Shalmali Pal[email protected]Radiation Oncology/TherapyIs fixed dosimetry in brachytherapy a prescription for trouble?SAN FRANCISCO - The term "fixed dosimetry" may be a misnomer in that patients actually receive a wide range of radiation dose during intravascular brachytherapy, according to a presentation at the American Society for Therapeutic Radiology and Oncology meeting.November 7, 2001Industry NewsCoping with the trauma of terrorAs the emotional toll of the September 11 attacks begins to settle and move into focus, it seems appropriate to weigh the effects of trauma on medical professionals. Doctors in particular tend to push their personal feelings aside as they work long work hours under trying circumstances. However, disregarding one's own feelings can lead to long-term emotional consequences.October 31, 2001BreastACR disputes Danish mammo studyThe American College of Radiology has denounced the Nordic Cochrane Center mammography study, calling it an "incompetent statistical analysis." The Danish report, released by the Cochrane Center earlier this week and summarized in The Lancet, questions the efficacy of mammography screening for reducing death from breast cancer.October 24, 2001BreastDanish mammographers exclude dissenting opinionThe world's most controversial breast cancer researchers have apparently outdone themselves. This year's report not only repeats the message that screening mammography doesn't increase survival, but creates more controversy by omitting a dissenting conclusion from the group that reviewed the research.October 22, 2001BreastIs full-field digital mammography worth its weight in gold?Mammographers at the M.D. Anderson Cancer Center have logged nearly two years worth of time with full-field digital mammography. Their experience has been positive thus far; it has also been an expensive one.October 21, 2001BreastUltrasound marks metastatic lymph nodes for breast cancer stagingMONTEREY, CA - Ultrasound can be a useful tool for evaluating the nodal basins in breast cancer patients, while reducing unnecessary axillary node dissections. Dr. Bruno Fornage described the benefits of sonographic lymph node exploration yesterday at the 2001 Breast Imaging Conference.October 16, 2001BreastBIC presenter offers ways to reduce false-positive breast biopsiesMONTEREY, CA - Women who undergo core-needle biopsy for breast cancer detection can be just as anxious as those who must cope with more serious surgery. But when biopsies turn out to be unnecessary -- ordered due to false-positive mammographic interpretations -- the results can be troubling for both patients and radiologists.October 15, 2001BreastBreast cancer fears may nix follow-up screeningDoes anxiety about breast cancer screening -- or even a fatalistic attitude toward the disease -- affect whether a woman will show up for a mammography appointment? Two recent studies have yielded some answers.October 9, 2001CTCT dose study is good news for interventional radiologistsThe radiation exposure to staff and patients during three types of CT-guided procedures -- coagulation of osteoid osteoma, biopsy, and drainage -- is well within acceptable ranges, according to a study in The British Journal of Radiology.October 4, 2001Nuclear MedicineTherapy-eluding metastases caught with FDG-PETSome thyroid cancer patients with elevated serum thyroglobulin (Tg) levels may not benefit from conventional iodine therapy. However, FDG-PET can detect the tumors 131I imaging misses, according to French researchers.October 2, 2001Previous PagePage 78 of 100Next PageTop StoriesMedicolegalUnitedHealthcare alleges billing fraud in new RP lawsuitPass-through billing has come up again in a new lawsuit alleging RP funneled in-network claims through a "sham out-of-network entity."Molecular ImagingPET/MR enterography shows promise in Crohn’s diseaseAIPatient-facing AI shifts focus from reports to relationshipsMRIDTI-MRI shows childhood neglect's effect on the brain's white matterUltrasoundEcho images show consequences of steroid use among athletes
![Pittsburgh Compound B (PiB) PET distribution volume ratio (DVR) images were projected onto fsaverage surfaces from FreeSurfer and surface smoothed, with PiB (amyloid) slope maps created using ordinary least squares regression (time as only factor) and mixed effects models for 154 participants run at each vertex (P < .01; model: longitudinal Geriatric Depression Scale score estimated by amyloid slope × time + [sex + education + age] × time). This map visualizes the results of the linear mixed-effects models (t score of the main variable, amyloid slope × time) such that regions with a greater t score (red) represent areas in which greater depressive symptoms are associated with greater amyloid accumulation (amyloid slope).
