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.

  • The axial black blood sequence may be from a different patient from the other sequences.

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



Delayed Enhanced Cine with Black Blood

Required Sequences

Category A: 

Pulse Sequence and Image Contrast

Category B: 

Anatomic Coverage and Imaging Planes

Category C: 

Spatial Resolution

BLACK BLOOD Axial or Oblique Axial

  • Must be in the axial or oblique axial plane

  • Must have good myocardium discrimination (including good blood suppression)

  • TE can be optimized for your system, but should be proton density/ T1 weighted (less than approximately 45 msec)

  • This sequence may be from a different patient from the other sequences
