Abstract
Objective:
Magnetic resonance imaging (MRI) is an accurate, non-invasive, cost-effective technique for examination of the soft tissue and osseous structures of the knee. The purpose of this study was to evaluate the accuracy of low-field MRI by comparing the results with subsequent arthroscopy.
Materials and Methods:
MR imaging study of 146 patients was done using 0.25 T ESTOATE G-SCAN and the sequence used were SE, FSE and GRE in all the three planes. The comparison was based on five parameters: accuracy, sensitivity, specificity, positive predictive value, and negative predictive value.
Result:
Our study showed high accuracy (98.08%) and negative predictive value (98.62%) for MRI in comparison with arthroscopy.
Conclusion:
Low-field MRI alleviates the need of arthroscopy for detection of meniscus tears and ligament tears.
