Abstract:
Objective To specify the diagnostic accuracy of low-field MRI on meniscal tears. Methods Meniscal lesions were examined by using 0.2 T MRI and checked arthroscopically in 171 cases. The results were recorded and compared. Results From the calculation of the arthroscopic findings and the results by MRI, we obtained the diagnostic accuracy rate of 95.91% for both the medial and lateral menisci, sensitivity of 95.60% for the medial menisci and 96.47% for the lateral menisci, and specificity of 96.25% for the medial menisci and 95.35% for the lateral menisci. Conclusions The low-field MRI can bring about high diagnostic accuracy for meniscal tears and has a good price-performance ratio.
