Abstract
- Objective: To determine the accuracy of 64-slice computed tomography angiography (CTA) in the diagnosis of coronary artery lesions.<br />Methods: We retrospectively collected the coronary artery imaging data of 49 patients who underwent 64-slice CTA and conventional catheter-based selective coronary angiography (SCA) during July 2006 and May 2007. The CTA and SCA diagnosis were compared.<br />Results: The 64-slice CTA enabled the visualization of the entire coronary tree with diagnostic image quality in 46 of the 49 patients. The CTA had a sensitivity of 54.88%, 47.50% and 93.15%, and a specificity of 99.42%, 95.68% and 97.13% for detecting less than 50% stenosis, 50%-75% stenosis, and greater than 75% stenosis, respectively. The overall Pearson's correlation coefficient between the degree of stenosis detected by quantitative SCA and 64-slice CTA was 0.941.<br />Conclusion: 64-slice CTA is a good instrument for assessing coronary artery lesions.
