CARDIAC MRI PLANNING 2
Cardiac scan planning-2
Through the arteries and valves
Through the arteries In-Plane
• Aortic arch • Pulmonary artery
• Pulmonary bifurcation
• Left pulmonary artery
• Right pulmonary artery
Aorta arch
• Plan on transverse, use 3pps:
– AAO
– Arch
– DAO
Sagittal oblique
- Aortic valve
- AAO, Arch, DAO
Pulmonary artery (MPA, = RVOT)
• Plan on transverse, through:
– Pulmonary artery
– Straight sagittal
Sagittal
- Right ventricle
- Pulmonary valve
- Pulmonary artery
Pulmonary bifurcation (PB, PT)
• Plan on SAG:
– Straight transverse
Transverse
- Main pulmonary artery
- Left & right PA*
Left pulmonary artery (LPA)
• Plan on transverse PA, through:
– Left pulmonary artery
Sagittal oblique
- Left pulmonary artery
Right pulmonary artery (RPA)
• Plan on transverse PA, through:
– Right pulmonary artery
Coronal oblique
- Right pulmonary artery
Q-flow through arteries
• Perpendicular to vessel:
• Plan on two orthogonal images
Aortic flow
Pulmonary flow
Left pulmonary flow
Right pulmonary flow
Q-flow Aorta Aortic flow
• Plan on LVOT and / or arch:
– Orthogonal to aorta
– 2cm distal to valve leaflets
Q-flow Aorta
Aortic flow:
• AAO (red) ≈ DAO (green) + SVC (blue)*
Q-flow Pulmonary Artery Pulmonary flow
• Plan on RVOT and tra:
– Orthogonal to PA
– 2cm distal to valve leaflets
Q-flow Pulmonary Artery
Pulmonary flow:
• AAO (red) ≈ PA (green)*
Q-flow Left Pulmonary Artery Left pulmonary flow
• Plan on PB and LPA:
– Orthogonal to LPA
– 2 cm distal to bifurcation
Q-flow Right Pulmonary Artery Right pulmonary artery
• Plan on PB and RPA:
– Orthogonal to RPA
– 2 cm distal bifurcation
Q-flow Pulmonary Arteries Pulmonary flow:
• PA (red) ≈ LPA (green) + RPA (blue)
Flow through Valves
• Mitral valve
• Tricuspid valve
Q-flow Mitral valve Mitral valve
• Plan on 4CH and L2CH
– Verify in systole and diastole
Q-flow Tricuspid valve
Tricuspid valve
• Plan on 4CH and R2CH
– Verify in systole and diastole
Q-flow Mitral valve
Mitral valve
– Mitral valve (red)
– Tricuspid valve (green)
Q-flow Tricuspid valve
Tricuspid valve
– Mitral valve (red)
– Tricuspid valve (green)
