Diagnostic Accuracy of Magnetic Resonance Imaging in Anterior Cruciate Ligament Injuries of Knee Joint, in Comparison With Arthroscopy
Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 1
Abstract
Aim: To determine the accuracy of Magnetic Resonance Imaging in detecting Anterior cruciate ligament injuries of knee, while taking arthroscopy as gold standard. Methodology: 70 patients referred to the Department of Radiodiagnosis for Magnetic Resonance imaging with clinical suspicion of having ligamentous injuries of knee were included in the study after applying nclusion and exclusion criteria.MR imaging of the knee was done with T2WI,T2WI and PD sequences in axial, sagittal and coronal planes. Arthroscopic correlation and statistical analysis was done for these patients Results: Magnetic resonance imaging was found to be accurate and non invasive modality for the assessment of ligamentous injuries. The sensitivity, specificity, accuracy, positive predictive value, negative predictive value, positive and negative likelihood ratios of ACL tear were 95%, 83%,93%, 96%, 77%, 5.6 and 0.06, Thus, MRI is an appropriate screening tool for therapeutic arthroscopy, and also the test performance is towards diagnostic side than screening, so that it makes diagnostic arthroscopy unnecessary in most of the patients
