title: MR imaging of the foot: utility of complex oblique imaging planes.
abstract: Successful MR imaging of the foot presents special challenges to the radiologist. Accurate and confident diagnosis presupposes the ability to produce high-resolution images of obliquely oriented, relatively small structures. Orienting the foot within an appropriate local coil to bring such structures into an orthogonal imaging plane, or even into a conventional oblique plane, may be impossible or intolerably uncomfortable for the patient. The frequent result is motion artifacts, which are accentuated when using a small field of view. However, when patients are comfortably positioned, the anatomy of interest often lies in a plane that is not orthogonal to any of the conventional imaging planes. Fortunately, commercially available MR imaging equipment can produce images in complex oblique planes with relative ease. In this pictorial essay, we discuss the technical considerations for expedient diagnostic MR imaging of the complex anatomy of the foot and illustrate our experiences with this technique.
