Abstract: Two types of MR angiography techniques are used in the radiological practice for neurovascular applications: flow based techniques and ultrafast contrast enhanced acquisitions. Both techniques have their specific advantages and limitations. Whereas flow based techniques can be run on most MR scanners, high quality contrast enhanced studies require a state-of-the-art system with high slew rates and dedicated tools to match bolus passage and MR scanning. In this text, we focus on the physical acquisition principles and we illustrate the different phenomena in clinical examples. Numerous studies have proven the clinical applications for the 2 acquisition strategies. So far, an understanding of the basic physics remains necessary to explain occasional artefacts: MR angiography techniques are not yet fully robust. Further optimizations of the current approaches can be expected as there is still a need to improve image quality.
