A German-led research team has developed a new nuclear medicine imaging technique that outperforms standard tumor imaging by targeting cancer-associated fibroblasts (CAFs), according to research published in the September issue of the Journal of Nuclear Medicine.

Using patient-specific body weight-based protocols during whole-body fluorodeoxyglucose (18F-FDG) PET/CT can greatly reduce radiation dosage while maintaining image quality, according to authors of an Academic Radiology study.

For patients with Alzheimer’s disease, amyloid PET imaging can improve diagnosis, diagnostic confidence and treatment, according to a JAMA Neurology study. The method is beneficial whether results are positive or negative.

Aetna announced, Thursday, Aug. 16, it will expand its coverage of the PET tracer gallium-68 (Ga-68) dotatate, according to a Society of Nuclear Medicine and Molecular Imaging (SNMMI) release. The radiopharmaceutical is now considered “medically necessary.”

Extending PET acquisition time during PET/MRI for rectal cancer staging increases identified lymph nodes and has no impact on scan time, reported authors of a recent American Journal of Roentgenology study.

Yale University researchers have developed a new approach that can provide more information about molecular function inside the brain through linking gene expression patterns to brain signals captured by MRI-derived T1-weighted/T2-weighted mapping.

A new molecular imaging method developed by engineers from Lehigh University in Bethlehem, Pennsylvania, may improve cancer screening and treatment monitoring through high-frequency microwaves.  

The Society of Nuclear Medicine and Molecular Imaging (SNMMI) released its list of members recognized for outstanding dedication and service in the fields of nuclear medicine and molecular imaging.  

In the face of a challenging nuclear medicine (NM) landscape, defined by declining reimbursement and disruptive technology, a group of radiologists set out to determine work patterns of self-identified NM specialists.

Production of technetium-99m (Tc-99m) is expected to resume soon at the Australian generator that was forced to shut down in June, according to the Australian Nuclear Science and Technology Organization (ANSTO).

Yale University researchers have discovered a new PET imaging method that measures beta-cell mass which could improve monitoring, according to research published online in the August issue of the Journal of Nuclear Medicine.  

Dutch researchers utilized a PET tracer to distinguish differences in estrogen receptor (ER) expression in metastatic breast cancer patients, according to a recent Journal of Nuclear Medicine study. Findings may enhance treatment for these patients.
