What frame rate is typically used for arterial imaging in TACE/SIRT?

In transarterial chemoembolization (TACE) and selective internal radiation therapy (SIRT), vascular imaging is crucial for visualizing blood flow and end-organ perfusion during procedures. The frame rate selected for arterial imaging is important as it must balance capturing sufficient detail with maintaining a manageable data load.

A frame rate of 3-4 frames per second is typically used during these procedures because it provides a clear representation of dynamic changes in blood flow without overwhelming the viewer with too many images. This rate enables practitioners to visualize the contrast agent's movement through the arteries effectively, allowing for timely and accurate assessment of perfusion and any potential complications.

Utilizing a frame rate higher than 4 frames per second could result in excessive data and might not significantly improve the clarity of the imaging, while a lower rate could lead to missed critical information regarding blood flow patterns. Therefore, the 3-4 fps range is preferred as it optimally balances clarity and efficiency in arterial imaging during TACE and SIRT interventions.
