Dynamic Cardiovascular MRI: Principles and Practical Examples

It’s a brave new world in cardiac imaging, and it’s vital to keep current, especially for those who have yet to take the boards. Cardiac was recently named as an independent section of the boards. It’s sink or swim, and if you seek a fully loaded life raft, read on.

New tagging, subtraction techniques aim for better compliance in VC

By Eric Barnes

Researchers are continuing their efforts to perfect stool tagging and digital subtraction techniques, hoping to someday make virtual colonoscopy easy enough for the masses -- and potentially save many lives. Radiologist Dr. Michael Zalis, who heads up CT colonography at Massachusetts General Hospital in Boston, talks about minimal prep imaging and digital subtraction techniques.

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.

Radiologist reports initial impressions of 40-slice CT

By Tracie L. Thompson

VIENNA - The CT world has been buzzing since the introduction of the next generation of multislice CT scanners at last year's RSNA meeting. Attendees at the European Congress of Radiology got a sneak peak at the capabilities of these new machines.

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 MR approach quantifies brain metabolite concentrations

By Tracie L. Thompson

VIENNA - Chinese researchers have developed a method to quantitatively measure concentrations of brain metabolites using a position resolved spectroscopy sequence (PRESS) in MRI, according to a presentation Saturday at the European Congress of Radiology.

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.
