Asymmetries of total arterial supply of cerebral hemispheres do not exist.

ABSTRACT:

Background

Total blood supply to an organ, or its part, is proportional to its function. The aim of this project was to investigate whether there is a lateralisation of total functions of cerebral hemispheres by determining differences in the arterial blood supply to left and right cerebral hemispheres.

Methods

Diameters of right and left anterior, middle and posterior cerebral arteries were measured at specific sites and cross-sectional areas calculated in 203 adult brains (51 donated and dissected brain specimens and 152 cerebral arterial Computed Tomography Angiography and Magnetic Resonance Angiography images).

Findings

The sample size was large enough to provide a power of detecting as significant differences of 4%, but neither of the average cross-sectional area
