Shalmali Pal[email protected]InterventionalVertebroplasty packs radiation punch, but cement injector can soften blowThe radiation dose to interventional radiologists during vertebroplasty is fairly high, according to Japanese researchers. In fact, using a 1-mL syringe technique, an operator could reach the recommended dose limits within five years. However, using a bone cement injector can reduce that risk.December 4, 2005InterventionalMammary Rosai-Dorfman mimics malignancy on imaging, biopsy reveals truthRosai-Dorfman disease is an idiopathic proliferative disorder of the histiocytes in the lymph nodes.

Successful detection depends on lesion size as well as a reader's skills.November 27, 2005Womens ImagingAuntMinnie.com Women's Imaging Radiology InsiderNovember 27, 2005MRIBreast MRS proves sensitive to all cancers but not in normal breast tissueCHICAGO - Score two points for breast MR spectroscopy (MRS): The modality was sensitive enough to catch all types of invasive cancer and was not prone to false-positive findings in normal breast parenchyma, according to presentations Sunday at the 2005 RSNA meeting.November 26, 2005CTPulmonary CTA packs a radiation punch to female breastsA large percentage of patients undergoing pulmonary CT angiography (CTA) are women of reproductive age, and radiologists need to pay more attention to the average glandular breast dose, according to researchers from Virginia. They conducted a retrospective study looking at effective radiation dose to the female breast during routine pulmonary CTA.November 23, 2005InterventionalExisting research lacking dollars-and-cents assessment of uterine fibroidsSome studies put the lifetime incidence of uterine fibroids in the U.S. at more than 80% for some women. What is the economic impact of this condition? The answer is unclear due to the lack of published research, according to a multi-institutional group that recently performed a meta-analysis of existing literature on uterine fibroids.November 22, 2005Previous PagePage 32 of 100Next PageTop StoriesInterventionalGAE reduces pain biomarkers in knee osteoarthritisGenicular artery embolization (GAE) significantly reduces key biomarkers that drive pain in patients with knee osteoarthritis.Residents/FellowsRace, ethnicity influence educational debt among radiology-bound MDsMRIMRI, CT findings correlate for assessing epicardial fat volumePractice ManagementImaging experts hope NSA enforcement bill delivers on accountabilityCTPET/CT identifies bone demineralization in breast cancer patients
