The results hint that Amyvid could be useful beyond its core indication of detecting beta-amyloid deposits in the brain.July 15, 2013Nuclear MedicineFlorbetaben-PET detects amyloid in people with Down syndromeA new study using PET with a florbetaben radiopharmaceutical shows how people with Down syndrome begin to accumulate beta-amyloid deposits in their brains in their early 40s, putting this population at greater risk for the early onset of cognitive impairment.July 10, 2013Nuclear MedicineFDG-PET, DWI-MRI help predict osteosarcoma chemo responseCombining FDG-PET/CT and diffusion-weighed MRI (DWI-MRI) may be useful for predicting the histologic response of osteosarcoma to neoadjuvant chemotherapy, according to a study published in the July issue of the Journal of Nuclear Medicine.July 10, 2013MRIHalf dose of MRI contrast feasible for rheumatoid arthritisA half dose of the MRI contrast agent gadobenate dimeglumine provides just as much relevant diagnostic information as a full dose in 3-tesla imaging of patients with early rheumatoid arthritis, according to a study published in the July issue of Radiology.July 8, 2013Nuclear MedicineCMS again withholds endorsement of PET beta-amyloid imagingFor the second time this year, the U.S. Centers for Medicare and Medicaid Services (CMS) has stopped short of fully endorsing PET beta-amyloid imaging for Medicare beneficiaries with dementia or neurodegenerative disease.July 2, 2013Nuclear MedicineNaF-PET/CT beats scintigraphy, SPECT/CT for bone metastasesSodium fluoride (NaF) PET/CT provides greater sensitivity and specificity for the detection of bone metastases than planar bone scintigraphy and SPECT/CT, according to a new pilot study from Copenhagen University Hospital.June 30, 2013Nuclear MedicineNuclear medicine facilities adhering to radiation dose standardsNuclear medicine facilities in the U.S. appear to be getting the message about controlling radiation dose. A new survey of more than 300 SPECT and PET centers found that most are keeping dose levels within generally accepted levels.June 25, 2013Nuclear MedicineSurvey finds U.S. installed base of gamma cameras is agingThe average age of gamma cameras at nuclear cardiology labs in the U.S. grew by two years between 2009 and 2011, according to a survey from the University of Missouri. The authors believe that economics is playing a larger role in whether a facility can afford to employ the latest imaging technology.June 23, 2013Nuclear MedicineResearch falls short in backing PET for cancer surveillancePublished research isn't sufficiently showing the effectiveness of PET and PET/CT for the surveillance of several cancers, according to a June 17 article in the Journal of Nuclear Medicine. Studies lack standard definitions for surveillance, use different scanning protocols, and have inconsistent reports of test accuracy.June 20, 2013Previous PagePage 129 of 239Next PageTop StoriesMolecular ImagingExperts issue appropriate use criteria for molecular breast imagingThe criteria offer use scenarios for technetium-99 (Tc-99m) sestamibi-based gamma camera imaging of the breast.MRIfMRI: Cognitive behavioral therapy positively affects the brainPractice ManagementPost Cures Act, outpatients access radiology reports fasterMRIMRI may help guide brachial plexus surgeryAIShould hospitals pursue local domain LLM adaptation for radiology reports?
