PDFAbstract
Objective To evaluate the clinical value of the myocardial perfusion imaging dual-source CT (DSCT) dual energy, in the comparison of SPECT. Methods 18 cases of clinically suspected or known coronary artery disease were of collected. Then the patients underwent the myocardial perfusion imaging of DSCT and resting /loaded technetium99m SPECT.The imaging findings then were analyzed further. Results In 18 patients with DSCT dual energy myocardial perfusion imaging, 14 cases were positive, when 4 cases were negative. Compared with SPECT examination, the same cardiac perfusion defect of 14 positive cases were found in SPECT as in DSCT. Among 4 negative cases of DSCT examination, loaded SPECT detected myocardial ischemia in 1 case. Detection rates of cardiac perfusion defect between DSCT with SPECT showed no significant difference(P>0.05). Conclusion The myocardial perfusion imaging in DSCT dual energy possess the similar capability in myocardial perfusion defects with SPECT, and manifest great diagnosis value for coronary heart disease.
