From: Paediatric multi-detector row chest CT: what you really need to know
MDCT images of a child with a single pulmonary vein with severe narrowing at the junction where it enters the posterior aspect of the left atrium. This can be seen clearly on both the axial MaxIP image (a) and on the VRT image (b). MDCT is the investigation of choice in patients with venous stenosis due to the superior spatial resolution of CT over MRI. Scanning parameters: 80 kV, 38 eff mAs, 130 ref mAs, 0.66 CTDIvol, 8 DLP
