As a result, DHEA replacement therapy may be useful for preventing and treating osteoporosis in postmenopausal women, they suggested.January 3, 2005MRI3D contrast MRA may be optimal for evaluating aortic dissectionThree-dimensional contrast-enhanced MR angiography (3D CE-MRA) is the way to go for diagnosing and treating aortic dissection, according to a group from Changhai Hospital in Shanghai, China. The advantages of 3D CE-MRA in this setting are its speed, efficacy, and noninvasiveness.December 29, 2004MRIPreop MRI to measure CBF may benefit neonates with heart defectsAdvances in neonatal cardiac surgery have vastly improved newborn survival rates, but impaired neurodevelopment and neurological damage remain major concerns in these high-risk patients. Researchers from Philadelphia have found that using MRI to measure cerebral blood flow in severe cases of congenital heart defects may identify a preoperative risk factor for poor neurocognitive outcome.December 28, 2004BreastMammo-screened tumors require less toxic treatmentWomen with breast cancer spotted on a screening mammogram may be spared highly invasive and toxic treatment regimens, according to a study in the latest issue of the American Journal of Roentgenology.December 28, 2004Digital X-RayStudies examine osteoporosis management in women with fracturesDoctors often overlook osteoporosis and its associated risks in women who present with fractures, according to two recent studies. The first looked at bone mineral density (BMD) thresholds for pharmacologic intervention to prevent fractures. The second evaluated the management of osteoporosis in fracture patients.December 26, 2004BreastBreast US readers need more practice with postop changesPotential investigators for the American College of Radiology Imaging Network (ACRIN) 6666 breast ultrasound trial must continue to hone their skills in interpreting postoperative images, according to a presentation at the 2004 RSNA meeting in Chicago.December 21, 2004Practice ManagementStudy asks: If residents snooze more, do patients lose out more?Undoubtedly, the Accreditation Council for Graduate Medical Education had the best intentions in limiting resident working hours to 80 hours per week.

But others have just recently learned that the same concept applies to hitching up full-field digital mammography (FFDM) and PACS. As it turns out, putting PACS before FFDM can help ensure a pleasant journey into the digital era, and help familiarize users with the ride.December 13, 2004Previous PagePage 46 of 100Next PageTop StoriesDigital X-Ray3D DEXA reveals lower bone density in diabetes patients3D DEXA revealed differences that conventional bone mineral density measurements did not detect.MRIGadolinium in ... beer?UltrasoundMWA safe, effective in treating hyperthyroidism with nodulesAIAI model shows promise for diagnosing prostate cancerCT'Habitat' AI model helps stratify lung nodule disease risk on LDCT
