Arthroscopic And Low-Field MRI (0.25T) Evaluation Of Meniscus And Ligaments Of Painful Knee.

Objective: Magnetic resonance imaging (MRI) is an accurate,non-invasive, cost-effective technique for examination of the soft tissue andosseous structures of the knee. The purpose of this study was to evaluate theaccuracy of low-field MRI by comparing the results with subsequentarthroscopy.Materials and Methods: MR imaging study of146patients was doneusing0.25T ESTOATE G-SCAN and the sequence used were SE, FSE andGRE in all the three planes. The comparison was based on five parameters:accuracy, sensitivity, specificity, positive predictive value, and negativepredictive value. Result: Our study showed high accuracy (98.08%) andnegative predictive value (98.62%) for MRI in comparison with arthroscopy.Conclusion: Low-field MRI alleviates the need of arthroscopy for detectionof meniscus tears and ligament tears.
