Clinical applications of magnetic resonance angiography.
The development of MRA 2D TOF or 3D TOF and its implementation in extracranial and intracranial circulation has defined some clinical applications. However, when deciding to use MRA study some intrinsic aspects must be considered about the quality that varies from site to site owing to differences in technique, and artefactual signal loss, flow variations that can be misdiagnosed. There is no question that MRA can provide useful anatomic and physiologic information about the cerebral circulation, also as good screening tool for the setting of extracranial carotid disease.
