Shalmali Pal[email protected]Advanced Visualization3D diagnosis and planning bring orthodontists closer to 'anatomic truth'The goal of orthodontic imaging is to represent reality as closely as possible, and increasingly, technology is making the job easier. As 2D imaging gives way to more sophisticated 3D methods, orthodontists can rest assured that they are capturing patients and their treatment needs more accurately.June 1, 2005UltrasoundCanadian cardiologists define low risk for women with chest painChest discomfort is often the first manifestation of coronary artery disease in both men and women. Unlike men, however, women don't always benefit from traditional cardiac testing methods such as coronary angiography. But rather than subject women to a battery of other exams, what is needed is a better understanding of the clinical manifestations of heart disease in women, according to Canadian researchers.May 29, 2005MRIRacial profiling: fMRI links brain activity and black-white biasA variety of factors help determine how we each feel about, and react to, people of different ethnicities. These factors are closely tied to a neurological reaction that may determine our emotional response to race -- whether we are conscious of it or not. A number of recent neuroimaging studies have investigated the connection between our brains and race processing.May 26, 2005Digital X-RayOrthodontist advises practice needs assessment before investing in DRSAN FRANCISCO - The radical revolution that had digital radiography (DR) replacing film-based imaging may not have come to pass, but in the orthodontics field, DR does have its advantages over traditional imaging, according to a presenter at the American Association of Orthodontists (AAO) meeting.May 24, 2005MRIAuntMinnie.com MRI Radiology InsiderMay 22, 2005BreastPPV alone not enough to assess mammo screening programWhen it comes to rating the overall quality of mammography screening programs, sensitivity should take precedence over specificity, according to a commentary in the May American Journal of Roentgenology.May 22, 2005MRINeuroimaging study bolsters genetic basis for feeling downEven on a genetic level, people who suffer from depression may be shouldering a heavy burden. First, they are carriers of a brain anomaly that makes them prone to the disorder. Second, parts of their brain may be stuck in a neurochemical loop, thwarting the ability to regulate negative emotions. Neuroscientists used multiple imaging modalities to study this genetic connection between anatomy, function, and emotion.May 18, 2005MRILow-grade hernia may slip back even after diskectomyRecurrent lumbar disk herniation occurs in 5% to 11% of patients treated with surgery. One potential risk factor for a failed diskectomy is the size of the annular defect; another is disk herniation volume. Now Swiss investigators have recommended adding the degree of degeneration to the list of risk factors.May 9, 2005Digital X-RayContrast entry into blood vessel during HSG no cause for alarmHysterosalpingography remains the imaging technique of choice for visualizing the upper reproductive tract in infertile women, and the addition of contrast agents has enhanced this exam. While complications have been reported because of this pairing, there are still questions as to how serious these risks are. Not serious enough to terminate a hysterosalpingography (HSG) procedure, according to Italian radiologists.May 8, 2005BreastBreast imaging trends show longer waits for screening mammo, more biopsiesMammography services across the U.S. are being challenged by staffing shortages that can only worsen as more women reach screening age. Meanwhile, at one East Coast institution, biopsy rates are on the rise.May 5, 2005Previous PagePage 40 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
