“…Our study showed that there is a higher interobserver agreement in diagnosis of complete and partial ACL tears using approaches B, C, and D in comparison to approach A, being highest with approaches C and D. This is in agreement with Kosaka et al, which showed higher diagnostic performance and interobserver agreement when using additional oblique coronal images [20]. The main reason for this is that oblique coronal images clearly delineate the course and femoral attachment of the ACL.…”

Background: The aim of the study was to evaluate the diagnostic efficacy of utilization of oblique sagittal and oblique coronal MRI techniques separately and concurrently in improving the diagnosis of anterior cruciate ligament (ACL) complete and partial tears. Between December 2017 and November 2018, 71 patients, with suspected ACL injury, were examined by MRI using four diagnostic approaches: standard routine images only (approach A), standard and oblique coronal images (approach B), standard and oblique sagittal images (approach C), and standard images with both oblique coronal and sagittal images (approach D). Two experienced musculoskeletal radiologists evaluated the MRI images separately and in a random order using the four methods, and findings were compared with arthroscopy results as a gold standard. Results: The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for approach A in diagnosis of partial ACL tear was significantly lower than that for approaches B, C, and D (p value < 0.05). The PPV and NPV for approaches B (82% and 85%) and C (83% and 87%) in diagnosis of partial ACL tear which were significantly lower than that for approach D (94% and 95%). The four approaches revealed no significant difference in diagnosis of complete ACL tear (p value > 0.05). Approach D demonstrated highest interobserver agreement (94% in complete and 88% in partial ACL tears) in comparison to B (79% in complete and 66% in partial) and C (85% in complete and 71% in partial) when combining oblique sagittal and oblique coronal images in identifying both complete and partial ACL tears Conclusion: The addition of oblique sagittal and coronal images improved diagnostic accuracy of detection of complete and partial ACL tears. The concurrent use of sagittal and coronal oblique images enhanced the diagnostic efficacy of diagnosis of partial ACL tears only.

“…Finally, they conclude that the use of oblique MRI improved the accuracy of diagnosis of ACL [11]. According to previous studies, orthogonal MRI protocol and oblique-sagittal MRI were better than other oblique images; however, in this study, we found that using orthogonal sagittal and oblique coronal images show much better results than oblique sagittal images.…”

“…Tackling this issue, Kosaka et al demonstrated that a new method was not needed, as MRI accuracy can be increased by using a different view of knee lesions such as ACL injury. They found that the additional use of oblique MRI improved the accuracy of diagnosis of ACL tear [11]. Moreover, Nenezic et al showed that additional use of sagittal-oblique MRI has high accuracy for the evaluation of a complete rupture of the ACL.…”

Introduction Tears of the anterior cruciate ligament (ACL) are common among young athletes and diagnosis may be difficult especially in the young population. Therefore, finding a new method to increase the correct diagnosis is necessary. Materials and Methods This double-blind prospective observational study was conducted on 51 patients with suspected ACL rupture. In this study, in addition to the standard protocols, the oblique-sagittal and oblique-coronal MRI were assessed and used in three different methods, including A method (orthogonal MRI protocol), B method (orthogonal MRI protocol and oblique-sagittal MRI), and C method (orthogonal MRI protocol and oblique-coronal MRI). Results In detecting both complete and partial rupture of ACL, B method had highest diagnostic accuracy (kappa = 0.338, P=0.001), and after that, C method had acceptable accuracy (kappa = 0.292, P=0.011). In addition, in detecting a partial rupture of ACL, B method (kappa = 0.5, P<0.001), and C method had acceptable accuracy (kappa = 0.361, P=0.006). Meanwhile, in detecting a complete rupture of ACL, B method had the highest diagnostic accuracy (kappa = 0.898, P<0.001), and subsequently A method had significant accuracy (kappa = 0.812, P<0.001). Conclusions Our results showed that the evaluation of ACL rupture by oblique-sagittal MRI in addition to orthogonal MRI protocol is accurate and with high sensitivity and specificity values. It allows to find abnormal images immediately with higher accuracy in the emergency department and more critically ill patients may benefit from the advantages of this imaging protocol.

“…First, ROI was evaluated using only sagittal MRI images rather than oblique coronal or oblique sagittal images, which have been reported to distinguish anteromedial and posterolateral bundles with greater accuracy. 32 In addition, it is relatively difficult to diagnose the small disruption of a proximally torn ACL that has adhered to the PCL or maintained gross alignment using a sagittal sequence. In such cases, axial or coronal plane images may allow a more accurate diagnosis.…”
