Plane Selection in CMR In Memory of Bill Woodward Craig Broberg, MD Oregon Health and Science University
2
Start with Axial Spin Echo Stack Line up for Vertical Long Axis (VLA) LA RA LV RV mitral valve apex
3
Then Line up for short axis scout (SCOUT basal and mid) Result: VLA LA LV mitral valve Note: Can be done as non-gated single-phase image (non-cine).
4
Result: Scout Basal Mid RV Aorta LV/mitral valve RV LV RV
5
Scout (basal)VLA Line up for left ventricular outflow tract (LVOT) Aorta LV RV LV LA Through maximum diameter of LV Through apex
6
LVOT Line up for Aortic Valve (AoV) LA Aorta LV RV Note: plane should be perpendicular to LVOT Align through center of Aortic valve
7
AoV
8
Line up for Four Chamber (4Ch) VLASCOUT (mid) LA LV RV Center of mitral valve Max diameter of RV and LV
9
4 Ch LA RA LV RV
10
Make sure both images are set at END Diastole Line up for Short Axis Stack (SA) VLA 4 Ch LA RA LV RV LA LV First slice should align with valves
11
SA (base to apex) basal mid LV RV apical
12
Axial Spin Echo Stack Line up for Right Ventricular Outflow Tract (RVOT) LPA RPA MPA View planes above and below
13
RVOT Line up for Pulmonic Valve (PV) MPA RV Pulmonic valve
14
PV Pulmonic valve MPA RV
15
Line up for Right Pulmonary Artery (RPA) Axial Spin Echo Stack RPA MPAAorta
16
RPA LA RPA LV MPA
17
Axial Spin Echo Stack Line up for Left Pulmonary Artery (LPA) LPA MPA Aorta
18
LPA MPA LPA
19
RPALPA Line up for Pulmonary Arteries (PAs) MPA RPA LPA MPA Try to align through center of both RPA and LPA, though may not be possible
20
PAs RPA Aorta LPA MPA
21
4ChSA (basal) Line up for RV inflow-outflow (RV IN OUT) RVOT RV RV/Tricuspid RA Pulmonic valve (“out”) Tricuspid valve (“in”) RV apex Try to avoid LVOT/AoV here
22
RV IN OUT RA RV MPA Tricuspid valve Pulmonic valve
23
Aorta
24
LVOT AOV Line up for Aortic velocity map (AO FLOW) RA RV Aorta LV Sinotubular junction
25
AO FLOW
26
RVOTMPA Line up for pulmonary artery velocity map (PA FLOW) RV MPARV MPA Stay above pulmonic valve
27
