Zero Echo Time (ZTE) MR imaging provides “CT-like” contrast for cortical bone of the knee. We compared sagittal images of CT and ZTE of 15 patients, and demonstrated inter-modality agreement between morphology of the cortical bone of the tibia from CT and ZTE images. Metallic screws were blurred on ZTE in patients who underwent Anterior cruciate ligament (ACL) reconstruction. ZTE may be used clinically instead of CT in some cases who can undergo ACL reconstruction.
