Abstract Objective: To evaluate the value of 640-slice MDCT in assessment of left ventricular regional wall motion (LVRWM), using 2D-echocardiography as the reference standard. Methods: Sixty-two patients undergone 640-slice MDCT and 2D-echocardiography were evaluate. The motion of 1054 segments was visually assessed by two radiologists with a 3-piont scale using a 17-segment model. A separate reader assessedLVRWM of 1054 segments on 2D-echocardiography using the same criteria as did in the MDCT. Results: LVRWM abnormalities were detected in 196 and 190 segments on MDCT and 2D-echocardiography respectively, of which 58 and 50 segments were hypokinesis or akinesis, 138 and 140 segments were mild or moderate hypokinesis. The sensitivity, specificity and accuracy of MDCT for diagnosing abnormal segment wall motion were 94.0%, 77.0%, and 91.0% respectively. The data of wall motion and wall thickening of each LV segment were also acquired. Conclusion: The value of 640-slice MDCT in qualitatively assessment of LVRWM is significant, and it shows great potential in quantitatively assessment of LVRWM.
