Abstract: Objective To study the feasibility of dual-source CT with dual-energy imaging based on single contrast enhancement. Methods The clinical data of 60 cases of patients who underwent dual-energy CT (DECT)examination of the heart in our hospital were analyzed.statistically.Results The success rate of 60 cases were 100% for displaying all 600 coronary artery segments at all stages.The total mean score of image quality was 4.68 ±0.57,and the good image rate reached 95%.6 cases of patients who ac-cepted DSA examination were unanimous with DECT findings;In 6 cases of patients who accepted SPECT examination,60 segments were no perfusion abnormalities,but DECT iodine figures of 54 segments were normal,and 6 segments showed perfusion defect. Conclusion DECT with dual-energy imaging based on single contrast enhancement can get excellent coronary and myocardial perfu-sion imaging in the circumstance of appropriate heart rate,which has some potentials for clinical application.
