Abstract

Objective: To discuss the clinical value of changing imaging position and CT attenuation correction in the differentiation of inferior-posterior myocardial artifact. Methods: Changing imaging position and performing CT attenuation correction in the process of myocardial perfusion imaging were performed in 54 normal persons, and the normalcy rate, Kappa, accumulative score, count percent in different region of myocardium were calculated respectively. Results: The normalcy rate, Kappa, accumulative score were significantly improved by the way of changing imaging position and performing CT attenuation correction(P<0.05). Conclusion: The artifacts in the inferior-posterior myocardium can be efficiently differentiated by the way of changing imaging position and performing CT attenuation correction, and the diagnostic accuracy is significantly improved.
