US technology images blood flow to breast, kidney tissue
By AuntMinnie.com staff writers
California start-up Sensant of San Leandro unveiled clinical images of micro-vessel blood flow inside breast and kidney tissue at this year’s RSNA show. The images were generated with Sensant’s new ultrasound probe technology, Silicon Ultrasound, which uses silicon-based transducers rather than conventional piezoelectric, crystal-based probes, along with the SonoVue ultrasound contrast agent from Esaote of Genoa, Italy. Silicon Ultrasound technology is based on work performed at Stanford University on capacitive microfabricated ultrasonic transducers (cMUTs).

PET/CT shows promise as first-line tool for oncologic staging, topping MRI in one head-to-head comparison
By Jonathan S. Batchelor
CHICAGO - Accurate tumor staging is critical for patient management in clinical oncology. Research conducted by a team from Essen, Germany, suggests stage-adapted therapy – tumor staging (T), lymph node metastasis staging (N), and distant metastasis staging (M) – may benefit by the use of a mix of modalities.

Imaging helps detect and treat bariatric surgery complications
By Paula Moyer
CHICAGO - In a cruel twist of irony, obesity itself places the only patients who would undergo bariatric surgery at increased risk of perioperative and postoperative complications. However, radiologists can enhance the safety of both the surgery and the convalescence, according to a presentation at the 2003 RSNA meeting.

International committee of CT users and vendors settles on mass as the standard measurement of coronary calcium
By Eric Barnes
CHICAGO - The Agatston score has officially been replaced by calcium mass for coronary artery calcium assessment. It has, at least, in the eyes of an international consortium of radiologists, physicists, and vendors that has labored for four years to settle on a new standard designed to work as well for electron-beam CT (EBCT) scanners as it does for multidetector-row CT (MDCT) machines.
