Cardiac Computed Tomography Coronary Angiography Post Non-diagnostic or Equivocal Myocardial Perfusion SPECT
Journal Title: International Journal of Radiology and Radiation Oncology - Year 2017, Vol 3, Issue 1
Abstract
Background: Myocardial perfusion single- photon emission computed tomography (MP-SPECT) plays a key role in the management of patients with known or suspected coronary artery disease (CAD). However, Infrequently, MP-SPECT is non-diagnostic or equivocal. Computed Tomography coronary angiography (CTCA) has high diagnostic accuracy and excellent negative predicted value .The goal of the study is to investigate the diagnostic value of CTCA after non-diagnostic, equivocal, and or borderline abnormal MP-SPECT. Methods: 64 patients were with suspected CAD were enrolled in this study, the mean age was 51 ± 24 years, 36 (56%) male and 28 (44%) female. MP-SPECT result was classified into 3 categories: Probably normal or probably abnormal, Abnormal function and normal myocardial perfusion, and equivocal or non-diagnostic.
