ICU called Trauma Pod, complete with a CT scanner, may one day be treating wounded soldiers in remote battlefields. The U.S. Department of Defense is currently developing this high-tech robotic surgical unit with a consortium of 12 firms, with the first phase of the project based on existing technologies. Click on the videos to glimpse the future -- and the present -- of robotic surgery.

MDCT edges MRI in characterizing kidney lesions
MDCT did a little better than MRI in the task of characterizing kidney lesions in a new study by German researchers, but both modalities were only mediocre in differentiating benign from malignant lesions.

Lung CAD may lead radiologists down the wrong path
SAN FRANCISCO - One thing seems certain as lung computer-aided detection (CAD) systems move increasingly into clinical use: radiologists find more potentially malignant nodules with CAD than without it. But could CAD also be a case of too much of a good thing?

VC software highlights colon's unseen areas
A new virtual colonoscopy software application aims to eliminate the problem of missed areas on endoluminal fly-throughs by highlighting spots that were missed during the first two fly-throughs, so they can be examined in a third look. A video clip shows you how it's done.

Dual-source imaging promises better CT scanning
SAN FRANCISCO - Dual-source CT (DSCT) promises big gains -- principally in terms of speed and power -- for imaging applications that have traditionally been starved for one or both, according to presentations at this week's International Symposium on Multidetector-Row CT.

Flat polyps foil readers in 16-slice VC study
Korean researchers had a hard time finding flat polyps on contrast-enhanced virtual colonoscopy, even with the aid of thin-section imaging on a 16-slice CT scanner, according to a new study. Fewer than half of the flat lesions in the retrospective patient cohort were detected by blinded and unblinded review together.

VC finds risky polyps, might reduce polypectomies
A sizable study lends new weight to the argument that virtual colonoscopy finds the riskiest colorectal polyps by nailing the largest ones. The results suggest that if VC surveillance were substituted for colonoscopy, some polypectomies of smaller lesions could be safely eliminated.

Adaptive trigger delay compensates for motion in cardiac MR
The heart has resisted attempts to image it crisply in every modality. Cardiac MRI in particular has struggled with the effects of cardiac motion. But now a new study proposes an adaptive trigger delay method to compensate for beat-to-beat variations in coronary motion.

AI model generates x-ray reports similar to radiologists
By Will Morton
A team at Northwestern University has developed an AI model that could serve to alert physicians to life-threatening diseases on chest x-rays.
October 5, 2023
The AI model is an encoder-decoder model trained to generate a text report given a chest x-ray and most recent comparison (anterior-posterior or posterior-anterior view only). The vision encoder weights were initialized from Vision Transformer (ViT) base and the text decoder weights were initialized from Robustly Optimized BERT Pretraining Approach (RoBERTa) base before training for 30 epochs on a data set of 900,000 chest x-rays (CXRs). cp indicates chest pain; sob = shortness of breath.
