| Research Abstract |
We developed the low radiation dose cardiac imaging method by "single-beat scan with prospective ECG-gating" using a 320-detector row CT. The diagnostic accuracy of this method for coronary in-stent restenosis was 100% of sensitivity, specificity 87.8% in consecutive 102 patients, and the effective radiation dose was approximately 4.8 mSv. We could reduce approximately 32% of radiation dose if we use the adaptive iterative reconstruction method. We tried the subtraction coronary CT using this technique for the patients who had severe coronary artery calcifications.
