Ten-year-old boy with absent pulmonary valve and intact ventricular septum. (a) Contrast-enhanced magnetic resonance angiography axial maximum intensity projection (MIP) reconstruction demonstrated very dilated main pulmonary artery, as expected in this congenital lesion. (b,c) Three-dimensional turbo field echo coronal and axial MinIP reconstruction demonstrated mild to moderate left bronchial compression by the dilated main pulmonary artery.
