As the interaction between radiologists and neurosurgeons has evolved with the avalanche of outside imaging and anywhere access to PACS, it is more important than ever that every neurosurgeon has sufficient knowledge of common imaging pitfalls and artifacts so that they are not mistaken for pathology. During this seminar, there is four presentations reviewing artifacts and pitfalls on CNS MR, CT, MRA and CTA as well as advanced imaging techniques such as perfusion. Advanced imaging artifacts are reviewed as well, such as errors in MR perfusion calculations due to susceptibility artifacts, elevated choline levels on MR spectroscopy in non-neoplastic disease and benign disease that may have elevated rCBV on perfusion imaging. Audience response cases are incorporated into each talk for the 2020 program.

Learning Objectives: After completing this educational activity, participants should be able to:

  • Recognize common artifacts and pitfalls of CT imaging: motion, photon starvation, beam hardening, and volume averaging with emphasis on rules that allow the viewer to differentiate these from real pathology.
  • Recognize common artifacts and pitfalls of MR imaging: ghosting, wrap around, chemical shift, flow, as well as MRA artifacts related to direction of flow and saturation.
  • Recognize pitfalls and limitations of CTA.
  • Identify basics of MR perfusion imaging and how errors that occur in both data acquisition and processing can lead to misdiagnosis.
