Purpose: The anterior cruciate ligament (ACL) is made up of two functional bundles, are called anteromedial bundles (AM) and posterolateral bundles (PL). The study's purpose was to demonstrate the technical importance of oblique coronal MRI to distinguish AM and PL bundles.
Patients and method: The study was conducted in a Baghdad medical city/ institute of radiology. This study included 50 patients (34male &16 female). Patients being referred to evaluation due to knee pain, an accident like knee trauma were included in the study and evaluated by MRI scans performed using MRI scanner (Siemens, 1.5). Results were analyzed by descriptive analysis This study included patients referred to in the MRI examination for 4 months. MRI signs were examined for pain and trauma, the number of slices per ACL procedure, length of additional procedures applied, and test reproducibility.
Results: Magnetic resonance imaging in all cases revealed an intact ACL. The ACL has been evaluated as one bundle in the standard examination(protocol A) in 22 patients (44%), An appearance of double bundles was showed in 22 patients (44%), and not seen in 6 patients (12%).In oblique coronal (protocol B) The ACL has been evaluated as one bundle in 10 patients (20%), A double-bundle appearance has been reported 36 patients (72%) and not seen in 4 patients (8). The gap of MRI detection of the ACL as a single package of additional techniques was not statistically significant (p > 0.37). Coronal-oblique technique offers more MRI slices that view the entire ACL course and a shorter scanning time are required.
Conclusions To conclude, human ACL is made up of two bundles with separate anatomical or functional properties, as shown by anatomical and biomechanical studies; This two-band arrangement can be visualized only in about two-thirds of the patients with oblique coronal MRI examinations.
