Core Imaging Protocol

Quantifies: LV & RV Size and Function, Atrial Size, Valvular Regurgitation, Intracardiac Shunt, Tissue Iron

1. 3-plane loc (left image)
2. Axial loc through aortic arch and heart (not shown): multi-slice, single phase, ungated SSFP
3. Use 3-plane loc (left image) to obtain long axis loc (right image): single slice, multiphase
   
4. On 3-plane loc (image 1), Rx parallel to PA to obtain PA loc (image 2): single slice, multiphase
5. On PA loc (image 2), Rx parallel to PA to obtain 2^nd PA loc (image 3): single slice multiphase.
6. On image 3, Rx perpendicular to PA to acquire PA phase contrast (image 4), to quantify Qp
   
7. On 3-plane loc (image 1), Rx parallel to Ao root to obtain Ao root loc (image 2): single slice, multiphase
8. On image 2, Rx parallel to Ao root to obtain 2^nd Ao root loc (image 3): single slice, multiphase
9. On image 3, Rx perpendicular to Ao root to acquire Ao root phase contrast (image 4) to quantify Qs
   
10. On the long axis loc (left image) Rx a stack of short axis images (8 mm thick, 0 gap, right image) perpendicular to the long axis of the LV. The LV long axis is an imaginary line that passes through the center of the mitral valve and the LV apex. Start the first slice in the middle of the left atrium. The last slice should extend past the LV apex.
    
11. Repeat PA Phase contrast. Identical to step 6. (The acquisition is repeated to assess for flow stability.)
12. Repeat Ao Phase contrast. Identical to step 9. (The acquisition is repeated to assess for flow stability.)
13. On a basal short axis image (left image), Rx a 3-chamber long axis view (right image) by bisecting the mitral and aortic valves.
    
14. On a midventricular short axis view (left image), Rx a 2-chamber long axis view (right image) by bisecting the left ventricle while staying parallel to the mid septum
    
15. On a midventricular short axis view (left image), Rx a 4-chamber long axis view (right image) buy bisecting the center of the left ventricle and passing through the point of greatest curvature of the right ventricle.
    
16. Short Axis T2* of the mid-ventricle performed as a single breath-hold.
17. Phantom correction for PA and Aortic phase contrast series.
    • Do not end the study.
    • Place a phantom on the table where patient’s heart was located.
    • Acquire the same phase contrast series as was performed on the patient.
    • Perform a phantom acquisition for each phase contrast Rx that was acquired.
