Presence of Anterior Communicating Artery Aneurysm Is Associated With Age, Bifurcation Angle, and Vessel Diameter.
TL;DR: The presence of Acom aneurysm is significantly associated with patient age, wider angles of the anterior cerebral artery bifurcation, and smaller vascular diameter of the posterior communicating complex.

TL;DR: On-site calculation of CTA-FFR can identify hemodynamically significant CAD with an overall per-vessel accuracy of 75% in comparison to invasive FFR, and is negatively affected by misalignment artifacts.

CHOROIDAL BLOOD FLOW: Review and Potential Explanation for the Choroidal Venous Anatomy Including the Vortex Vein System.
TL;DR: Control of blood flow is critical in the choroid, and this control appears to extend to the venous outflow system, which would have important impact on theories of many ocular diseases including central serous chorioretinopathy and spaceflight associated neuro-ocular syndrome.

TL;DR: Low WSS was independently associated with severe EDFx in patients with nonobstructive CAD, and segments with low WSS demonstrated more vasoconstriction in response to Ach than did intermediate or high WSS segments.

TL;DR: In this article, a scaling law that links length density, i.e., the length of vessel per volume, with tissue-to-vessel distances, was proposed to predict a common value of maximum tissue oxygen tension across the brain.
