Novel PET agent could sniff out neurological disease
January 24, 2017 -- Backed by previous research suggesting that losing one's sense of smell can be a sign of neurodegeneration, researchers are developing a novel PET imaging agent that targets olfactory neurons to assess the extent of disease, according to a study published online January 23 in the Journal of Clinical Investigation.
PET/CT CAD finds common spinal metastases
January 23, 2017 -- A new multipurpose computer-aided detection (CAD) algorithm was able to detect and characterize different kinds of spinal metastases in PET/CT images automatically and accurately, say researchers from two U.S. institutions. The fully automated system could help doctors diagnose and manage patients with the most common musculoskeletal metastases.
Are radiation dose guidelines scaring patients?
January 13, 2017 -- Are guidelines urging healthcare practitioners to reduce radiation dose when imaging patients simply inducing radiation phobia for procedures that have little to no health risk? That's the provocative stance of a new article published in the January 2017 issue of the Journal of Nuclear Medicine.
PET/CT may have found cardiovascular event trigger
January 12, 2017 -- PET/CT scans have identified activity in a stress-related structure in the brain that could be linked to an increased risk of cardiovascular disease, according to a study published online January 11 in the Lancet.
PET/CT remains best option for head, neck cancer
January 9, 2017 -- While PET/MRI shows great promise in a multitude of clinical applications, German researchers have found that the hybrid modality's performance in evaluating head and neck cancer appears no better than that of tried-and-true PET/CT.
3D-printed kidney phantom advances SPECT/CT calibration
December 12, 2016 -- German researchers have developed a low-cost 3D printing technology that can be used to create patient-specific organ models of varying sizes and shapes, according to a study published in the December issue of the Journal of Nuclear Medicine.
PiB-PET could open window on common meningiomas
December 9, 2016 -- With its ability to achieve a high level of specificity, the combination of carbon-11-labeled Pittsburgh Compound B (PiB) with PET imaging is showing early promise in distinguishing meningiomas from other intracranial tumors, according to a study presented recently at RSNA 2016.
PET/MRI head scans reveal important incidental findings
November 30, 2016 -- CHICAGO - Adding a scan of the entire head to a routine whole-body PET/MRI protocol reveals a significant number of incidental findings in the brain in asymptomatic cancer patients, according to a study presented on Wednesday at RSNA 2016.
