During the past decade, several novel procedures have been introduced as a new version of non-CE-MRA angiography using 2D or 3D fresh blood imaging (FBI) obtained with an ECG-gated 3D half-Fourier fast spin-echo sequence, and 2D or 3D time spatial labeling inversion pulse (time-SLIP) techniques. However, to the best of our knowledge, no direct comparison has been made of assessment of pulmonary vasculature in candidates for thoracic surgery by non-CE-MRA, 4D CE-MRA at 3T, and thin-section CE-MDCT. The purpose of this study was to compare assessment of pulmonary vasculature in NSCLC patients before surgical treatment among three methods.
