Study evaluates new PET radiotracer in detecting small blood clots

German researchers found that PET with the breakthrough small molecule radiotracer F-18-GP1, which binds to GPIIb/IIIa receptors involved in platelet clumping, exhibited rapid blood clearance and identified small arterial and venous clots, emboli and endothelial damage in the brain of a monkey model. The findings, presented at the SNMMI Annual Meeting and published in the Journal of Nuclear Medicine, suggest the radiotracer may bolster the accuracy of anatomic localization and information on clot growth or embolization risk and result in clinical intervention changes for patients, said researcher Dr. Andrew Stephens.
