MRIangio
MRIangio, or MR angiography (MRA), refers to magnetic resonance imaging techniques used to visualize blood vessels. It includes non-contrast methods such as time-of-flight (TOF) and phase-contrast sequences, as well as contrast-enhanced approaches that use gadolinium-based agents. Advanced variants, like time-resolved MRA and 4D flow imaging, provide dynamic information about blood movement in vessels.
MRIangio is employed to evaluate the cerebrovascular system (intracranial and carotid arteries), intracranial aneurysms and vascular
Advantages of MRIangio include the lack of ionizing radiation, excellent soft tissue contrast, and the ability
Limitations involve sensitivity to flow-related artifacts, motion, and certain implants or devices that may be contraindicated.
Post-processing commonly uses maximum intensity projection (MIP), multiplanar reformats, and sometimes volume rendering to create intuitive
