Utility of High-Resolution Sonography for Evaluation of Knee Joint Pathologies As a Screening Tool
Journal of diagnostic medical sonography(2021)
摘要
Objective: Magnetic resonance imaging (MRI) has been established as the gold standard imaging technique for assessing knee joint pathologies. However, high-resolution sonography (HRS) is affordable, easily available, cost-effective, and can be used for knee joint assessment. This study was conducted to assess the diagnostic yield of HRS in the evaluation of knee joint pathologies compared with MRI. Materials and Methods: In the study, 103 patients, with symptomatic knee pain, were included. HRS was performed followed by MRI. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated. Kappa values were calculated to assess the performance of HRS compared with MRI. Results: The most frequent pathologies observed on HRS were knee joint effusion (84%) followed by medial meniscal (43%) and lateral meniscal (26%) tear. Conclusion: HRS demonstrated good diagnostic accuracy in diagnosis of knee joint pathologies as compared with MRI. Therefore, HRS could be utilized as a screening tool for detection of knee joint pathologies.
