Assessment of Coronary Flow Reserve by PET-H215O and FFR. Comparison With Dynamic Acquisition Using CZT Camera

Assessment of Coronary Flow Reserve by PET-H215O and FFR in Patients Suspected of Coroanry Artery Disease. a Comparative Study With Dynamic Acquisition Using CZT Camera and 99mcTc-mibi.

The study will assess coronary flow reserve by PET-H215O and FFR in patients suspected of coroanry artery disease. This a comparative study with dynamic acquisition using CZT camera and 99mcTc-mibi. 20 patients will have those measurements.
