Figure Lengend Snippet: Spectroscopy of the aorta and ventricular myocardium from a rat. ( A ) Raw reflectance spectra from live aorta and live ventricular myocardium. The spectra were pronouncedly different. In particular, the spectrum from the myocardium exhibited smaller intensities than the spectrum from the aorta. ( B ) Differences between raw spectra from the myocardium before and after 15 min of fixation with paraformaldehyde were marginal. ( C , D ) Signal-to-noise ratio (SNR) for collection fibers R1 to R5 and various sampling rates measured using the ( C ) calibration standard and ( D ) fixed ventricular tissue.
