WebIn-Plane Saturation Artifact. TOF MRA relies on the inflow of fresh (unsaturated) blood to produce high intravascular signal. This signal is highest whenever the direction of flow is perpendicular to the primary imaging plane. When vessels travel within plane, their blood may become saturated like stationary tissues, resulting in decreased ... WebJun 13, 2024 · Flow-related enhancement accounts for hyperintensity in the iliac veins, in this case. Remember that gradient echo images are time-of-flight images (without the parameter modifications of dedicated vascular sequences) and prone to the in-flow effect (especially in two-dimensional sequences in the case of the entry slice with respect to the ...

It is also noteworthy that bidirectional flow within a vertebral artery does not always indicate a subclavian steal and can be related to hypoplasia or stenosis of the verte-bral artery instead.7 TOF MR angiography utilizes the movement of blood to pro- WebNonetheless, a number of diagnostic clues can be garnered from the spin-echo images in equivocal cases. For instance, localizer images obtained using gradient-echo technique often show flow-related enhancement in dural sinuses (Figs. 2A and 2B).
