In the present paper,FT-mid-IR fiber optics spectroscopy was used to determine the thyroid tumor.A modified WQF-500 FTIR spectrometer with MCT detector and mid-IR fiber optics ATR accessory was used in this *** examination of the skin overlying the thyroid tumor was performed on five patients,in vivo detection and in vitro measurement of six patients in operation room was also carried *** experimental data indicate that malignant and benign thyroid tumor could be distinguished from the spectra of percutaneous examination,the in vivo measurement and freshly resected thyroid *** relative intensity and peak position of the IR bands in the region of 1 700-1 500 cm-1（amide Ⅰ and amide Ⅱ）,1 480-1 400 cm-1,and 1 320-1 200 cm-1 are reliable spectral marker or indexes for tumor *** results demonstrate that FT-mid-IR fiber optics spectroscopy exhibits prospect to develop a novel non-invasive method for thyroid tumor detection.
