We evaluated myocardial perfusion using a rotational long axis view in clinical patients initially referred for pharmacokinetic stress testing and nuclear imaging. The results showed a clear distinction in perfusion reserve between normal and abnormal segments determined by SPECT, with mean flow reserve in normal regions twice as large compared to the regions with defects. Thus, we believe that rotational long axis myocardial perfusion imaging is not only technically easy to implement and provides improved apical and basal delineation, but also yields comparable stress perfusion results as conventional short axis imaging.
