Quantification of regional myocardial blood flow using 13N-ammonia and reoriented dynamic positron emission tomographic imaging.

Abstract

Regional myocardial blood flow can be measured accurately and noninvasively from serially acquired and reoriented short-axis 13N-ammonia images, thus overcoming limitations inherent to the use of transaxially acquired images and permitting a more complete evaluation of regional blood flows throughout the left ventricular myocardium.
