The document discusses the anatomy of the knee and basics of MRI examination for knee imaging. It covers MR anatomy of the knee, including signal characteristics of different tissues on T1-weighted, T2-weighted, proton density, and fat-suppressed sequences. Examples given are viewing the cruciate ligaments on T2-weighted sagittal images and collateral ligaments on proton density fat-suppressed coronal images.
