[Abstract] Objective: To discuss the diagnostic value of MRI grayscale flip image in the cortical abnormalities in longbone lesions compared with conventional X-ray and CT images.Materials and Methods: A retrospective study of 100 patients with long bone lesions confirmed by surgical pathology from 2015 to 2019, there were 30 cases of bone tumor, 60 cases of trauma and 10 cases of bone infection. All patients were examined by DR, CT and MRI. Select MRI-T1WI image and right-click the mouse and click the corresponding tool options to obtain the grayscale flipped image instantly. The detection of cortical bone abnormalities (interruption, thickening, thinning) was statistically analyzed, compared with X-ray and CT, statistical analysis was performed using χ2 test analysis.Results: MRI gray scale flip image detected 79 cases of cortical abnormalities, with a detection rate of 79%, and 84 cases of X-ray detection, with a detection rate of 84%, CT images detected 100 cases of cortical abnormalities, with a detection rate of 100%. There was no statistical difference between MRI grayscale flip image and X-ray image in displaying of cortical abnormalities. MRI flip images and CT images have statistically significant differences in the detection of cortical abnormalities.Conclusions: MRI grayscale flip images are useful for assessing bone cortical abnormalities in long bone lesions, in the absence or inability to obtain plain X-ray or CT images (e.g., pregnant women), MRI grayscale flip images can be used to observe the cortical bone.
