Shalmali Pal[email protected]MRIIn living color: Stanford researchers peer into human visual system with fMRIOn a daily basis, the majority of people in the world take their ability to perceive color for granted. But how exactly does the human visual system interpret color and what drives that interpretation? Researchers at a lab dedicated to vision and imaging technology at Stanford University are hoping to answer that question with the help of functional MRI.September 4, 2000BreastTask, lesion type make a difference in digital mammography displayAs a first step in determining how digital mammography will be applied in daily practice, researchers polled the display preferences of radiologists in a study published in the September issue of Radiology. Preferences vary widely depending on the machine and diagnostic task at hand, the researchers found.August 30, 2000Molecular ImagingPET imaging shows brain areas activated in Tourette syndromeWhile tics are the defining symptom of Tourette Syndrome (TS), the neurological mechanics behind them are poorly understood. Some of those mysteries are now being unlocked by PET, which showed extensive activation of behavior-associated brain areas in TS patients, according to a study published in the August Archives of General Psychiatry.August 29, 2000CTDynamic CT perfusion data may help widen window for stroke treatmentHoping to expand the period during which a stroke patient can undergo treatment successfully, German researchers used CT perfusion imaging (CTP) for assessment of acute stroke of the middle cerebral artery.August 27, 2000MRIMR helps distinguish rheumatoid arthritis from other painful joint conditionsAs the trend to diagnose and control rheumatoid arthritis in the early stages gains ground with rheumatologists, gadolinium-enhanced MRI of RA can play a vital role in an aggressive treatment process, according to a study in the August 2000 issue of Radiology.August 22, 2000InterventionalAngioplasty of ostial renal artery stenoses lasts longer with stentingThe treatment of ostial stenoses can benefit from stent-assisted percutaneous transluminal renal angioplasty (PTRA), but stand-alone balloon PTRA works just fine for non-ostial renal arterial stenosis, according to Swiss researchers.August 17, 2000Radiology EducationSocieties offer scholarships -- and more -- to improve education for radiologistsAugust 16, 2000MRIClinician journals replete with imaging issuesCurrent Opinion for cardiology, pediatrics, and oncology are among the journals with editions available for free at a Web site maintained by publisher Lippincott Williams & Wilkins of Philadelphia.August 14, 2000MRIThe pitfalls of MR imaging of the elbow -- and strategies for avoiding themHistorically, the prospect of reading elbow MR images may have had radiologists burying their heads in their hands. "It used to be that before the advent of PACS, MRI of the elbow was relatively straightforward," joked Dr. Garry Gold at the June "MR Advances in Musculoskeletal Imaging and Neuroradiology" conference sponsored by Stanford University of Stanford, CA. "You found one in the 'in' slot in the reading room, and then you found a place to hide it."August 13, 2000InterventionalNew interventions show promise in battling head and neck cancersTwo new weapons have emerged in the fight against head and neck cancer. Israeli investigators have released early data indicating that the experimental drug Multikine can reduce tumors significantly. In other news, the gene-deleted adenovirus Onyx-015, when paired with chemotherapy, also has the potential to shrink head and neck tumors, and prevent them from recurring.August 10, 2000Previous PagePage 90 of 100Next PageTop StoriesWomens ImagingFalse-positive DBT findings differ between AI, radiologistsFalse-positive DBT findings differed between AI and radiologists in population-based breast cancer screening.Practice ManagementWhat is the real impact of the 2025 MPFS Proposed Rule on radiology practices?Practice ManagementHPI: Radiology attrition varies by gender, specialty, and practice typeRadiation Oncology/TherapyASTRO: Short prostate SBRT reduces side effects, but not PSA levelsSponsor ContentDigital Innovations Shaping the Future of Radiology
