PDFAbstract
Objective To investigate the clinical effect of CT and MRI in the diagnosis of femoral head necrosis. Methods Patients with femoral head necrosis in our hospital from Dec. 2016 to Dec. 2017 were selected and given CT and MRI diagnosis, positive rate, stage result and early positive signs detection rate diagnosed by CT and MRI were observed. Results Positive diagnostic rate of MRI (97.67%) was significantly higher than that of CT (84.88%) (P<0.05), the detection rates of BME, single cystic changes, bone trabecula with blurring structure, string sign by CT were 2.33%, 75.58%, 9.30%, 2.33%, which were significantly lower than those of MRI (76.74%, 100.00%, 77.91%, 65.12%) (P<0.05). Conclusion CT and MRI all have better diagnostic effect in the diagnosis of femoral head necrosis, and the positive diagnostic rate of MRI is higher than that of CT, it can also diagnose the correlative symptoms of patients with femoral head necrosis, and the clinical application prospect is wide.
