1 Φεβ 2010 · Radiography, CT, and MRI will show a malpositioned tibial tunnel (Fig. 7A, 7B). MRI may show increased signal in the graft on T1- and T2-weighted sequences in the setting of notch impingement [ 13 ] ( Fig. 8 ).
Eighty-two consecutive knees with an MRI report diagnosis of ACL injury (partial tear, sprain, or complete tear) or tibial spine avulsion fracture imaged over 4 years were retrospectively reviewed. Patients were grouped by degree of skeletal maturity as determined from the MR images.
4 Οκτ 2024 · This article outlines an effective MRI imaging technique that improves the diagnostic accuracy of ACL injuries of the knee, covering the appropriate pulse sequences and optimal imaging planes. Furthermore, the article provides a comprehensive review of the appearance of complete and partial ACL tears on MRI in the acute and chronic phases.
Injury of the ACL can lead to substantial disability; an accurate diagnosis of ACL injury is vital in both short-term and long-term patient care. Magnetic resonance (MR) imaging has emerged as the study of choice to evaluate the status of the ACL and other associated structures in the knee.
18 Σεπ 2017 · MR imaging features of ACL injury. MR imaging is highly accurate in evaluation of ACL tears with an overall sensitivity of 83% to 95% and specificity of 95% to 100%. ACL injuries may involve the substance of the ACL, an avulsion of its tibial attachment ( Fig. 5 ), or a peel off lesion of its femoral attachment.
