A tumor segmentation software dubbed single-click ensemble segmentation (SCES) is advancing the definition and delineation of a wide range of cancerous lesions past manual labor and into the realm of high-tech automation. 

Breast cancer tumors often express vascular endothelial growth factor (VEGF)-A and a method of detection involving PET and the monoclonal antibody tracer Zr-89 bevacizumab is showing promise for the assessment of early to late stage primary malignancy, according to a study published May 7 in the Journal of Nuclear Medicine.

Simultaneous PET/MR broke additional ground toward clinical use by showing technical success and potential clinical merit for FDG PET/MR detection of ischemic heart disease, according to a study published May 7 in Radiology.

A multi-step study has determined that SPECT is a superior method of ventilator-perfusion (V/Q) imaging for the diagnosis of pulmonary embolism (PE) and also has indicated an optimal imaging protocol for its application, according to the second phase of the study published May 1 in the Journal of Nuclear Medicine.

The current climate of Parkinson’s research is much like it was for Alzheimer’s disease before there was a clear way forward toward pathological detection. Complex clinical features, genetics and molecular drivers of the disease in all its various forms make it exceedingly difficult to standardize research and therefore screening and diagnosis, but a new framework for research is being presented, according to a perspective piece published online April 11 by The Lancet.

Baxter announced results of its Phase III clinical study of immunoglobulin (IG). In the randomized, double-blind, placebo-controlled, multi-center trial, IG did not meet its co-primary endpoints of reducing cognitive decline and preserving functional abilities in patients with mild to moderate Alzheimer's disease after 18 months of treatment. Given the findings, Baxter said it will re-evaluate its approach for its Alzheimer’s program.

Many older patients undergoing an exercise stress test may not need molecular imaging to provide a clear picture of cardiovascular health. Evidence suggests that SPECT MPI may not provide any additional information for those who are nimble enough to reach a certain level of exertion and show no signs of CAD or cardiovascular distress. These and similar findings point to potential radioisotope injection guidelines to reduce radiation dose and cost of healthcare for these patients, according to research presented at the International Conference on Nuclear Cardiology and Cardiac CT, held May 5 to 8 in Berlin.

MILabs, B.V. the Netherlands‐based innovator and manufacturer of pre‐clinical SPECT/PET/CT imaging devices used in biomedical research, today announces the release of the new mini product family ‐ an easy‐to‐use series of benchtop SPECT and PET imagers for small animals that combine simplified workflow, compact dimensions and affordable pricing to bring high‐performance SPECT/PET within everyone’s reach.
