Non-contrast enhanced pulmonary MRA has been increasingly used for the diagnosis of abnormality of vessels such as pulmonary arteriovenous malformation (PAVM). This study aims to validate the vessel-selective MRA using time-spatial labeling inversion pulse. The pulmonary vessel or aorta could be intendedly selected with a high intensity against the surrounding anatomies. The contrast between vessels were evaluated using an ROI approach.
