Abstract:
PURPOSE: To find out the best imaging parameters for the diagnosis of disc in mri imaging. MATERIALS AND METHODS: Compare the diagnostic quality of the disc among the T1, PD and T2 images of same patients(12 joints, 223 images) by visual(I-IV grades) and gray level measurement (pre- and infra-discal area) method. RESULTS: PD images showed best results with 43.7% of the images belonging to grade III (good) and with statistically significant higher difference of the gray levels at pre- and infra-discal areas. But there were no grade IV(excellent) images. CONCLUSIONS: PD images are best method among T1, PD and T2 images in diagnosing the disc but since there were no excellent images further imaging parameters should be studied for better images.
