tokens: In the clinical study , the defect size shown by BMIPP imaging was greater in anterior than in inferior infarcts ( p < 0 . 001 ) and correlated well with the risk area revealed by contrast ventriculography ( r = 0 . 80 , p < 0 . 0001 ) CONCLUSION : The above preliminary data , admittedly from a small group of patients , suggest that tomographic BMIPP imaging provides an accurate quantification of defect size by means of a simple threshold technique and , in the subacute phase , permits determination of the amount of myocardium at risk after acute myocardial infarction .
