Abstract

Objective To analyze the application value of elbow optimized position scanning of CT by comparison with routine CT scan. Methods Forty-eight patients with traumatic or non traumatic elbow injuries treated in our hospital between February 2015 and January 2016 were studied, and all patients underwent CT scanning. According to different scanning positions, they were divided into observation group (optimized position) and control group (normal position), 24 cases in each group. The image quality and X-ray radiation dose of once CT scanning were compared between the two groups. Results The excellent and good rates of CT scan image of elbow joint in the observation group (83.33%, 100.00%) were significantly higher than those in control group (25.00%, 79.17%) (P<0.05), the average X-ray radiation dose of once CT scanning in observation group (7.05±0.42) mGy was significantly less than that in the control group (10.53±1.37) mGy (P<0.05). Conclusion Compared with routine position scanning, the excellent and good rates of optimized position CT scan image of elbow joint are higher, and the X-ray radiation dose is less. It can be used as the preferred position of CT scan for patients with upper limb unable to raise traumatic elbow injury or non traumatic injury.
