Visualization of the left pulmonary artery stenosis (pointed inside the circle) using the three different imaging modalities. A. Catheterization table shown in the left. Cranial (α) and left-rght (β) angulations are used to acquire the RAO projection shown in the right (XRA). B. The MRI data-set volume is reformatted using the same cranial (α) and left-rghti (β) angulations to acquire the RAO plane, shown in the right (CE-MRIXRA). C. The MRI data-set is reformatted using different cranial (δ) and left-reight (ε) angulations to acquire a cross-sectional area of the vessel, shown in the right (CE-MRIcross).
