LOUIS - With a quarter of a million hip and knee replacements performed annually in the United States, accurate assessment of prosthesis-related infections is more vital than ever. Some investigators see great promise for FDG-PET in this role, while others see a major problem with poor specificity.June 4, 2000Clinical NewsMidwestern radiologists play hardball to ensure clinicians meet Medicare's rulesAfter finding that diagnoses and indications were missing for nearly one-third of its imaging exams, the Indiana University Medical Center tried sending reminders, returning requisitions, and even turning away patients.June 1, 2000CTSlow image reconstruction continues to hamper virtual colonoscopyCreating virtual endoscopy images from multislice CT data is an effective but time-consuming way to examine the abdomen and the colon, according to German researchers reviewing the pros and cons of this technique.May 29, 2000Practice ManagementStandardized reporting systems would aid competency reviews in radiology, researchers sayA review of chest x-ray readings at the University of Michigan also reconfirms the value of subspecialization in reducing misdiagnosis.May 23, 2000CTEye of the beholder: institutions disagree over scan quality in weight-dosed contrast CTVarying the dosage of low osmolality contrast media for routine abdominal CT based on patient size can provide optimized contrast delivery for a minimal cost increase, according to a multi-institutional study.May 21, 2000BreastBetter detection, better drugs lead to sharply lower breast cancer mortalityMortality rates from breast cancer have plummeted thanks to better treatment methods, according to a letter from British researchers published in the latest issue of The LancetMay 18, 2000Clinical NewsWell-diluted contrast media is safer for colon evaluations in infantsWhen used in low concentrations, nonionic, water-soluble contrast agents do not adversely affect colon cells in pre-term infants, according to Austrian radiologists.May 17, 2000BreastMisdiagnoses, lack of supervision, and poor communication land radiologists in courtRadiologists have the dubious distinction of being the most frequent defendants in malpractice lawsuits, particularly for the misdiagnosis of breast cancer, with the payout to a plaintiff averaging more than $200,000.May 16, 2000Practice ManagementOttawa Knee Rule cuts costs when institutions maintain high sensitivityThe Ottawa Knee Rule and a near perfect sensitivity rate go hand-in-hand if an institution hopes to minimize costs by using the rule, according to a team of researchers from Dallas and Atlanta.May 14, 2000CTPass on the Rolaids: CT scans for appendicitis stump radiologistsWASHINGTON, DC - A lack of specific training led to misdiagnoses by radiology residents reading appendiceal CT scans, while over-the-counter antacids caused misreadings even among experienced radiologists, according to presentations at the American Roentgen Ray Society meeting.May 10, 2000Previous PagePage 93 of 100Next PageTop StoriesMolecular ImagingPET reveals mechanism underlying brain fog in long COVIDBrain regions where C-11 K-2 radiotracer was increased were negatively correlated with long COVID patients’ performance on cognitive tests.MRIMRI finds that brain shape changes may be associated with dementiaWomens ImagingFalse-positive DBT findings differ between AI, radiologistsPractice ManagementWhat is the real impact of the 2025 MPFS Proposed Rule on radiology practices?Sponsor ContentDigital Innovations Shaping the Future of Radiology
![Coronal and axial slice of the average cortical F-18 MK-6240 SUVR [standard uptake value ratio] image for each study population. SUVR images were corrected for partial volume effects and masked with the gray matter mask used for volume of interest delineation. Overall tau accumulation is comparable between the late-life depression (LLD, middle column) and non-depressed cognitively unimpaired comparison (HC, left column) groups, while abnormal tau accumulation, which is most pronounced in the mesial temporal lobe, can be seen in the mild cognitive impairment due to Alzheimer's disease group (right column).
