Eric Barnes[email protected]CTJapanese study finds VC useful for wide range of indicationsNew research on virtual colonoscopy from Japan found the technique to be helpful in diagnosing even patients without colorectal cancer and polyps, and it was especially useful for those with contraindications to conventional colonoscopy, according to a study in the Japanese Journal of Radiology.September 7, 2011CTPEG prep surprises with slightly better VC resultsPolyethylene glycol (PEG), the standard bowel cleansing preparation for conventional colonoscopy, did just a little better than magnesium citrate at virtual colonoscopy, according to researchers writing in Radiology.September 5, 2011CTRectal surgery platform more efficient for large polypsA new rectal surgery technique may do a better job than colonoscopy for removing large rectal polyps. A hybrid between transanal endoscopic microsurgery and single-port laparoscopy, the system can remove polyps of any size, even obstructing lesions, with less pain and scarring.September 1, 2011CTJACR: Experts point the way to low-dose chest CTA new article in the September issue of the Journal of the American College of Radiology offers pointers for optimizing radiation dose in chest CT scans, the third most commonly performed CT exam in the U.S.August 31, 2011CTJoint Commission issues alert on medical radiationThe U.S. Joint Commission has issued an alert on the dangers of medical radiation, sending an unmistakable signal that radiology has entered its sights in a formal way. The announcement is a sign that imaging facilities will need to pay more attention to formalizing their procedures for protecting patients from unnecessary radiation dose.August 23, 2011CT64-slice CT speeds diagnosis in multiple-casualty settingIt may seem intuitive enough that 64-detector-row CT is faster for multiple-casualty trauma than four-detector-row machines, but minutes make a big difference when patients are seriously injured, according to researchers of a new study in the September issue of the American Journal of Roentgenology.August 23, 2011CTResearchers cut CT dose for nodule follow-upFor surveillance of previously detected lung nodules, CT radiation dose can be cut to approximately 3% of the original exam dose, concludes a new study in the September edition of the American Journal of Roentgenology.August 22, 2011CTCoronary calcium scores are best for guiding statin therapyCoronary artery calcium scores generated by CT scans were far more predictive of future cardiac events than elevated high-sensitivity C-reactive protein levels, according to a new study in the Lancet that further clarifies which patients will benefit most from statin therapy.August 18, 2011MedicolegalNEJM: Radiology suits are uncommon, payouts below averageRadiologists are dragged into court less often than some other specialists -- and less often than they may think. According to a 14-year New England Journal of Medicine study, radiologists' chances of being hit with a malpractice suit and the resulting payouts were both slightly lower than for other physicians.August 17, 2011CTCTA becomes a one-stop shop with FFR measurementUsing CT to measure cardiac fractional flow reserve (FFR) is a potential game changer that could turn everyday coronary CT angiography (CTA) scans into a one-stop cardiac assessment tool, taking over some imaging tasks from other modalities.August 14, 2011Previous PagePage 99 of 258Next PageTop StoriesMolecular ImagingPET links brain receptor to emotional numbing in PTSDTo date, only a single study has investigated CB1R availability in humans exposed to trauma.Womens ImagingCEM, DBT show promise for preoperative breast cancer stagingMRIMRI illumines how the brain maintains 'representation' of phantom limbsDigital X-Ray3D DEXA reveals lower bone density in diabetes patientsMRIGadolinium in ... beer?
