NOPR: PET changes care of more than a third of cancer patients
ARLINGTON, VA - PET imaging results have changed treatment decisions in more than a third of cancer patients scanned, according to data from a massive new PET registry that is expected to pave the way to expanded Medicare coverage of the modality. The latest results from the National Oncologic PET Registry (NOPR), unveiled last week at the American College of Radiology Imaging Network (ACRIN) fall meeting, show PET's powerful influence in managing a wide variety of cancers.
 
Norwegian study finds mixed success with electronic reports
Streamlining the process of delivering radiology reports -- and making them universally accessible -- doesn't guarantee that they'll be read any faster by clinicians. In fact, quite the opposite may occur if human behavior doesn't adapt to the changes imposed by adopting healthcare informatics.
Melanogenesis inhibition sensitizes melanoma cells to radiotherapy
NEW YORK (Reuters Health), Oct 6 - Inhibition of melanogenesis sensitizes melanoma cells in culture to gamma radiation, according to a report in the September 15 International Journal of Cancer.
Flexibility of 320-slice CT boosts cardiac imaging options
 The ability to scan a wider variety of patients -- and to do it quickly, with less contrast and far fewer artifacts -- is an important advantage of 320-detector-row CT, according to a cardiologist who has been working with the scanner since it was installed earlier this year.
CEUS shines in complex cystic renal masses
Contrast-enhanced ultrasound (CEUS) bested unenhanced ultrasound and CT for detecting cancer in complex cystic renal masses, according to research from Cattinara Hospital in Trieste, Italy.
CT-guided bronchoscopy doesn't improve lung cancer diagnosis
NEW YORK (Reuters Health), Oct 3 - The use of CT to steer bronchoscopy doesn't increase the sensitivity of lung cancer detection compared with conventional bronchoscopy, according to researchers at New York University in New York City.
Exposure to low doses of ionizing radiation linked to increased risk of cataracts
NEW YORK (Reuters Health), Oct 3 - Exposure to relatively low doses of ionizing radiation appears to increase the long-term risk of cataract formation, according to findings published in the September 15 issue of the American Journal of Epidemiology.
Lubiprostone aids precolonoscopy bowel cleansing
NEW YORK (Reuters Health), Oct 3 - Single-dose lubiprostone is well tolerated as part of colonoscopy preparation and improves colonic mucosa visualization during the procedure, Texas-based researchers report in the September issue of the American Journal of Gastroenterology.
NEJM study finds single reading with mammo CAD matches double reading
Computer-aided detection (CAD) for mammography screening has taken its share of criticism recently. A new study published this week in the New England Journal of Medicine, however, has found that use of CAD with a single reader can achieve performance comparable to double reading with two radiologists.
Flat-panel FFDM produces better image quality than CR mammography, study says
A flat-panel full-field digital mammography (FFDM) system produced better image quality than computed radiography-based mammography using digital storage phosphor, according to a study from researchers in Vienna, Austria.
Younger DCIS survivors at no higher risk of recurrence, study says
Published research suggests that women under the age of 40 who are ductal carcinoma in situ (DCIS) survivors have an increased risk of recurrent breast cancer, but a new study presented at the American Society for Therapeutic Radiology and Oncology (ASTRO) meeting begs to differ.
