Abstract

Objective: To investigate the imaging method of posterior cruciate ligament(PCL) and its normal appearances in MRI. Methods: The T2-weighted, 3-dimensional multi echo data imaging combination(3D-MEDIC) sequence were applied on 40 cases of normal volunteers. The anatomy of the PCL was displayed on multiple planar reconstruction(MPR) imaging. Result: The reconstructed PCL had good morphology and well-defined boundary, providing precise anatomic data. The width and thickness in the middle part of the PCL were (1.13±0.17)cm and (0.49±0.10)cm, respectively. The length and deveation angle of anterior lateral bundle and posterior medial bundle of the PCL were (3.78±0.36)cm and (2.58±0.35)cm, and 24.0°±4.6° and 19.1°±5.5°, respectively. The elevation angle of PCL was 40.1°±4.43°. Conclusion: Using MPR 3D high resolution MRI can contribute to display the PCL.
