傅里叶变换红外光谱体表无创探测乳腺肿瘤

Surface Noninvasive Detection of Breast Tumors Using Fourier Transform Infrared Spectroscopy

利用傅里叶变换红外(FTIR)光谱仪联合衰减全反射(ATR)探头的中红外光导纤维对46名健康志愿者及113名乳腺肿物患者的体表皮肤进行无创红外光谱测定,并从分子水平比较、分析了正常乳腺和有肿物乳腺体表皮肤的红外光谱特征.结果表明,健康志愿者乳房皮肤8个FTIR光谱测定部位的图谱趋于一致;正常乳腺体表与有肿瘤乳腺体表的吸收峰差异明显,而1080 cm-1处核酸相关吸收峰的变化对鉴别肿瘤的良、恶性有重要意义.

To identify Fourier transform infrared（FTIR） spectra of normal and abnormal（mass） breast skin at molecular level, infrared scanning was performed for 46 healthy volunteers and 113 inpatients with palpable breast masses. Breast surface were measured by FTIR spectrometer equipped with attenuated total reflectance（ATR） probe and infrared optical fiber. The results showed that the spectra of healthy volunteers tended to be consistent; the FTIR spectra of control, benign and malignant groups differed owing to content or configuration alterations of nucleic acids, proteins, lipids and carbohydrates, and changes in differential diagnosis of benign and malignant were predominantly observed in the 1080 cm-1 peak absorbance, commonly associated with nucleic acids.
