The most frequently employed method for assessing the brain’s arterial blood supply system is the three-dimensional (3D) time-of-flight (TOF) MRA. This technique offers advantages such as improved signal-to-noise ratio and shorter imaging times.

What are the major TOF MR artifacts should we know about? At least 6 different artifacts are commonly noted in time-of-flight (TOF) MRA studies. These are illustrated and briefly discussed below: This simplest form of this artifact is a subtle pixelated appearance to …

As the name implies TOF MRA is based the principle of flow-related enhancement, a time-of-flight flow phenomenon discussed in a prior Q&A. Stationary tissues in an imaged volume become magnetically saturated by multiple repetitive RF-pulses that drive down their steady-state magnetization levels.

Time-of-Flight Magnetic Resonance Angiography (TOF MRA) is a specialized imaging technique within the realm of magnetic resonance imaging (MRI) that focuses on visualizing blood vessels and blood flow dynamics without the need for contrast agents.

o EPIC: [adult brain] [with and without contrast] [MRA COW (TOF)] o Routine aneurysm f/u: noncontrast MRA only. AVMs and HHT: add ASL, MRA to cover entire head. -Brain infection (meningitis, abscess, empyema); neurocutaneous syndromes; mitochondrial and metabolic disease o Order name: MRI BRAIN W WO CONTRAST IV contrast: Yes

Feb 7, 2020 · - Use 3D TOF, 3 slabs. Send 1mm axial source images and post processing 3D volumetric MIPs of full volume, anterior circulation and posterior circulation rotating in axial plane and sagittal planes. - Place saturation band above axial block to reduce venous contamination.
