Eric Barnes[email protected]BreastBetter liver transplant decisions; hope for mammography screeningAugust 18, 2010CTPerfusion CT finds subtle liver toxicity in chemotherapy patientsA new study from China found that perfusion CT can detect and quantitatively assess microvessel changes associated with liver toxicity in chemotherapy patients. The results could help noninvasively assess early liver damage in cancer patients while obviating the need for a separate scan.August 17, 2010CTSHAPE II task force revising cardiac risk guidelinesThe Houston-based Society for Heart Attack Prevention and Eradication (SHAPE), which wants to scrap population-based cardiac risk assessment in favor of imaging-based evaluation of each individual, said it will release new guidelines at the November American Heart Association meeting in Chicago.August 16, 2010CTCoronary calcium usually ignored on chest CTRadiologists often fail to report coronary calcium detected on chest CT scans. By ignoring it, they miss not only the chance to detect potentially serious heart disease, but an important opportunity to evaluate the chances of lowering a patient's risk of heart attack with treatment.August 11, 2010CTClinical study backs newly cleared VC CAD softwareBacked by a study that shows high sensitivity and specificity in patients, a new computer-aided detection (CAD) scheme for virtual colonoscopy was approved last week by the U.S. Food and Drug Administration.August 9, 2010CTLack of virtual colonoscopy coverage a barrier to screeningA survey of primary care patients who were offered but did not undergo colon cancer screening found that more than four-fifths would be willing to undergo virtual colonoscopy -- but not if they had to pay the entire cost out of pocket.August 8, 2010CTSoCal hospitals say patients got too much CT radiationTwo more hospitals in Southern California have admitted that patients undergoing perfusion CT brain scans last fall received excessive radiation doses, just as legislation that would require dose levels to be displayed on CT scanners won a vote in the state Assembly.August 5, 2010Nuclear MedicineCombined PET/CT CAD improves lung nodule detectionResearchers in Japan have developed computer-aided detection (CAD) software that detects lung nodules in PET/CT images of lung cancer screening patients. Applying a combined CAD system to both modalities instead of CT or PET alone nearly doubled the number of solitary pulmonary nodules detected.August 5, 2010InterventionalHallan alta taza de cataratas en cardiólogos intervencionistasUna nueva investigación de cardiólogos intervencionistas y enfermeras en Malasia revela una taza de incidencia de cataratas cinco veces más elevada que en el grupo de control, la cual implica que los límites de dosis de radiación son demasiado altos para proteger al personal.August 4, 2010Digital X-RayHigh cataract rates found in interventional cardiologistsA new study of interventional cardiologists and nurses in Malaysia found five times the rate of cataracts in the group compared to controls, suggesting that current radiation protection thresholds may be too high to protect providers from harm.August 4, 2010Previous PagePage 120 of 258Next PageTop StoriesWomens ImagingWomen's Imaging MinnieCast, Episode 2: Risk-based vs. annual mammography screening, part 1Vilert Loving, MD, from Ochsner Health and the SBI discusses breast cancer screening based on annual mammography versus risk.Digital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsMRI3D MRI technique helps plan treatment for pediatric heart conditionsWomens ImagingCould AI scoring help with managing DCIS?CTClinicians, beware: CT diagnostic accuracy varies by adnexal lesion type

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).
