Sublingual nitroglycerin improves coronary CTA
December 31, 2007 -- Nitroglycerin significantly improves the results of coronary CT angiography (CTA) by dilating the coronary arteries before scanning, researchers in Belgium have reported. Their study found that vessel lumen diameters and average volumes were larger when nitroglycerin spray was administered sublingually before scanning. Their study appears in the January issue of the American Journal of Roentgenology. Read More
Dual-source CTA improves temporal resolution for cardiac imaging
December 28, 2007 -- (Radiology Review) Dual-source CT angiography (CTA) enables noninvasive, functional cardiac analysis, including accurate assessment of left ventricular myocardial function and reliable evaluation of regional wall motion, according to a pilot study by German researchers.

VC program takes off in nonacademic setting
December 21, 2007 -- Radiologists in Belgium have built a popular virtual colonoscopy practice they credit with increasing awareness of colorectal cancer screening in their community and reducing unnecessary optical colonoscopies. The screening model offers a glimpse of what U.S.-based community screening practice might look like with a bit of reimbursement. Read More
DSCT matches angiography for stenosis detection -- even in fast hearts
December 4, 2007 -- Dual-source CT (DSCT) offers diagnostic accuracy comparable to that of invasive coronary angiography when it comes to identifying significant coronary artery stenoses, according to researchers from Germany. To test whether DSCT could match angiography in accuracy, they examined patients with suspected coronary artery disease and found DSCT angiography offered high sensitivity for detecting stenosis.

US-based minimally invasive treatments prove feasible for uterine fibroids
November 20, 2007 -- When it comes to the ultrasound-based treatment of uterine fibroids, clinicians should target patients whose benign tumors are not too big or not too small, according to two new studies. Researchers from Italy found that that percutaneous sonography-guided radiofrequency thermal ablation (RFA) was particularly adept at shrinking medium-sized fibroids, while a Japanese team found that MR-guided focused ultrasound (MRgFUS) surgery was an optimal therapy option for fibroids with specific characteristics on preoperative imaging.

Five-modality Munich trial finds high sensitivity for OC, VC
November 12, 2007 -- A virtual colonoscopy screening trial performed entirely on 64-detector-row CT found clinically significant polyps nearly as accurately as optical colonoscopy, researchers report. The Munich Colorectal Cancer Prevention Trial incorporated five separate colorectal cancer screening modalities in the same screening cohort. The researchers presented their results at the recent 2007 International Symposium on Virtual Colonoscopy in Boston. Read More
VC in elderly patients yields extracolonic advantage
November 7, 2007 -- Virtual colonoscopy is a valuable screening tool in symptomatic individuals age 70 and older, yielding diagnostic benefits far beyond the scope of barium enema exams, which remain common in the U.K. due to staffing and equipment issues, researchers report in this month's American Journal of Roentgenology.

Italian multicenter VC trial screens higher-risk cohort
October 17, 2007 -- BOSTON - One of the largest virtual colonoscopy trials ever aimed at a higher-risk screening population has yielded good results across 12 sites in Italy. Researchers presented the first results of the study on Tuesday at the International Symposium on Virtual Colonoscopy. Read More
Advanced liver imaging shapes surgical strategies
September 18, 2007 -- The days of planning liver interventions on the strength of a few CT or MR reconstructions may be numbered. Researchers from Germany and beyond are honing a set of advanced planning tools that not only provide high-resolution color-coded 3D visualization of the liver parenchyma and vasculature, but offer quantitative views of the intrahepatic vessel branching system and the risks of cutting at a given point in the organ.

ESR adopts 'bigger is better' membership strategy
August 13, 2007 -- Although the Radiological Society of North America continues to host the world's largest radiology meeting, the Vienna-based European Society of Radiology (ESR) hopes to surpass RSNA's membership numbers, partially through an innovative low-cost membership drive. The philosophy behind the membership drive can be summed up with ESR's new slogan: "The bigger we are -- the better we can serve you." Read More
