Abstract
t l T g p t i t q Magnetic resonance imaging (MRI), with its excellent tissue contrast, high spatial resolution, and multiplanar apability, has become the modality of choice in assessing oint pain. Currently, the majority of magnetic resonance rotocols used by institutions rely on 2-dimensional (2D) ultislice acquisitions acquired in various planes. These seuences demonstrate excellent soft-tissue contrast and high n-plane spatial resolution as well as high diagnostic accuacy, particularly when evaluating for internal derangeent.1-3 However, relatively thick slices, and interslice gaps, lead to volume averaging, which can obscure pathology, particularly when evaluating the articular cartilage. Volumetric 3-dimensional (3D) imaging provides thinner slices, higher in-plane spatial resolution, and reduced partial volume averaging. An additional advantage of 3D imaging is the ability to create multiplanar reformations in any plane after a single acquisition. The article will discuss various 3D techniques currently being used to evaluate the musculoskeletal structures.
