PDFAbstract
Objective To assess the difference between computed tomography coronary angiography (CTCA) and different types of multislice spiral computed tomography perfusion imaging (MSCTP) combined with CTCA in the diagnosis of coronary artery stenosis. Methods A total of 80 cases of clinical suspected coronary heart disease patients were included in this study, CTCA and cornary angioiography (CAG) were performed in all patients. Of the 28 accepted multislice spiral computed tomography perfusion imaging (MSCTP) under adenosine stress. The diagnostic accuracy of variours MSCTP myocardial imaging were compared with the CTCA, and CAG were regarded as the "gold standard". Results The accuracy rate of CTCA combined MSCTP were higher than individual CTCA (76.3%) examination, while MSCTP under adenosine stress(89.3%) were higher than the first-pass myocardial perfusion group (80.0%) ,which similar to resting myocardial perfusion group (82.1%). Conclusion Combined CTCA with MSCTP improve the diagnostic accuracy in coronary artery stenosis.
