Clinical Efficacy and Accuracy Analysis of CT and MRI in Diagnosing Femoral Head Necrosis
Objective To analyze the clinical efficacy and accuracy analysis of CT and MRI in diagnosing femoral head necrosis. Methods The clinical data of 50 patients with femoral head necrosis who were treated in Jinan Seventh People's Hospital from January to December 2023 were retrospectively analyzed. All patients were examined by CT and then by MRI. The diagnostic accuracy,misdiagnosis rate,image quality,and effective radiation dose of CT and MRI scans were compared. Results The diagnostic accuracy of MRI examination (98.00％) was higher than that of CT examination (82.00％),and the misdiagnosis and missed diagnosis rate (2.00％) was lower than that of CT examination (18.00％),the difference was statistically significant (P<0.05). The overall excellent rate of image quality in MRI examination (96.00％) was higher than that in CT examination (80.00％),and the difference was statistically significant (P<0.05). The effective radiation dose for MRI examination was 0 mSv,which was lower than (6.18±0.36) mSv for CT examination,and the difference was statistically significant (P<0.05). Conclusion MRI examination has higher image quality and diagnostic accuracy than CT examination in the diagnosis of femoral head necrosis,and its safety is also relatively high,therefore its clinical application value is higher.
