Abstract: Objective To reconstruct three-dimensional (3D) image of posterior cruciate ligament (PCL) based on MRI and CT image fusion. Methods CT and MRI scans were performed on 12 knees of young men. The Dicom data were extracted and unified. The outline of PCL on MRI imaging was drew and plugged into the CT data. Finally, the visible 3D image of PCL with adjacent bones was reconstructed. The imaging anatomical measurements were examined and compared with those in published literature. Results Two cases were excluded from this study because of data deviations. The 3D visible reconstruction of PCL was proved to be feasible on the other ten cases. Conclusion Three-dimensional visible reconstruction of PCL based on CT and MRI image fusion is feasible, which can provide support for individualized treatment of PCL injuries. Further simplification with increased accuracy may be needed.
