Cardiac MRI tracks impact of statin therapy on plaque
By Brian Casey
NEW ORLEANS - Cardiac MRI can be used as a tool to assess the impact of statin therapy in reducing atherosclerotic plaque, possibly earlier than other modalities, according to a paper presented at the American College of Cardiology meeting this week.

Resting MCE may prove superior to SPECT for identifying myocardial viability
By Jerry Ingram
NEW ORLEANS - Resting myocardial contrast echocardiography (MCE), a new bedside procedure that can determine microvascular perfusion, might one day replace 99mTechnetium sestamibi SPECT for the diagnosis of myocardial viability following acute myocardial infarction, according to a poster presented today at the American College of Cardiology (ACC) meeting.

Ultrasound aces search for ureteral stones
By Eric Barnes
VIENNA - Ultrasound is considered to be a rather challenging modality for detecting ureteral stones, but it worked like a charm for Drs. Jongmin Kim and S. H. Kim from the Jinju Gospel Hospital in Jinju, South Korea. Ultrasound left no stone unfound in the team’s eight-month study of emergency-room patients, as confirmed in follow-up imaging studies and clinical interventions.

MDCT reliably gauges vascular infiltration in pancreatic cancer
By Eric Barnes
VIENNA - Radiologists at the University of Pisa in Italy have found high-resolution MDCT to be a reliable predictor of the degree of vascular infiltration in pancreatic cancer, light years ahead of what single-slice exams once produced, and comparable to US-guided laparoscopy.

New fusion method joins MR and CT in prostate cancer therapy planning
By Eric Barnes
VIENNA - CT and MRI, both anatomical and functional, can be combined to improve the targeting of radiation therapy of the prostate, according to researchers from the University of Nijmegen in the Netherlands. At today’s prostate imaging sessions of the European Congress of Radiology, Jorn van Dalen, Ph.D. presented a study utilizing the novel coregistration method the group created.

Lung nodule analysis makes progress, not perfection
By Eric Barnes
Researchers at the 2003 RSNA meeting examined CT lung imaging beyond the issue of nodule detection, i.e., nodule tracking, analysis, and follow-up using both automated and manual tools. These tasks are far more challenging than detection, of course, so automation's benefits to date are less convincing. Still, important progress is being made.

Cardiologist says ECGs should replace chest films for catheter placements
By Tracie L. Thompson
A recent opinion piece in Chest, the journal of the American College of Chest Physicians, argues that ECGs would be faster, easier, and more appropriate than radiographs in most cases. But the author is also quick to acknowledge the unlikelihood of a sea change in this area of American medical practice.
