Deep learning can estimate full-dose PET images from scans with significantly lower dosages, according to a new study in the Journal of Digital Imaging. The method may make performing PET scans safer and more affordable.

Using focused ultrasound, researchers from the Stanford University School of Medicine in California have developed a noninvasive method that helps deliver drugs to within a few millimeters of a targeted area of the brain, according to a study published online Nov. 7 in the journal Neuron.

After more than 30 years, a domestic supply of the radioisotope Iodine-131 (I-131) is now available for diagnostic imaging and thyroid cancer treatment.

Researchers from the Medical University of Vienna in Austria provided new guidance for selecting optimizing features from 18F-FDG-PET/CT studies—demonstrating feature variations can be minimized for selected image parameters and imaging systems, in a new study published Nov. 2 in the Journal of Nuclear Medicine.

Harvard University researchers used novel molecular imaging technology to make a first-of-its-kind “cellular atlas,” covering a key area in the brain to help study the genetic makeup and function of cells, according to research published online Nov. 1 in Science.

Clinical reporting strategies for PET/CT imaging exams in the oncology setting vary widely, according to results of a worldwide survey of clinicians published in the Journal of Nuclear Medicine. Thirty percent of respondents reported they were unaware reporting guidelines existed.

The Society of Nuclear Medicine and Molecular Imaging (SNMMI) issued an alert Wednesday, Oct. 31, warning members of an expected shortage of Mo-99 during the first-half of November, according to a news release.

An upcoming study will test a new imaging agent which allows visualization of human synapses, according to a news release. Results will inform a future trial designed to aid Parkinson’s patients.

Nuclear medicine departments are not communicating proper pre-scan instructions to diabetes mellitus management patients for optimizing fluoride-18 fluorodeoxyglucose (FDG) PET/CT imaging, according to new research published in the Journal of the American College of Radiology.

Pairing PET with CT achieved better diagnostic accuracy than temporal artery biopsy (TAB) in patients with newly suspected giant cell arteritis (GCA), according to research presented recently at the 2018 American College of Rheumatology (ACR)/ Association of Reproductive Health Professional (AHRP) meeting in Chicago.

The technique is able to map the structure of small organic molecules, such as pharmaceuticals and hormones, with electron diffraction imaging—commonly used to chart larger proteins, according to a report published Oct. 19 by Science Magazine.

Utilizing non-displaceable binding potential (BPND) quantification with 18F-Flutemetamol PET imaging can better assess amyloid pathology in elderly patients with low amyloid buildup compared to traditional standard uptake value ratio (SUVr), reported authors of an Oct. 12 study in the Journal of Nuclear Medicine.
