Shalmali Pal[email protected]MRIMRgFUS an option for many women seeking less invasive fibroid treatmentNearly a quarter of U.S. women suffer from clinically symptomatic uterine fibroids. While treatment options have moved beyond hysterectomy, researchers from New York City asked how many of these women are eligible for a less invasive treatment, such as MR-guided focused ultrasound (MRgFUS). A fair number, according to the group, but refining MRgFUS will open it up to a broader patient population.June 17, 2007MRIHARM makes good on poststroke MR, exposes blood-brain barrier disruptionWhen stroke patients undergo standard FLAIR MR imaging, delayed gadolinium enhancement in the cerebral spinal fluid space -- or what researchers at the National Institute of Neurological Disorders and Stroke are calling hyperintense acute reperfusion marker (HARM) -- may indicate early blood-brain barrier disruption, reperfusion injury, hemorrhagic transformation, and poor clinical outcome. HARM also could help broaden the therapeutic window for stroke patients.June 14, 2007MRIDiffusion-weighted MRI: The cornerstone of neuroimaging-based stroke studiesA multitude of new studies published in the journal Stroke examine the increasing validity of MR in stroke imaging. The technique discussed in two papers is the diffusion-perfusion mismatch model with the goal of devising a "simple and practical means" of pinpointing the ischemic penumbra and identifying patients who are more likely to respond to reperfusion therapy. In the third, DWI results are used to create an outcome prediction model.June 13, 2007Radiation Oncology/TherapyBreast radiotherapy studies propose shorter treatment, confirm lack of cardiac riskThe toxicity associated with radiation therapy for breast cancer is the focus of two new papers. In the first, Philadelphia-based researchers tightened up the radiotherapy course length, partly in an effort to reduce skin toxicity. And in the second, the authors investigated if radiation treatment increased the risk of cardiac toxicity.June 12, 2007MRIAuntMinnie.com MRI InsiderJune 10, 2007MRI3-tesla MRI sheds light on shading sign in endometriosisOn T1-weighted MRI, endometrial cysts generally show high signal intensity. Unfortunately, so does other gynecological pathology. Differentiating endometrial cysts from other hemorrhage adnexal cysts is important for adequate treatment, according to Japanese researchers. They compared the MR manifestations of endometrial cysts using both 1.5- and 3-tesla MRI.June 7, 2007Womens ImagingAuntMinnie.com Women's Imaging InsiderJune 3, 2007InterventionalFibroid arterial perfusion on aortography forecasts incomplete UAE treatmentInterventionalists in the U.S. and France have identified several characteristics that can target patients who may require ovarian artery embolization (OAE) to ensure complete and successful fibroid treatment. They based their criteria on postuterine artery embolization (UAE) aortography results.May 31, 2007Image-Guided SurgeryMR signal, nonperfusion drive long-term success of MR-guided focused US therapyBERLIN - At least 20% of a uterine fibroid treated with MRI-guided focused ultrasound (MRgFUS) therapy must be properly ablated to achieve long-lasting volume changes, according to Boston researchers who are experienced with the technique. The team presented its work this week at the International Society for Magnetic Resonance in Medicine (ISMRM) meeting.May 22, 2007MRICoronary MR protocol picks veins favorable for resynchronization therapyBERLIN - One-third of cardiac resynchronization therapy procedures in patients with congestive heart failure (CHF) experience hemodynamic failure, while another 12% are marred by implantation failure. MR coronary vein imaging holds promise for preprocedural assessment of the veins in CHF patients, according to a presentation Monday at the International Society for Magnetic Resonance in Medicine (ISMRM) meeting.May 21, 2007Previous PagePage 9 of 100Next PageTop StoriesCTNew benchmark helps monitor cumulative CT radiation doseThe findings highlight the need for systematic dose tracking and rigorous justification of imaging.Radiation Oncology/TherapyStudy questions routine use of radiotherapy after bone surgeryUltrasoundCEUS outshines color Doppler imaging for indeterminate kidney lesionsWomens ImagingWomen's Imaging MinnieCast, Episode 2: Risk-based vs. annual mammography screening, part 1Digital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputations
