Why 13N-NH3


Why 13N- Ammonia

The fast track to accurate diagnosis

13N-Ammonia is an effective diagnostic tool that improves patient management by
accurately detecting coronary artery disease (CAD) due to its short positron range, high sensitivity, and high first-pass extraction and retention properties in the myocardium. Increasingly preferred by leading cardiac imaging institutes, 13N-Ammonia is experiencing rapid adoption for cardiac PET imaging, as it provides diagnostic studies of consistently high-quality, regardless of patient size or gender.
