Australian center halves CCTA dose using simple techniques
July 30, 2012 -- An academic heart center in Australia has cut its coronary CT angiography (CCTA) dose in half over three years using simple techniques that emphasize prospective triggering, low kV settings, and aggressive beta-blockage, according to research presented at the Society of Cardiovascular Computed Tomography meeting in Baltimore.
PET/MR equals PET/CT for lung cancer, with far less radiation
July 27, 2012 -- A pilot study conducted by German researchers and published in the August issue of Radiology suggests that PET/MRI provides diagnostic-quality images for assessing pulmonary masses in lung cancer cases, while cutting radiation dose by 75%.
Automated image processing bolsters radiology workflow
July 27, 2012 -- Although it's been around for more than a decade, multimodality image registration hasn't entered routine clinical use. But a team from the U.S. National Institutes of Health believes an automated data processing system can clear workflow hurdles, sparking adoption of imaging registration and other advanced image analysis tools.
Radiation exposure extraction tools enable dose monitoring, QA
July 26, 2012 -- The digitization of radiology has made the concept of efficient, cost-effective data mining possible, while the development of informatics tools is making such activity realistic. Two articles in the August issue of Radiology describe tools to extract radiation dose data.
UPMC slashes PACS downtime via workflow continuity model
July 26, 2012 -- PACS downtime can be dramatically reduced by adopting a workflow continuity approach that ensures access to critical functions such as reading and dictating exams in cases of system unavailability, according to researchers from the University of Pittsburgh Medical Center (UPMC).
ROMICAT II: CCTA more efficient to triage chest pain patients
July 25, 2012 -- It's more efficient to use coronary CT angiography (CCTA) to rule out coronary artery disease for chest pain patients, according to results of the long-awaited Rule Out Myocardial Ischemia/Infarction Using Computer Assisted Tomography (ROMICAT) II trial, published on Wednesday in the New England Journal of Medicine.
Health Affairs: Imaging growth slowed sharply starting in 2006
July 25, 2012 -- The growth of advanced diagnostic imaging in Medicare patients slowed to single-digit rates starting in 2006, a trend that has extended to private payors, according to a study from the August issue of Health Affairs, published online July 25. The study confirms other recent research documenting imaging's slowdown.
Cardiac cath technologist charged in hepatitis C infections
July 24, 2012 -- Federal authorities in New Hampshire have charged a traveling cardiac cath technologist with infecting patients with hepatitis C after he allegedly stole syringes containing fentanyl and replaced the dirty needles with saline solution. The case has authorities fearing an outbreak of hepatitis C in more than half a dozen states.
SCCT: Dual-energy CTA may offer more accurate look at plaque
July 24, 2012 -- A new dual-energy CT angiography (DECTA) protocol may provide a more accurate look at coronary artery calcium by eliminating artifacts that can bedevil more conventional CTA approaches, according to researchers from Virginia at this week's Society of Cardiovascular Computed Tomography (SCCT) meeting in Baltimore.
ABUS equals MRI as screening option for dense tissue
July 24, 2012 -- Automated breast ultrasound (ABUS) shows promise as a cost-effective adjunct screening modality compared to MRI for women who have dense breast tissue at mammography, according to a study published this month in the Journal of Diagnostic Medical Sonography.
