Caution advised for histometric lumen sizing in contracted vessels; leaves open cross-sectional area as preferred metric in animal vascular models.
Does the histometric method accurately estimate relaxed lumen size compared to morphometric measurements in rat mesenteric arteries?
The histometric method underestimates relaxed lumen size in contracted vessels, suggesting cross-sectional area is a more accurate metric for comparing vessel wall dimensions in hypertensive models.
