Abstract
Objective To improve the accuracy of MRI diagnosis by comparative analysis of the MRI symptom and arthroscope view of meniscal tear. Methods 76 cases of meniscus in our hospital were selected to analyze their MRI symptoms. All cases were examined by arthroscopy in 2 weeks. The arthroscopic findings were then compared with the MRI diagnoses. Results This study showed that 30 cases are Grade HI injuries by MRI; 28 cases were Grade III (i.e. tear) by arthroscopy. The diagnoses of 22 cases by MRI were consistent with those by arthroscopy. 8 cases, being suspicious tears by MRI diagnosis, were negative by arthroscopy. 6 cases being negative by MRI diagnosis, were tear by arthroscopic analysis. Our results showed that the sensitivity and specificity of MRI diagnosis of meniscal tears were 79% and 93%, respectively. Conclusions An effective strategy to improve the diagnostic accuracy of MRI of meniscal tears through MRI diagnosis: MRI diagnosis should be combined with the clinical symptoms, diagnosis of the of the high signal intensity within the meniscus should be accurate to prevent the surrounding ligaments be mistaken for a torn meniscus signal. Linear high signal layers should be accurately identified. The analysis of meniscus deformation and diffuse high-signal analysis should be combined with the concurring signs. Bucket-handle tear of the signs should be clearly observed.关键词
