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.
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.
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.
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."
Giant virtual reality chamber boosts 3D echo accuracy August 2, 2007 -- Have you ever diagnosed a three-foot-tall 3D heart? Talk about cardiomegaly. Researchers from the Netherlands who survived the experience found they could diagnose valve defects that went unnoticed in a standard 2D exam. At the 2007 Computer Assisted Radiology and Surgery (CARS) meeting in Berlin, Anton Koning, Ph.D., from Erasmus University Medical Center in Rotterdam discussed how 3D visualizes complex pathology of the heart and how image display can be improved with different kinds of VR (virtual reality) systems.
