Abstract：Objective To evaluate the value of dual energy CT (DECT) in the diagnosis of coronary stenosis and ischemic myocardium. Methods We searched PubMed, Embase, Wan Fang and CNKI databases for clinical studies of dual energy CT in diagnosis of coronary stenosis and ischemic myocardium. The literatures were screened by 2 independent reviewers and the effect index was extracted. Meta-Disc 1.4 and Stata 12.0 software are used for analysis. Results With respect to coronary artery, 320 samples and 943 coronary arteries were included. The sensitivity and specificity of DECT for the diagnosis of coronary artery stenosis were 0.89 (95%CI: 0.85~0.92) and 0.88 (95%CI: 0.85~0.90), respectively. AUC and Q* were 0.93 and 0.86, respectively. With respect to myocardial segment, 203 samples and 3246 myocardial segments were included. The sensitivity and specificity of DECT in the diagnosis of ischemic myocardium were 0.92 (95%CI: 0.90~0.95) and 0.96 (95%CI: 0.95~0.97) ,respectively. AUC and Q* were 0.99 and 0.95, respectively. Conclusions Available evidence suggests that DECT may provide a basis for the diagnosis of coronary stenosis and ischemic myocardium.
