MSCT和MRI在膝关节半月板、关节软骨损伤诊断及分期评估中的应用OACSTPCD

Objective:To explore the application value of multi-slice spiral CT(MSCT)and magnetic resonance imaging(MRI)in the diagnosis and staging evaluation of knee meniscus and articular cartilage injury(MACI).Methods:The clinical data of 97 patients with MACI who underwent MSCT and MRI examinations were retrospectively analyzed.Taking arthroscopy results as the golden standard,diagnostic efficiency of MSCT and MRI was analyzed.Results:The diagnostic results of arthroscopy showed that there were 194 meniscus in 97 patients,of which 103 were damaged and 91 were not damaged,97 patients had 582 articular cartilage sur-faces,of which 284 were damaged and 298 were not damaged.MSCT diagnostic results showed that 97 patients had 194 meniscals,106 were damaged,and 88 were not damaged,the MRI diagnosis results showed that in 97 patients had 194 meniscus,109 were damaged,and 85 were not damaged.The accuracy,specificity and sensitivity of MRI in the diagnosis of knee meniscus injury and articular carti-lage injury were higher than those of MSCT(P＜0.05).The diagnostic accuracy rate of knee meniscus injury grading and cartilage in-jury grading by MRI was higher than that by MSCT(P＜0.05).Conclusion:The diagnostic value of MRI is better than that of MSCT in MACI,which can accurately reflect injury severity.
