Shalmali Pal[email protected]Digital X-RayEx-smokers can regain BMD; primary care docs fail to track osteoporosisSmokers who quit could actually see an increase in bone mineral density (BMD). But any benefits derived from choosing a cigarette-free lifestyle may be for naught if referring physicians don't follow through on BMD test results and steer their patients toward appropriate follow-up and treatment, according to two studies in the Journal of Women's Health.January 30, 2007MRIMRI of cardiac devices OK, but requires following strict guidelinesTwo new papers in the Journal of Cardiovascular Magnetic Resonance offer advice on using MRI in patients with pacemakers and implantable cardiac defibrillators. Electrophysiologic and magnet-related issues that must be considered include magnetic field interactions, MRI-related heating, and functional changes, said the authors from the University of Southern California and other Los Angeles-based institutions.January 29, 2007CTMRI should be preferred test for suspected acute strokeMRI should replace CT as the first-line test for accurate diagnosis of suspected acute stroke, according to a study published today in the Lancet. The authors found that MRI was superior to CT for diagnosing ischemic stroke, as well as acute and chronic hemorrhage. While cost is an issue with MRI, its greater diagnostic accuracy would justify the extra expense, they said.January 25, 2007MRIGive a little bit! Give a little bit of your temporal cortex to meWhen it comes to being charitable, Bill and Melinda Gates, Oprah, and Brangelina may have more in common than just open wallets. A recent fMRI study indicates that a specific region of the brain is linked to altruism and empathy. Interestingly enough, this particular region is not associated with the neurological areas that are responsible for higher functioning.January 25, 2007MRIFrom staging to lymph node status: Studies look to refine cervical cancer diagnosis, treatmentSeveral new studies examined the roles of imaging and radiotherapy for cervical cancer staging and treatment. Canadian researchers sought a connection between interstitial fluid pressure and MR-derived kinetic-modeling parameters, while U.S. investigators in a national trial compared CT to MRI for presurgical assessment. A third study in Italy scrutinized lymph node involvement and preoperative chemoradiation.January 22, 2007InterventionalTumor regrowth generally calls for second UAE procedureIncomplete tumor infarction is the main reason that some patients undergo uterine artery embolization (UAE) a second time, according to a study that looked at the indications and technical reasons for another UAE procedure. In addition, many of these "repeat customers" will require ovarian artery embolization (OAE) as well.January 22, 2007MRIMR arthrography depicts tears, instability in triangular fibrocartilage complexThe triangular fibrocartilage complex (TFCC) is the main stabilizer of the distal radioulnar joint, and when injuries occur in the form of tears, the latter will influence imaging outcome. But these tears may go unseen on traditional MRI and/or arthroscopy. Several studies assessed the usefulness of MR arthrography in peripheral tears and in cases of carpal instability.January 18, 2007MRIMultiple MR protocols pose triple threat in prostate cancer screeningProstate cancer screening with a combination of MR techniques can accurately detect and localize prostate cancer -- and possibly avoid needless biopsy, according to researchers from Tokyo. They used three different image interpretation protocols and found that each one offered something unique in prostate cancer detection.January 17, 2007Musculoskeletal RadiologyAuntMinnie.com Orthopedic Imaging InsiderJanuary 14, 2007MRIBreast MR shows exceptional sensitivity for spotting DCISMRI has been unfairly labeled as insensitive for diagnosing ductal carcinoma in situ (DCIS). In fact, DCIS cases found on MR are reflective of an advanced biological disease profile and not necessarily overdiagnosis, according to researchers in Germany. They performed a study of more than 5,000 women, comparing MRI to mammography for DCIS diagnosis.January 11, 2007Previous PagePage 14 of 100Next PageTop StoriesMolecular ImagingAmyloid PET scans validated in racially diverse patientsChanges in care plans occurred in 59% of individuals after PET scans.Womens ImagingLimited access to PCPs thwarts mammography screening uptakeUltrasoundPOCUS rules out pulmonary congestion in kidney patientsEconomicsLow-value imaging services part of high Medicare costsDigital X-RayAI helps clinicians identify misplaced endotracheal tubes
