[Clinical value of dual-source CT in evaluating coronary artery disease].
OBJECTIVE
To analyze the clinical value of dual-source CT (DSCT) in the diagnosis of coronary artery disease.


METHODS
Fifty-five patients with suspected coronary heart disease underwent both DSCT coronary angiography (DSCTCA) and selective coronary angiography (CAG) examination, and the diagnostic sensitivity, specificity and accuracy of the DSCTCA was evaluated.


RESULTS
The sensitivity, specificity, positive and negative predictive value, and accuracy of DSCT in the diagnosis of coronary heart disease were 97.7%, 72.6%, 93.5%, 88.9% and 92.7% by the number of patients, respectively; by calculating the coronary arteries, the sensitivity, specificity, positive and negative predictive value, accuracy were 94.9%, 95.8%, 92.5%, 97.1%, 95.5%, respectively. According to the lesion segment, these values were 88.2%, 96.9%, 90.5%, 96.1%, 94.7%, respectively. DSCTCA showed no significant difference from CAG for a diagnostic purpose, nor did their vessel sensitivity, specificity, positive and negative predictive value, and accuracy in different coronaries differ significantly.


CONCLUSIONS
DSCT has a diagnostic accuracy of coronary heart disease close to that CAG and can on some occasion serve as an alternative to CAG in the screening of coronary artery disease.
