PDFAbstract
Objective To investigate the positive rate and specificity of MSCT and MRI in diagnosis of subtle and occult fractures. Methods 180 cases of subtle and occult fracture patients were selected from our hospital, and the diagnosis was made by MRI and MSCT respectively. The results of the two detection methods were compared. Results The detection rate of MSCT and occult fracture was 85.56%, and the detection rate of MRI was 96.67%, the difference was statistically significant (P=0.000).The specificity of MSCT in the detection of failure fracture, fatigue fracture and occult fracture is higher than MRI,but the difference was not statistically significant (P＞0.05),which was statistically significant (P=0.049) in specificity of the detection of the hidden fractures in the stock of MRI (74.29%) and MSCT (94.29%). Conclusion Both MSCT and MRI have certain application value in the diagnosis of subtle and occult fractures, but the detection rate and specificity of MRI can provide more reliable data for clinical evaluation and treatment.
