BLACK BLOOD Axial or Oblique Axial 

• Must be gated to the cardiac cycleMust have no significant arrhythmia during the MRI cardiac cycle

• Must be T1 (1 R-R/short TE) or proton density weighted (2 R-R/short TE)

• 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

• Must cover from aortic root to diaphragm (axial)

• Slice thickness ≤ 8.0 mm

• Gap ≤ 4.0 mm

• Pixel area ≤ 4.0 mm2

SHORT AXIS CINE

• Must be gated to the cardiac cycle

• Must have no significant arrhythmia during the MRI cardiac cycle

• Real time cine images are not acceptable

• Must show entire systolic cycle

• Must have good myocardium discrimination

• Must image end systole and end diastole

• Steady State free precession technique is preferred, but fast gradient echo is allowed

• Must cover entire left ventricle from base to apex

• Slice thickness ≤ 10.0 mm

• Pixel area ≤ 4.0 mm²

• Temporal resolution ≤ 80 msec (without view sharing)

LONG AXIS CINE 2 Chamber

• Must be gated to the cardiac cycle
