3D CT detection of perfusion defects mirrors SPECT March 8, 2009 -- VIENNA - Three-dimensional images from normal coronary CT angiography scans are highly sensitive for detecting fixed perfusion defects compared to myocardial SPECT. A special reconstruction technique performed with customized software does the job without the need for additional radiation or contrast.
ECR delivers new findings on digital breast tomosynthesis March 7, 2009 -- VIENNA - Delegates at the 2009 European Congress of Radiology (ECR) saw a series of presentations Friday unveiling new findings and key updates on digital breast tomosynthesis (DBT). As the body of research builds in this relatively unexplored field, the advantages and limitations of DBT compared with conventional full-field digital mammography and other modalities are becoming better defined.
Triple reading boosts breast cancer detection rate March 7, 2009 -- VIENNA - Sending suspicious mammograms to a third expert reader can boost the cancer detection rate of a breast screening program by a statistically significant amount, according to a presentation by German researchers at this week's European Congress of Radiology.
MRI finds hip injuries in karate fighters March 7, 2009 -- VIENNA - MRI evaluation of a group of karate fighters has found a high rate of femoroacetabular impingement, according to research from the University of Bern presented Saturday at the 2009 European Congress of Radiology.
Minimal prep VC nearly as sensitive, better tolerated March 7, 2009 -- VIENNA - A new study from the U.S. and Japan found that full-laxative and minimum-laxative virtual colonoscopy had equivalent sensitivities for detecting colorectal polyps 6 mm and larger, though specificity fell in the minimum-prep regimen. The patients were happy to skip the laxatives, however.
320-slice coronary CTA permits much lower contrast dose March 6, 2009 -- VIENNA - Single-beat scanning not only enables significant radiation dose reductions in coronary CT angiography (CTA), the short duration of the scan permits drastically lower contrast doses as well, at least in patients with regular heartbeats and no arrhythmias.
Integrating lung CAD with PACS boosts utilization March 6, 2009 -- VIENNA - Integrating computer-aided detection (CAD) technology into PACS workstations can dramatically boost its usage for detecting pulmonary nodules on MDCT studies, according to research from the University of Munich in Germany.
Adding CAD to virtual colonoscopy saves lives and money February 24, 2009 -- Adding computer-aided detection (CAD) increases the efficiency and cost-effectiveness of VC screening, according to a new model-based analysis. Most of the gains resulted from the use of CAD with inexperienced readers, but even with experienced readers VC cost-effectiveness improved substantially.
Finnish study finds unnecessary pediatric CT exams February 20, 2009 -- Nearly one-third of a sample of pediatric CT scans from a hospital in Finland were found to be clinically unjustifiable, according to research published online in the journal European Radiology.
MRI, MDCT err in estimating cardiac functional parameters February 20, 2009 -- MRI and MDCT assessments of left ventricular functional parameters were inaccurate when evaluated on a moving heart phantom with known parameters, according to a study in European Radiology. CT, particularly dual-source CT, did outperform MRI, however.
