CARS report: New CAD tool follows lung nodules over time June 30, 2009 -- BERLIN - It's easy to complain about the insanity of tracking lung nodule changes in multiple CT scans over time, but at least one group is doing something about it, according to a presentation at the Computer Assisted Radiology and Surgery (CARS) meeting.
UFE provides long-term relief of fibroid symptoms June 30, 2009 -- Uterine fibroid embolization (UFE) provides long-term relief for a variety of fibroid symptoms, according to a study by Austrian researchers to be published in the July issue of the American Journal of Roentgenology.
CARS report: Personalized medicine will dominate future care June 26, 2009 -- BERLIN - Medicine is undergoing a historic transition, moving away from a cookie-cutter model of care and toward individualized treatment strategies based on patient-specific models of disease and treatment. Imaging, biology, and mathematics are at the center of this new paradigm, according to Dr. Michael Vannier, who spoke at the opening of the 2009 Computer Assisted Radiology and Surgery (CARS) meeting.
Adding RFA to chemo better treats colorectal liver metastases June 22, 2009 -- Patients with unresectable colorectal liver metastases who receive radiofrequency ablation (RFA) with chemotherapy treatment have longer progression-free survival than patients treated with chemotherapy alone, according to a new study by Dutch researchers.
Dose can be reduced by 75% in pediatric chest CT exams June 18, 2009 -- The radiation dose of pediatric MDCT exams can be reduced by as much as 75% without compromising the ability to detect small lung nodules in young children, according to a study published in the July issue of Academic Radiology.
Hybrid coronary CTA, SPECT offer less radiation, shorter scan time June 15, 2009 -- TORONTO - Swiss researchers have developed a hybrid cardiac imaging method that combines coronary CT angiography (CTA) with SPECT myocardial perfusion imaging to predict relevant coronary lesions with considerably less radiation dose and scanning time.
Readers undaunted by VC CAD false positives June 12, 2009 -- Radiologists examining data from virtual colonoscopy studies can easily dismiss increasing numbers of false-positive detections generated by computer-aided detection (CAD) systems, researchers from the U.K. report. But the presence of more false positives makes reading less efficient.
MR stress alone sufficient for myocardial perfusion June 12, 2009 -- Use of an automated postprocessing tool eliminates the need for both a stress and rest exam in myocardial perfusion MRI, according to researchers from Germany. They found that quantitative assessment of stress MRI images alone delivers the same diagnostic performance as semiquantitative evaluation of both stress and rest perfusion exams.
Facing Mo-99 shortage, nuclear medicine economizes June 11, 2009 -- What would a world without molybdenum-99 (Mo-99) look like? That's a question U.S. nuclear medicine physicians are contemplating as limited Mo-99 supplies decay by half every 66 hours.
