Podcast: Telltale signs your MRI safety standards are inadequate
RET-targeted PET tracer highlights neuroendocrine prostate cancer tumors. Representative PET imaging shows strong tumor uptake of the RET-binding peptide tracer [⁶⁸Ga]Ga-DOTA-RET-L7 in a neuroendocrine prostate cancer (NEPC) model, supporting highly specific, high-contrast detection.

ASCO: Use of GLP-1 drugs linked to lower breast cancer cases
A 68Ga-RCC78 PET scan (C) of a patient four years post-radical right nephrectomy. During follow-up, new nodules were detected in the left adrenal gland and kidney. CAIX-targeted scan clearly visualized metastatic lesions in the mediastinum, pancreas, adrenal gland, and kidney (SUVmax > 30), demonstrating the tracer's ability to maintain high tumor uptake despite significantly reduced abdominal background.

SNMMI: PET tracer that detects deep vein thrombosis wins Image of the Year
By Will Morton
F-18 GP1 is derived from elarofiban and selectively binds to glycoprotein IIb/IIIa receptors on activated platelets.
June 1, 2026
(Left) F-18 GP1 PET/CT images from a 75-year-old woman show multiple blood clots in the deep veins of the left leg (from the thigh to the calf), as well as several clots in the right calf. Venous ultrasound confirms blood clots in left thigh, knee and calf veins. PET/CT also detects clots in both lungs, which are confirmed by contrast-enhanced CT image. (Right) 18F-GP1 PET/CT images from a 70-year-old woman show widespread blood clots throughout the body. In addition to clots in the deep veins of both legs and the arteries of both lungs (A), the scan also detected unexpected clots in several other areas, including blood vessels near the skull/head (B), spine (C), heart (D), and pelvis (E). Further evaluation revealed that the patient had antiphospholipid syndrome, an autoimmune condition that increases the risk of abnormal blood clot formation.
