Optimized 4D time‐of‐flight MR angiography using saturation pulse

To assess arterial visibility on 4D time‐of‐flight (4D‐TOF) by temporal magnetization transfer contrast pulse (t‐MTC) and temporal tilted optimized nonsaturating excitation (t‐TONE). 3D‐TOF magnetic resonance angiography (MRA) is used for the noninvasive assessment of the intracranial arteries. However, it does not provide temporal information for diagnosing hemodynamics. To noninvasively obtain more detailed hemodynamics‐related information, we developed a novel time‐resolved MRA without the arterial spin labeling technique, termed 4D‐TOF MRA using saturation pulse.
