Virtual colonoscopy payments climb slowly
By Marty Graham

Pediatric pneumothorax volume measurement system developed
By Cynthia E. Keen
Diagnosing a pneumothorax in a pediatric patient and assessing its size are important for proper clinical management, especially in determining the need for chest-tube drainage. MDCT scans make diagnosis easier, but manually contouring identified pneumothoraces to determine their size can take hours to perform.

Ascending colon rotation can mask colonic polyps
By Eric Barnes
Polyps in the ascending colon can mimic mobile contents such as fecal matter when patients turn from prone to supine position at virtual colonoscopy, potentially skewing interpretation, a new study indicates. Simple awareness of the phenomenon can go a long way toward helping radiologists avoid misinterpretation of virtual colonoscopy results.
