Figure 1 The magnetic resonance angiography 3D data set is collected as a series of contiguous slabs in either the coronal or sagittal plane. The contrast-enhanced data set shown is a coronal acquisition with the most anterior images to the left of the stack and the posterior structures to the right. Selected images from the data set demonstrate an anomalous right upper pulmonary vein entering the superior vena cava just above the junction with the right atrium (arrow, left), and the right lower lobe pulmonary vein entering the left atrium normally (arrow, right). RLL = right lower lobe; RUL = right upper lobe.
