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	Category A: Pulse Sequence and Image Contrast	Category B: Anatomic Coverage and Imaging Planes	Category C: Spatial Resolution
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 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	Single slice oriented vertically through the middle portion of the left atrium and the middle portion of the left ventricle	Slice thickness ≤ 8.0 mm Pixel area ≤ 4.0 mm² Temporal resolution ≤ 80 msec (without view sharing)
LONG AXIS CINE 4 Chamber	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	Single slice oriented vertically through the middle portion of the left atrium and the middle portion of the left ventricle	Slice thickness ≤ 8.0 mm Pixel area ≤ 4.0 mm² Temporal resolution ≤ 80 msec (without view sharing)
LONG AXIS CINE 3 Chamber (Aortic Outflow Tract)	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 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 mm Pixel area ≤ 4.0 mm² Temporal resolution ≤ 80 msec (without view sharing)
Contrast Enhanced including white blood and delayed myocardial enhancement	Must be gated to the cardiac cycle Must have no significant arrhythmia during the MRI cardiac cycle Inversion prepared gradient echo pulse sequence Must 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 mm Gap ≤ 2.0 mm Pixel area ≤ 5.9 mm2
