Technical advances in MR angiography (MRA) have improved the sensitivity and the accuracy of this technique in the evaluation of vascular stenoocclusive disease of the brain. In many centers, due to its non-invasive and non-ionizing character, MR angiography has already replaced conventional angiography for the screening of intracranial vascular disease. Several MRA techniques have been developed for imaging the intracranial vascular system, such as time-of-flight MRA (TOF-MRA), phased-contrast MRA (PC-MRA), and more recently contrast-enhanced MRA (CEMRA).
