Three methods were investigated for predicting myocardial infarction size. /sup 99m/Tc stannous pyrophosphate scintigrams were obtained in six mongrel dogs 48 hours after coronary occlusion produced by ligating the left anterior descending coronary artery. Computer-aided processing of the images was used to calculate infarct projected area utilizing image processing and a Golay transform algorithm for detecting boundaries. The results suggest that infarct areas measured from anterior and left anterior oblique scintigrams can be used to calculate infarct weight using a linear relationship between scintigram infarct area and morphological infarct weight. Linear regression methods were used to determine the best linear relationship between the two sets of data. (auth)
