Vigilance is crucial for radiology quality control
August 3, 2012 -- A quality control management system can yield important benefits for radiology departments. But long-term success requires ongoing monitoring of its use and training, according to research from the University of Maryland Health System.
AAPM: Spectral mammography could measure breast density
August 2, 2012 -- Spectral mammography used during breast screening can measure tissue density with high accuracy -- potentially improving the assessment of breast cancer risk, according to research presented at the American Association of Physicists in Medicine (AAPM) annual meeting in Charlotte, NC.
Reactions to gadolinium MRI contrast are rare, but can recur
August 2, 2012 -- Korean researchers have found that patients who previously experienced immediate adverse reactions to gadolinium-based MRI contrast agents have a 30% recurrence rate when given the media a second time, according to a study in the August issue of Radiology.
Japanese team finds more flat polyps with virtual colonoscopy
August 1, 2012 -- Flat colorectal lesions aren't easy to detect at virtual colonoscopy. But a group from Japan did quite well finding them after patients underwent bowel cleansing and automated insufflation before CT scanning, according to a new study in Acta Radiologica.
Imaging shows how yoga injuries affect tendons, cartilage
August 1, 2012 -- Yoga, that poetic and wildly popular integration of human body, breath, and mind that has swept the U.S. in recent years, does cause musculoskeletal problems, though rarely, according to a new study published in the August American Journal of Roentgenology that used imaging to assess yoga injuries.
Study shows PEM's potential in extremity imaging
July 31, 2012 -- Positron emission mammography (PEM) is branching out from breast imaging, as researchers at Johns Hopkins University have used the modality with preliminary success to view osteoarthritis in patients' hand joints.
Imaging use rises for terminally ill Medicare cancer patients
July 30, 2012 -- A new study published online July 30 in the Journal of the National Cancer Institute indicates that the use of advanced imaging is growing faster among patients with stage IV cancer than it is among patients with earlier stages of disease. The findings could mean that imaging is being overused in terminally ill patients.
Moments in Radiology History: Part 7 -- Early x-ray treatments
July 30, 2012 -- Today, diagnostic radiology and radiation oncology are distinctly separate disciplines -- but things weren't always that way. In fact, the early pioneers of radiology began experimenting with the new rays for therapeutic purposes almost as soon as they were discovered.
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%.
