Abstract:
Objective To investigate the diagnostic value of myocardial perfusion imaging(MPI) and multislice spiral computed tomography(MSCT)for coronary artery disease(CAD).Methods Coronary angiography (CAG),MPI and MSCT were performed in 43 patients (36 with suspected,7 with known CAD).MPI examinations were evaluated semiquantitatively by agreement of two experienced observers.SDS (summed difference score)>1 Was defined as reversible ischemia.and each myocardial segment was allocated to the territory of one of the coronary arteries.The MSCT results were defined as positive when steneses(≥50%) were found in one main vessel or its main branch vesseL CAG results served as"gold standard".The diagnostic values of MPI andMSCT for CAD were compared respectively on patient basis and on vessel basis.Results On pailent basis,the sensitivity.specificity and accuracy of MPI for diagnosing CAD were 79.17%.84.21% and 81.40% which were similar as those of MSCT:83.33%.89.47% and 86.05%(all P>0.05).On vessel basis.the sensitivity.soecificity and accuracy of MPl were 53.19%.89.02%and 75.97%which were also similarto fhore of MSCT:70.21%,95.12%and 86.05%(all P>0.05).Condusion The non-invasive MPI and MSCT provide satisfactory and similar diagnostic infornmtion on diagnosing CAD.
