Abstract Objective: To evaluate the clinical value of multidetector computed tomographic angiography(MDCTA) in the judgement of in-stent restenosis(ISR) after coronary stenting. Materials and Methods: Thirty-four patients who had been performed coronary stenting with 65 stents were included in the study. All the patients were examined by 64-row MDCTA and invasive coronary angiography for evaluating ISR after coronary stenting. Results: These findings resulted in a sensitivity of 82.4%, specificity of 97.9%, false positive rate of 2.1%, false negative rate of 17.6%, coincidence rate of 93.8%, positive predictive value of 93.3%, and negative predictive value of 94.0%, respectively. Conclusion: MDCTA seems to be an effective imaging modality in identifying ISR and can evaluate ISR semiquantitatively.
