PET with AV-1451 times tau deposits with Alzheimer's onset
September 7, 2017 -- Using PET with the novel radiotracer fluorine-18-AV-1451 that binds to tau deposits, Swedish researchers have linked certain regions of the brain with the early or late onset of Alzheimer's disease and its symptoms, according to a study published in the September issue of Brain.  Discuss
French raise alarm over smoldering blanket in PET/MRI
September 6, 2017 -- French researchers are alerting radiology facilities to an incident that occurred in their PET/MRI suite: Copper fibers in a blanket used to cover a patient began to heat up, causing the blanket to smolder and nearly catch fire, according to a case study published August 31 in Radiology.  Discuss
How ultrasound can trigger pain relief
September 5, 2017 -- Ultrasound can be used to release nerve-blocking agents contained in liposomes and relieve patients from pain. This would be an alternative to opioids and open up the possibility of a safer, on-demand, and personalized management of pain.  Discuss
Cambridge team moves ahead with multidimensional imaging
September 1, 2017 -- Sarah Bohndiek, PhD, and her colleagues at the U.K.'s University of Cambridge are on a mission to develop low-cost and nonionizing optical technology to improve early cancer detection. Bohndiek heads up an international team combining physicists, engineers, chemists, and molecular biologists.  Discuss
Hybrid modalities disappoint in bone metastases accuracy
August 25, 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 on 10 August in the Journal of Nuclear Medicine.  Discuss
JAMA: PET best option to diagnose ischemic heart disease
August 21, 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
Total-body PET scanner targets pediatric patients
August 11, 2017 -- A high-resolution total-body PET scanner, which will be the first of its kind in Europe, is being developed in Belgium. The machine -- dubbed PET20.0 -- will be completed by 2020, and will offer higher resolution scanning suitable for children.  Discuss
Dynamic PET tracks early treatment response
July 31, 2017 -- For head-and-neck cancer patients, dynamic PET can provide detailed characterization of the tumor microenvironment and a more accurate assessment of response, and also may be useful for cancers exhibiting a wide range of distribution volumes.  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
