New research presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) conference suggests that neuroreceptor differences in reactions to visual food cues between obese people and normal-weight individuals may improve the understanding of underlying mechanisms that contribute to obesity.

In a recent interview at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) conference in Chicago, Phillip Kuo, M.D., Ph.D, F.A.C.R., discussed the potential impact of urinary activity with positron emission tomography (PET) radiopharmaceuticals, and new phase 3 study data that found low urinary activity with the use of the flotufolastat F 18 injectable agent in patients with prostate cancer.

Dr. Nadel was announced as president of SNMMI for the 2023-2024 term at the 2023 SNMMI annual meeting taking place in Chicago.

A next-generation positron emission tomography/computed tomography (PET/CT) system, Biograph Vision.X, reportedly offers enhanced spatial resolution and a time of flight of 178 picoseconds.

The research, which garnered “Abstract of the Year” honors at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) conference in Chicago, demonstrates the potential of the targeted agent to significantly improve survival rates in AML.

The novel tracer improved both sensitivity and specificity in the study group, of which more than 50 percent were obese and typically more difficult to obtain high-quality imaging.

Kinetic modeling is important to understand how to obtain the best quantitative measurement of novel tracers in the organ of interest.

The newly launched Signa PET/MR Air device offers technological features that may bolster image quality and enhance diagnostic accuracy for diseases such as prostate cancer and Alzheimer’s disease.

The new portable ultrasound device, which is being showcased at the American Society of Echocardiography (ASE) conference, offers enhanced cardiac imaging as well as shared transducer interoperability and workflows with existing EPIQ CVx and Affiniti CVx ultrasound systems.

In multiple mammography datasets with the original radiologist-detected abnormality removed, deep learning detection of breast cancer had an average area under the curve (AUC) of 87 percent and an accuracy rate of 83 percent, according to research presented at the recent Society for Imaging Informatics in Medicine (SIIM) conference.
