June 2008 Briefing - Radiology
Here are what the editors at HealthDay consider to be the most important developments in Radiology for June 2008. This roundup includes the latest research news from journal articles, as well as the FDA approvals and regulatory changes that are the most likely to affect clinical practice.
Imaging Identifies Risk of Recurrent Breast Cancer
WEDNESDAY, June 25 (HealthDay News) -- A high-resolution imaging method can accurately predict the risk of tumor recurrence in women with invasive breast cancer, researchers report in the July issue of Radiology.
Prediction Rule Identifies Risk of Osteoporotic Fracture
WEDNESDAY, June 25 (HealthDay News) -- A prediction rule based on a heel stiffness index and four clinical factors can identify which elderly women are at high risk of osteoporotic fracture, according to a report in the July issue of Radiology.
Coronary Calcium Score Shows Usefulness in Two Studies
TUESDAY, June 24 (HealthDay News) -- Coronary artery calcium (CAC) score was a better predictor for coronary heart disease and total cardiovascular disease than carotid intima-media thickness in middle-aged and older adults, and CAC scoring is effective for stratifying risk even in the elderly, according to studies in the June 23 Archives of Internal Medicine and the July 1 Journal of the American College of Cardiology.
Automated Imaging Method Identifies Alzheimer's Patients
TUESDAY, June 24 (HealthDay News) -- An automated method to measure hippocampal volume can accurately distinguish between patients with Alzheimer's disease, mild cognitive impairment or healthy elderly patients, according to research published in the July issue of Radiology.
Low-Dose Ionizing Radiation Seen As Healthful
MONDAY, June 23 (HealthDay News) -- Chronic whole-body exposure to low-dose ionizing radiation -- principally gamma radiation -- could reduce the incidence of cancer and cancer mortality, according to an article published in the summer issue of the Journal of American Physicians and Surgeons.
Long-Pulsed Dye Laser Superior for Sun Damage
MONDAY, June 23 (HealthDay News) -- In patients with sun-damaged skin, treatment with long-pulsed dye laser rejuvenation produces better outcomes than treatment with intense pulsed light, according to a report published online June 18 in Lasers in Surgery and Medicine.
Article Examines Use of 'Key Opinion Leaders' in Drug Sales
FRIDAY, June 20 (HealthDay News) -- Influential doctors known as "key opinion leaders" are paid generous fees to influence their peers to prescribe a company's drugs and may in fact be considered salespeople by the industry, according to an article in the June 21 issue of BMJ.
Radiofrequency Ablation Benefits Lung Cancer Patients
THURSDAY, June 19 (HealthDay News) -- Radiofrequency ablation, an accepted treatment for non-surgical liver cancers, can yield sustained complete responses in patients with primary and metastatic lung tumors, according to an article published online June 18 in The Lancet Oncology.
Salvage Radiation Improves Prostate Cancer Survival Time
TUESDAY, June 17 (HealthDay News) -- In men with a recurrence of prostate cancer and a prostate-specific antigen doubling time of less than six months, salvage radiation can increase disease-specific survival, according to a report published in the June 18 issue of the Journal of the American Medical Association.
CT Lung Cancer Screenings Show Mixed Results
FRIDAY, June 13 (HealthDay News) -- In patients at high risk for lung cancer, regular helical computed tomographic screening may reduce long-term lung cancer-specific mortality. Because of other mortality risks associated with smoking, however, it may have a less significant effect on reducing overall mortality, according to research published in the July issue of Radiology.
Cancer Costs Increasing Due to More Treatment
WEDNESDAY, June 11 (HealthDay News) -- The costs associated with treating cancer in the elderly have largely increased due to more patients receiving surgery and adjuvant treatment, and rising prices for these therapies, researchers report in the June 18 issue of the Journal of the National Cancer Institute.
Device Allows Imaging of Eye in Glaucoma Patients
MONDAY, June 9 (HealthDay News) -- An optical coherence tomography device allows non-invasive imaging of the drainage angle and its structures in healthy individuals and patients with glaucoma, researchers report in the June issue of the Archives of Ophthalmology.
New PET Probe Images Immune System
MONDAY, June 9 (HealthDay News) -- A new probe for positron emission tomography (PET) imaging targeting the immune system allows imaging of lymphoid organs and can be used to monitor treatments involving the immune system, according to research published online June 8 in Nature Medicine.
