Modified on: Fri, 13 Dec, 2019 at 11:14 AM
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 gated to the cardiac cycleMust have no significant arrhythmia during the MRI cardiac cycleMust be T1 (1 R-R/short TE) or proton density weighted (2 R-R/short TE)Must be in the axial or oblique axial planeMust 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 mmGap ≤ 4.0 mmPixel area ≤ 4.0 mm2
|
SHORT AXIS CINE | Must be gated to the cardiac cycleMust have no significant arrhythmia during the MRI cardiac cycleReal time cine images are not acceptableMust show entire systolic cycleMust have good myocardium discriminationMust image end systole and end diastoleSteady 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 mmPixel area ≤ 4.0 mm2Temporal resolution ≤ 80 msec (without view sharing)
|
LONG AXIS CINE 2 Chamber | Must be gated to the cardiac cycleMust have no significant arrhythmia during the MRI cardiac cycleReal time cine images are not acceptableMust show entire systolic cycleMust have good myocardium discriminationMust image end systole and end diastoleSteady State free precession technique is preferred, but fast gradient echo is allowed
| Single slice oriented vertically through the middle portion of the left atrium and the middle portion of the left ventricle
| Slice thickness ≤ 8.0 mmPixel area ≤ 4.0 mm2Temporal resolution ≤ 80 msec (without view sharing)
|
LONG AXIS CINE 4 Chamber | Must be gated to the cardiac cycleMust have no significant arrhythmia during the MRI cardiac cycleReal time cine images are not acceptableMust show entire systolic cycleMust have good myocardium discriminationMust image end systole and end diastoleSteady State free precession technique is preferred, but fast gradient echo is allowed
| Single slice oriented vertically through the middle portion of the left atrium and the middle portion of the left ventricle
| Slice thickness ≤ 8.0 mmPixel area ≤ 4.0 mm2Temporal resolution ≤ 80 msec (without view sharing)
|
LONG AXIS CINE 3 Chamber (Aortic Outflow Tract) | Must be gated to the cardiac cycleMust have no significant arrhythmia during the MRI cardiac cycleReal time cine images are not acceptableMust show entire systolic cycleMust have good myocardium discriminationMust image end systole and end diastoleSteady State free precession technique is preferred, but fast gradient echo is allowedMust include left atrium, left ventricle, mitral and aortic valves and aortic root in the same imaging plane
| Single slice oriented vertically through the middle portion of the left atrium and the middle portion of the left ventricle
| Slice thickness ≤ 8.0 mmPixel area ≤ 4.0 mm2Temporal resolution ≤ 80 msec (without view sharing)
|
DELAYED GADOLINIUM ENHANCED Short axis | Must be gated to the cardiac cycleMust have no significant arrhythmia during the MRI cardiac cycleInversion prepared gradient echo pulse sequenceMust choose TI so that there is good suppression of normal myocardium
| Must cover entire left ventricle from base to apex in the short axis
| Slice thickness ≤ 10.0 mmGap ≤ 2.0 mmPixel area ≤ 5.9 mm2
