Wayne Forrest[email protected]Nuclear MedicineStart-up Brain Biosciences advances compact PET scannerStart-up firm Brain Biosciences is hoping to ride the wave of interest in PET scanning for Alzheimer's and other brain diseases by commercializing CerePET, a portable PET scanner designed to offer more cost-effective neuroimaging than whole-body scanners.January 22, 2014Nuclear MedicineSoftware adds diagnostic value for heart disease patientsDutch researchers have developed 3D visualization software that fuses anatomical and functional data into a single image. They believe the fused images make it easier to diagnose cases of coronary artery disease, according to a paper in the January issue of the Journal of Nuclear Medicine.January 20, 2014MRITriaging hearing loss patients can help save on MRI scansUsing less-complex MRI scans to triage patients with hearing loss, while reserving comprehensive MRI exams for those with pathology, can save money without affecting diagnostic efficacy, according to research published in the January issue of the American Journal of Roentgenology.January 9, 2014Nuclear MedicinePET with F-18 FDOPA differentiates brain lesionsPET with the radiopharmaceutical fluorine-18 fluorodopa (F-18 FDOPA) can help differentiate recurrent or progressive brain metastases from late or delayed radiation injury, according to a study published in the January issue of the Journal of Nuclear Medicine.January 8, 2014MRIMRI technologies land on ECRI's 2014 watch listNonprofit research firm ECRI Institute has included MR-guided focused ultrasound and the integration of MR images in radiation therapy on its technology watch list for the coming 12 to 18 months.January 6, 2014MRI4T fMRI sheds light on brain activity in early Alzheimer'sA new study by Canadian researchers illustrates how perfusion-based functional MRI (fMRI) with a 4-tesla arterial spin labeling protocol can be used to measure brain activity in people with early-stage Alzheimer's disease while they perform memory tasks.December 23, 2013Nuclear MedicinePET/MRI offers details in acute myocardial infarction casesGerman researchers have concluded that simultaneous PET/MRI for patients with acute myocardial infarction is feasible after finding "good concordance" in a comparison of PET and MR images. The study was presented at the RSNA 2013 meeting earlier this month.December 19, 2013MRIAuntMinnie.com MRI InsiderDecember 18, 2013Nuclear MedicineAuntMinnie.com Molecular Imaging InsiderDecember 16, 2013MRIStudy links gadolinium MR contrast to brain abnormalitiesJapanese researchers have found a connection between gadolinium-based MRI contrast and abnormalities in two regions of the brain, which could represent a reaction to gadolinium's toxicity, according to a study published online December 17 in Radiology.December 16, 2013Previous PagePage 120 of 239Next PageTop StoriesDigital X-RayChest x-rays reveal atherosclerosis in patients undergoing amputationsLower limb amputation is an increasingly common major complication of advanced peripheral arterial disease and diabetes mellitus.MRI3D 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 typePractice ManagementRadiology coding update for 2026
![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).
