Cardiac MRI shows how triathletes' hearts adapt September 1, 2010 -- With the help of 1.5-tesla cardiac MRI, German researchers have found that the human heart adapts to triathlon training by developing greater muscle mass and wall thickness, as well as larger left atria and larger right and left ventricles, according to a study to be published in the October issue of Radiology.
Contrast MRI visualizes bowel damage caused by celiac disease September 1, 2010 -- Contrast-enhanced MRI dynamic evaluation of the bowel wall can effectively visualize inflammation caused by celiac disease, aiding the assessment of patients with this condition, according to a study in the September issue of Radiology.
MRI-compatible incubator increases procedure use for neonates August 31, 2010 -- MRI exams can provide valuable information about neurological abnormalities in preterm infants. But the process of having an MRI exam can be hazardous to very fragile and unstable neonates, limiting the value of this powerful technology -- unless you have an MRI-compatible incubator.
U.K. audit reports survival stats of cervical cancer patients August 27, 2010 -- A large-scale audit of women treated throughout the U.K. for cervical cancer in 2001 and 2002 has reconfirmed that the combination of radiation therapy and chemotherapy is more effective than radiation therapy alone, according to findings published in the September issue of Clinical Oncology.
Breast CAD helps find lobular carcinoma in situ lesions August 20, 2010 -- Computer-aided detection (CAD) is making an elusive breast abnormality, lobular carcinoma in situ, a little clearer by highlighting the calcifications that often surround it, according to a new study from Wende Breast Care in Rochester, NY.
FDG-PET before RT can modify planned NSCLC treatment August 11, 2010 -- FDG-PET scans of non-small cell lung cancer (NSCLC) patients reviewed before radiation therapy (RT) may lead to significant changes in treatment strategy and radiation therapy planning, according to a study in the August issue of the American Journal of Roentgenology.
Combined PET/CT CAD improves lung nodule detection August 6, 2010 -- Researchers in Japan have developed computer-aided detection (CAD) software that detects lung nodules in PET/CT images of lung cancer screening patients. Applying a combined CAD system to both modalities instead of CT or PET alone nearly doubled the number of solitary pulmonary nodules detected.
Enhanced reference standard boosts CTA accuracy August 4, 2010 -- Borrowing a technique from the virtual colonoscopy playbook, researchers from South Carolina and Germany found that coronary CT angiography (CTA) is better than previously thought compared to catheter-based coronary angiography -- in fact the two tests are essentially equivalent, they said.
Constipated kids don't need abdominal x-rays August 4, 2010 -- The practice of ordering an abdominal x-ray exam for constipated children to assess the presence of retained feces or to confirm a diagnosis made during a physical exam should be stopped, as the procedure is of limited value, according to an analysis published online in Pediatric Radiology.
