"The anteroposterior diameter of the lateral ventricle index (ALVI) is a quantitative metric to evaluate the size of the lateral ventricles, particularly in normal pressure hydrocephalus."

Line 1:73 · 'ALVI' has no definition. Spell it out if it's unfamiliar to the audience.

"Importantly the measurement of ALVI does not involve measuring the maximum diameter from multiple adjacent axial slices as is the case for the Evans index. As a result, the ALVI measurement technique is thought to be more reproducible and faster ^1,2."

"The ALVI is calculated on axial images obtained or reconstructed in the AC-PC plane. The most inferior axial image is chosen where the entire body of the lateral ventricle is visible without being obscured by the thalamus ¹."
