Time-resolved fluorescence of normal and atherosclerotic arteries

摘要

Picosecond time-resolved fluorescence measurements were performed on fibrous and calcified atherosclerotic plaque and normal coronary artery with 351nm picosecond excitation of a mode-locked Nd-glass laser. Double exponential decay profiles were measured. The fast component of lifetimes of fibrous plaque is different than that of normal artery or calcified plaque and can be used to discriminate fibrous plaque from normal artery.
