Shorter PET/MRI scans feasible for pediatric cancer patients
August 23, 2017 -- Researchers at Stanford University have developed a single-session PET/MR imaging protocol that reduces scan times for cancer patients and increases accuracy for evaluating chemotherapy-induced brain, heart, and bone abnormalities, according to a study published online August 4 in Radiology.  Discuss
AI predicts dementia years before symptoms occur
August 22, 2017 -- An artificial intelligence (AI) algorithm can recognize the signatures of dementia on amyloid PET scans two years before the onset of symptoms, according to research published online recently in Neurobiology of Aging.  Discuss
Hybrid modalities disappoint in bone metastases accuracy
August 21, 2017 -- Despite the apparent technological advantages of SPECT/CT, PET/CT, and PET/MRI, the three hybrid modalities do not perform appreciably better than planar bone scintigraphy in detecting and diagnosing bone metastases, according to a study published online August 10 in the Journal of Nuclear Medicine.  Discuss
JAMA: PET best option to diagnose ischemic heart disease
August 17, 2017 -- A head-to-head comparison to determine the most accurate modality for diagnosing myocardial ischemia has found that PET outperforms SPECT, coronary CT angiography, and hybrid variations of the three modalities in patients with suspected coronary artery disease, according to a study published online August 16 in JAMA Cardiology.  Discuss
PET links low serotonin levels to dementia
August 15, 2017 -- PET brain scans of people with mild cognitive problems show evidence of lower serotonin transporter levels, which can be an early indication of Alzheimer's disease or other dementias, according to a study published in the September issue of Neurobiology of Disease.  Discuss
Novel near-infrared agent could benefit lung nodule surgery
August 10, 2017 -- Researchers at the University of Pennsylvania are advancing lung cancer surgery by combining intraoperative molecular imaging with a novel near-infrared contrast agent and preoperative PET/CT scans to help surgeons better see and extract both obvious and hard-to-find tumors.  Discuss
New PET tracer could work well for prostate cancer
August 7, 2017 -- A new PET radiopharmaceutical based on carbon-11-labeled sarcosine could offer an alternative to choline-11-based PET for imaging patients with prostate cancer, according to a study published in the Journal of Nuclear Medicine.  Discuss
PET is center of attention at U.K. Alzheimer's conference
July 19, 2017 -- While PET can accurately detect or exclude Alzheimer's disease by imaging beta-amyloid plaques in the brain, the modality is underutilized in clinical care, according to research presented this week at the Alzheimer's Association International Conference in London.  Discuss
Radiotherapy boost based on PET not always helpful
July 13, 2017 -- Selectively increasing radiotherapy dose in tumor areas with significant uptake of the PET radiotracer F-18 fluoromisonidazole (FMISO) does not necessarily improve outcomes for non-small cell lung cancer patients, according to a phase II study published in the July issue of the Journal of Nuclear Medicine.  Discuss
PBS report targets price hike for V/Q radiotracers
June 30, 2017 -- Escalating costs for two radiopharmaceuticals used for ventilation/perfusion (V/Q) nuclear medicine scans in lung and kidney imaging are drawing the ire of pharmacies that prepare the materials for distribution to hospitals in the U.S., according to a June 30 report by PBS NewsHour.  Discuss
