Abdominal pain and cramping. A perfusion test tells your doctor how your heart is performing and whether it is getting enough blood. This may be achieved with improvement in coincidence time resolution (lower than 100 ps) through new PET detector designs, and some day even crossing the 10 ps, which will increase the performance of time-of-flight PET dramatically, resulting in a better signal-to-noise ratio of the activity measurement (e.g., F-18 Flurpiridaz), improving the reconstruction process and rendering quantifying the endocardial-to-epicardial distribution of myocardial blood flow achievable and attainable.
