title: Variants and pitfalls in MR imaging of the spine.
abstract: MR imaging is a valuable tool in investigating the spine and is the diagnostic modality of choice in an increasing number of conditions. Advent of newer 3-T machines has taken MR imaging to a different level, with increased image resolution. Higher field strength magnets have also resulted in an increased number of artifacts. A sound knowledge of human anatomy and awareness of the common anatomical variants is an essential prerequisite in MR imaging of the spine because a variety of normal variants and benign conditions may potentially be confused with serious pathologies. This can significantly affect patient management, and it is essential to avoid such misdiagnoses. Identifying and eliminating the common artifacts on MR imaging can result in a significantly improved image quality. Awareness and knowledge of the common variants, common artifacts, and important distinguishing features among similar-appearing pathologies are important in avoiding the various potential pitfalls in spine imaging.
