Accuracy of low-field MRI on meniscal tears

Abstract

ABSTRACT. This study aimed to verify the accuracy of lowfield-intensity magnetic resonance imaging (MRI) in diagnosing meniscus tears. A total of 171 patients were examined through low-field-intensity MRI to detect meniscus injuries. These patients were then diagnosed through arthroscopy. Examination results were recorded and compared. The accuracy of the diagnosis for internal and external meniscus tears through low-field-intensity MRI was 95.91% and 95.91%, respectively, the sensitivities were 95.60% and 96.47%, respectively, and the specificities were 96.25% and 95.35%, respectively. Low-field-intensity MRI is an accurate and cost-effective method for diagnosing meniscus tears.

A Current Review of the Meniscus Imaging: Proposition of a Useful Tool for Its Radiologic Analysis

“…Diagnostic sensitivity for medial meniscal lesions is between 86% and 96% with a specificity of 84% to 94%. The diagnostic sensitivity for the lateral meniscus is between 68% and 86%, with a specificity between 92 and 98% [ 16 , 21 – 30 ]. The differences in sensitivity and specificity could be due to the sequences used, intraobserver variations or the size of the study population.…”

A new method to diagnose discoid lateral menisci on radiographs

“…Last but not least, MRI has contraindications for patients with magnetic metallic implants or claustrophobia. These limitations prompt the investigating of the feasibility of diagnosing discoid lateral meniscus using radiography, which has advantages in popularity, easy access and no contraindications [6, 16].…”

Magnetic resonance tomography of the knee joint

“…This is supported by newer primary studies not included in this review, e.g. [23]. The accurate diagnosis and characterisation of cartilage lesions, however, are difficult, if not impossible, in the setting of low-field strength imaging.…”
