Abstract

Musculskeletal magnetic resonance imaging (MRI) applications are making the transition rapidly from 1.5 tesla (T) to 3T. The higher signal-to-noise ratio (SNR) that is available with a 3T MRI system allows for greater spatial resolution and provides the potential to improve the diagnostic capability of musculoskeletal MRI. With the use of 3T systems, one can enhance the SNR, spatial resolution, and contrast-to-noise ratio of intrinsic joint structures such as osseous, tendinous, cartilaginous, and ligamentous structures, which makes them more discernable and amenable to proper radiologic assessment. The SNR gain and coil technology advances allow for a smaller voxel-size and parallel imaging, reducing the acquisition time without significant signal loss. Three-dimensional (3D) fast spin echo sequences with isotropic resolution reduce partial volume artifacts through the acquisition of thin continuous sections and enable free 3D-multiplanar-reformatting without loss of image quality. This technique may be a promising method to replace currently used 2D sequences in clinical practice. In addition to current clinical applications, 3T MRI will contribute to the development of new molecular and functional MRI techniques.
