Educational Objectives

At the completion of this program, participants will:

  • Understand the creation of the MRI signal, from precession to detection by the RF coil.
  • Explain basic tissue characteristics (TI, T2, PD, and T2*) and identify images by these characteristics.
  • Describe the various instrumentation systems used in MRI and their purpose, including gradients, radiofrequency, magnet and coils.

How it Works:

  • Your On Demand CE activity that you purchased will be located in your “My Account” section once you log into the MTMI Website.
  • You have three attempts to pass each quiz.
  • You must earn a score of 75 % or higher.
  • Credit is recorded the day you submit and pass the quiz and is determined using Central time.
  • You have 30 days to complete and pass the quiz.
  • Once passed, access your MTMI “My Account” to print your “Certificate of Completion.”
