摘要:

This article discusses the normal magnetic resonance (MR) appearance, functional anatomy, and biomechanics of the knee joint. Technical considerations of MR imaging of the knee are covered first: coil selection, positioning, and pulse sequences. Useful sequences for both routine examinations and specific clinical situations are suggested. This is followed by a discussion of the biomechanics and functional anatomy of the knee. The typical MR appearance of various key structures in the knee is discussed. The final section of the article is an atlas of normal MR anatomy of the knee, covering the sagittal, coronal, and axial planes.

摘要:

Magnetic resonance imaging (MRI) is the technique of choice to depict normal anatomy and to image internal derangements of the knee. The overall accuracy of this method can reach approximately 94%. MRI can effectively replace diagnostic arthroscopy for evaluation of meniscal and ligamentous tears.

摘要:

A variety of bone and cartilage abnormalities can be demonstrated on magnetic resonance imaging (MRI), which can play an important role in the diagnosis and management of these abnormalities. Ischemic bone lesions, including medullary bone infarction, primary osteonecrosis, and the osteochondroses, can be precisely evaluated as to their anatomic locations and relationship to overlying cartilage. Osteochondritis dissecans may also be diagnosed and staged. Presence of subchondral fractures and bone contusions, which are frequently associated with ligament and meniscal injuries, can also be diagnosed and followed; these conditions may play a role in the evolution of osteoarthritis. The changes of osteoarthritis, including cartilage abnormalities, cyst formation, and loose bodies, can be evaluated; this evaluation may be important in the assessment of therapies. Stress fractures often have characteristic appearances, and MR may be used in making this diagnosis, especially when symptoms and other imaging are unclear. Diffuse marrow disorders including hemoglobinopathies and neoplasia are also well demonstrated.

摘要:

Magnetic resonance imaging (MRI) of the knee is the most frequently performed joint MRI examination. The use of MRI has revolutionized assessment of both intra-articular and periarticular musculoskeletal masses about the knee and has largely supplanted other radiologic methods of evaluation. The purpose of this article is to review the MRI appearance of the numerous types of soft-tissue and cystic masses that arise about the knee.
