Abstract: Objective To compare the value of dipyridamole 201T1 Single photon emission computed tomography (SPECT) myocardial imaging and exercise myocardial 99Tcm-MIBI SPECT imaging on diagnosing cardiac syndrome X.Methods Sixty-three patients with known cardiac syndrome X were divided into dipyridamole 201T1 SPECT myocardial imaging group (group 1,n = 35) and exercise myocardial 99Tcm-MIBI-SPECT imaging group (group 2,n = 28) and the diagnostic accuracy rates were compared.Results Thirty-one out of 35 cardiac syndrome X patients showed reverse redistribution in group 1 and the diagnostic accuracy rate was 89%.Positive test results were evidenced 24 out of 28 cardiac syndrome X patients in group 2 and the diagnostic accuracy rate was 87% (P > 0.05 vs.group 1).Conclusion The diagnostic accuracy rates of these two myocardial imaging methods were satisfactory and comparable on detecting cardiac syndrome X.
