英文摘要
The objective of this study is to show that Raman spectroscopy can
be used to evaluate the lipid and calcium salt contents of human
peripheral arteries. We studied 167 segments of carotid and femoral
artery wall in various pathological states. The Raman spectra from
these samples could be accurately modeled. The resulting chemical
concentrations were compared with the amounts of cholesterol and
calcium mineral determined by histological evaluation by an
experienced cardiovascular pathologist. Strong correlations between
the spectroscopic measurements and the morphological findings were
demonstrated, thus validating the applicability of the method to
peripheral arteries. Raman spectroscopy can provide reliable
histochemical information about peripheral, as well as coronary
arteries. Such information may help identify individuals with
rupture-prone plaques before the onset of symptoms, allowing
aggressive and directed intervention. Accurate knowledge of the chemi
cal composition of a lesion may also be useful in selecting the most
appropriate treatment modality.
