Preserved diagnostic performance of dual-source CT coronary angiography with reduced radiation exposure and cancer risk.

摘要: Purpose: To evaluate the effects of standard and optimal electrocardiographic (ECG) pulsing on diagnostic performance, radiation dose, cancer risk in symptomatic patients a “real-world” clinical setting. Materials Methods: The institutional review board approved study, all gave informed consent. Dual-source computed tomographic (CT) coronary angiography was performed 436 (301 men, 135 women; mean age, 61.6 years ± 10.6 [standard deviation]; age range, 23–89 years) referred for conventional angiography. Standard ECG 327 109 patients, respectively. performance dual-source CT detection significant stenosis (≥50 luminal diameter reduction), with quantitative as reference standard, reported sensitivity, specificity, positive negative predictive values, likelihood ratios. effective dose...
