Analysis finds variance in uptake of amyloid PET tracers
May 28, 2015 -- PET scans can detect varying levels of amyloid in the brain that change with age and the presence of a genotype linked to Alzheimer's disease, according to a Dutch study in the May Journal of the American Medical Association. The findings may enable clinicians to better tailor which patients receive the scans.
Specialist imaging search tool shows promise
May 27, 2015 -- Radiologists increasingly face information overload in their interpretation tasks, but a medical image retrieval system combining text-based searches and content-based image retrieval techniques is assisting more of them.
Revealed: Big variations in recall rates for screening
May 27, 2015 -- Startling new evidence has shown that women screened for breast cancer in the U.S. were recalled for workup four to six times more frequently than women screened in Denmark, according to a study published by the International Journal of Cancer.
New breast tomo CAD shows high sensitivity
May 26, 2015 -- A new computer-aided detection (CAD) algorithm for digital breast tomosynthesis studies delivers high sensitivity and an acceptably low false-positive rate, according to Italian researchers. In a retrospective study of nearly 200 women who underwent DBT for breast cancer screening, CAD demonstrated sensitivity of 89% with a false-positive rate of 2.7 per breast.
CTC CAD boosts readers' attention -- but to what effect?
May 25, 2015 -- The use of computer-aided detection (CAD) significantly alters the search and identification of polyps among readers of CT colonography (CTC) data, according to a new study in the June issue of European Radiology. In particular, CAD drew radiologists' attention to polyps more quickly, but it also prompted them to spend more time interpreting scans.
Transfer learning speeds image segmentation
May 22, 2015 -- The development of automated image segmentation schemes can be enhanced significantly with the application of a process called transfer learning, according to a new Dutch study published in the May edition of IEEE Transactions on Medical Imaging.
Strike vote looms at Austria's leading hospital
May 21, 2015 -- VIENNA - Radiologists and other doctors at Austria's largest hospital are voting this week on whether to launch a strike, following months of failed negotiations over pay and working conditions. Find out what Dr. Thomas Szekeres, president of the Vienna medical chamber, has to stay about the strike threat.
Patient cooperation key to respiratory-gated PET/CT
May 21, 2015 -- The combination of standard PET/CT with respiratory-gated PET/CT can significantly improve the diagnosis of small colorectal liver metastases, but patient cooperation is a must for a successful scan, according to a Norwegian study published online on 14 May in the European Journal of Radiology.
Israeli start-up eyes big-data tools for imaging analysis
May 21, 2015 -- For Israeli image analysis software developer Zebra Medical Vision, size definitely matters. The start-up believes its database of 10 million curated imaging studies and extensive collaborations with researchers around the world will take image analysis algorithms to a whole new level.
Dr. Adrian Dixon, breast experts & joggers excel at DRK
May 20, 2015 -- HAMBURG - "Sherlock Homes is nothing compared to a radiologist," Dr. Adrian Dixon pointed out in an interview with the congress newspaper at last week's German Radiology Congress (DRK) in Hamburg. Dixon received honorary membership of the German Radiological Society at the meeting.
