Capsaicin‐induced mucus secretion in rat airways assessed<i>in vivo</i>and non‐invasively by magnetic resonance imaging

Abstract

These observations suggest that the fluid signals detected by MRI after capsaicin administration reflected predominantly the release of mucus following activation of sensory nerves. They point to the opportunity of non-invasively assessing with MRI the influence of neuronal mechanisms in animal models of asthma and COPD.
