Effect of different scanning threshold triggers on the image quality of brain computed tomography angiography: a randomized controlled trial
For brain CTA imaging in DLCT (50 keV VMIs), lowering the scan trigger threshold to 60 HU helped to reduce venous artifacts and improve image quality (as evidenced by improved subjective scores) and also suggests the potential for a further reduction of the contrast dose.
