2D or 3D time spatial labeling inversion pulse (time-SLIP) techniques is clinically applied as one of the non-contrast-enhanced pulmonary MR angiography in routine clinical practice. This technique has been suggested as having the capability of separation between pulmonary artery and vein, although the separation of pulmonary vein from artery is more difficult than latter from former. In addition, no one has assessed the influence of slice-selective Tag pulse thickness for time-SLIP technique. The purpose of this study was to prospectively and directly compare the influence of slice-selective Tag thickness for pulmonary MR venography using time-SLIP technique at in vivo study.
