Abstract Objective: To supply reliable imaging data for clinical diagnosis and treatment, we combine the anatomy peculiarities of cruciate ligament of knee joint with the manifestation of MR imaging in order to find best protocol for MR imaging and observe the MRI manifestation of cruciate ligament. Methods: Thirty cases of adult knee joints with injury of cruciate ligament were scanned by MRI with spin echo of sagittal surface and inclined sagittal surface knee joint in extending position, slightly bending position and bending position. The manifestation of cruciate ligament from different position and different angle in sagittal view were observed on work station. Results: ①The display of injured anterior cruciate ligament(ACL): the complete display rate of ACL in vertical and inclined sagittal surface in extending position is 46.7% and 53.3% respectively. The complete display rate of ACL in inclined sagittal view of vertical and inclined sagittal view in slightly bending position is 80.0% and 80.0% respectively. Complete display of ACL in vertical and sagittal view of bending position is 90.0% and 90.0% respectively. ②The manifestation of MRI of cruciate ligament. It’s difficult to identify the slight high signal appeared in the partial cruciate ligament tears. In complete ligament tears it appears a break or defect in the ligament or a ball-like high signal at the attachment of the ligament. Conclusion: MRI in sagittal view of bending position was the best plane for showing ACL tear. It has a leading significance for the diagnosis and treatment in cruciate ligament injury.
