The major challenge affecting prognosis, however, has been on the imaging of partial tears.
Oblique imaging planes, including oblique axial, oblique coronal and oblique sagittal, would improve on the accuracy of diagnosis and detection of any partial tears in the ACL. It would also aid in assessing individual bundle tears. This approach has been noted to be more useful than the standard MRI in cases where ACL tear is anticipated.
The protocol could also benefit from 3D sequences such as the 3D-DESS, known to be isotropic acquisition having the potential of reducing partial volume averaging through acquisition of thin and continuous slices from the joints. Additionally, this could be used to come up with multiplanar reformat images, MPR, which would make the evaluation of ACL possible from any orientation or oblique planes through a single acquisition. This creation of the MPR could be sourced as part of PACS system or through dependent workstations. The MPR images in this context would be useful for acquisition of the oblique planes, including the oblique axial, coronal and sagittal, to better assess the ACL tears.
Finally, the 3D-DEES sequences play a crucial role of enhancing the image’s T2* weighting and also increases synovial fluid and cartilage signal intensities. This 3D-DEES technique is beneficial in the sense that it provides moderate accuracy with regards to early cartilage delineation and high accuracy when detecting advanced cartilage lesions. As such, this sequence can only be employed when dealing with cartilage structures. Replacing this ACL imaging sequence with subtraction-DESS technique would result in its optimisation.
The MRI technology has been beneficial in supporting chronic and acute ligament injuries diagnosis and, even more importantly, in assessing problems that arise after the reconstruction of ligament. Even so, the short T2-relaxation time associated with tendon tissue (4), the standard MRI having echo times, TE,
