Course Description

MRI Online’s most recent addition to the course catalogue is MRI Mastery Series: Intradural Extramedullary Spinal Lesions (IDEM). In Dr. Yousem’s second part of the spinal lesions series, he dives into one of his favorite topics because, in general, it deals with benign entities.

Some of the topics included in this week’s course include:

  • Schwannomas
  • Neurofibromatosis Type 1 & 2
  • Meningiomas
  • Hemangioblastomas
  • Lipoma
  • Dural Ectasia
  • And many more…
