Abstract:

97 cases of transmural myocardial infarction(MI)and 10 cases of non-transmural MI were studied by radionuclide SPECT myocardial imaging using ^99mTc-CPI or MIBI and com-pared with the results of EKG.Our study showed that the amount of abnormal segments was 167 and 143 in SPECT myocardial imaging and EKG respectively in transmural MI,so the detecting ability of SPECT was higher.In the 97 cases of transmural MI,84 cases showed significantly abnormal using SPECT,13 cases showed abnormal.In the 10 cases of non-transmural MI,5 cases showed abnormal,4 cases suspicious abnormal and 1 cases was normal.If the significant abnormal manifestation was used as the diagnostic criterion,the de-tectable rate using SPECT for transmural MI was 86.6%,and 0 for non-transmural MI 0.
