Abstract:
In pulmonary vein isolation as a treatment for atrial fibrillation the proximal part of the pulmonary veins is catheterized. A protocol for preinterventional assessment of pulmonary vein anatomy was developed, based on contrast-enhanced magnetic resonance angiography (MRA) in combination with three-dimensional visualization to tailor periprocedural angiography. The results allow for assessment of the number, morphology, and location of the ostia of the pulmonary veins, as well as complicating anatomical variations, such as common trunks and aberrant courses.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
