MRI Exam-Specific Parameters: Cardiac Module (Revised 8-10-2023)

Revision History


In addition to the exam-specific instructions in the following tables, review the following information prior to examination selection and submission. Failure to follow the guidance below may result in failure of the submitted examination.

  • Failure to meet anatomic coverage and imaging plane specifications may result in a fail of the submitted examination.



Cardiac MRI with contrast including white blood and delayed myocardial enhancement images

Required Sequences
