Abstract
Methods In six patients with echocardiographically suspected PAPVD, anatomy was evaluated using standard magnetic resonance imaging including angiography. Functional analysis included shunt calculations from standard flowmeasurements. Furthermore, 4D VEC MRI was used for visualization of maldraining pulmonary veins and quantification of flow via the maldraining veins and interatrial communications, if present.
Highlights
In all patients, the diagnosis of partial anomalous pulmonary venous drainage (PAPVD) was confirmed by standard magnetic resonance imaging
Multiple maldraining pulmonary veins were found in three patients
Pulmonary arteries and veins could be clearly distinguished by selective visualization using 4D VEC MRI
Summary
Selective pulmonary venous flow visualization and quantification by flow-sensitive four-dimensional cine magnetic resonance imaging facilitates and improves the accurate diagnosis of partial anomalous pulmonary venous drainage Objectives To assess if flow-sensitive four-dimensional velocity encoded cine magnetic resonance imaging (4D VEC MRI) adds value in diagnosing patients with suspected partial anomalous pulmonary venous drainage (PAPVD). Methods In six patients with echocardiographically suspected PAPVD, anatomy was evaluated using standard magnetic resonance imaging including angiography.
