- W2359643939 abstract "Objective According to the definition of Q-angles,we combined the volume rendering(VR)techniques of MSCT with image workstation to reconstruct the anatomic relationship between quadriceps femoris and patella integrallty.The measurement of Q-angles was done on the reconstructed 3D images,and accurate data was obtained to guide clinical treatment.Methods From 2006 to 2008,62 patients with patellar instability including 21 males and 41 females were examined with multi-slice spiral CT scan before operation,age ranged from 14 to 45 years,mean age was 22.1 years.We composed the VR protocol ourselves.We measured the Q-angles on the reconstructed images.The acquired data was compared with the data obtained by body surface measurement with paired T-test.Results Among the Q-angles acquired with Volume Rendering techniques of MSCT,the average value of the Q-angles of 62 uninjured sides(±s)was 12.5°±4.8°.Among the Q-angles obtained by body surface measurement,the average value of the Q-angles of 62 uninjured sides(±s)was 14.5°±5.5°.The difference between these two methods showed statistical significance(P0.05).Conclusion Comparing with body surface measurement,the data of Q-angles obtained by the method of VR techniques of MSCT was more accurate and credible.The data has satisfactory consistency,which offer exact image data for surgical operation plans and are in favor of following up." @default.
