Right coronary artery

About this task

Use these steps to acquire right coronary artery images.

Step-by-step instructions

  1. Prescribe and acquire a sagittal localizer with an ungated 2D FIESTA sequence or 2D FIESTA with Real Time Imaging Option.
  2. On a sagittal localizer, prescribe and acquire an ungated 2D FIESTA series of axial scans covering the root of the vessels to the apex.

  3. Prescribe an oblique coronal through the right ventricle.
    1. Identify the atrio-ventricular groove of the RCA.
    2. Prescribe a single oblique coronal slice through the right ventricle, perpendicular to the A-V groove using a gated 2D FIESTA or a 2D FastCine with FatSAT sequence.
    3. Click Save and Scan.

  4. Prescribe the RCA images using one of the following sequences:
    • 2D FastCine Fat SAT (bright blood)
    • 2D SPIRAL FSPGR (bright blood)
    • 3D FIESTA Fat SAT (bright blood), T2 Prep (3D Heart option for 1.5T systems)
    • Adjust the trigger delay on the Cardiac tab to capture the diastolic phase (typically 350 to 450 msec.).
    • Use FSE Double IR (dark blood) for congenital abnormality cases.
