usculoskeletal pathology is common to any radiology practice and includes trauma, degenerative processes, nerve disorders, and masses, to name a few types. Although radiographic evaluation is the initial imaging method to assess musculoskeletal pathology, the next step in imaging is often magnetic resonance imaging (MRI). The benefits of MRI are numerous, which include evaluation of soft tissues, cartilage, ligaments, and intraosseous structures. With the introduction of intra-articular contrast, detailed depiction of subtle intra-articular anatomy and pathology is possible. Indeed, MRI is considered the standard of care for imaging assessment of many musculoskeletal pathologies. Familiarity with such pathologies is important to provide an accurate imaging diagnosis. It is an honor to serve as Guest Editor for this issue of Seminars in Roentgenology, which will focus on musculoskeletal MRI. I am fortunate that the leading experts in musculoskeletal MRI have agreed to contribute. In this issue, each article will focus on MRI of a lower-extremity peripheral joint. In an additional article, soft-tissue masses are reviewed. The first article is authored by Drs. Brian, Bernard, and Flemming and focuses on an important hip topic, femoroacetabular impingement. They review the general principles behind femoroacetabular impingement and provide a comprehensive review of MRI findings. Correlation is also made with radiographic findings.

The article on the knee by Drs. Shapiro, Staroswiecki, and Gold from Stanford University provides a timely review of how to optimize 3 Tesla imaging of the knee. This article also includes specific parameters for a 3 Tesla MRI protocol. Future directions in cartilage imaging are also reviewed. In the next article Drs. Petersen, Fitzgerald, and Schreibman review ankle MRI, with a focus on muscle and tendon pathology. This article provides a comprehensive review of tendon pathology and includes a discussion of normal variations. MRI has an important role in characterizing soft-tissue masses. In this final article, Drs. Walker, Song, and Murphey review benign and malignant soft-tissue masses. Discussion also includes general principles of MRI as it pertains to imaging of masses, its role in tumor delineation, and important aspects of MRI reporting. This issue of the Seminars in Roentgenology provides a review of musculoskeletal MRI, focusing on specific topics related to peripheral joints and soft tissues. I hope that you find the material by these leading authors enjoyable and educational. Jon A. Jacobson, MD Guest Editor
