临床上往往对于某些粘膜损害,例如口腔上皮的浅表平伏性损害或者只表现为柔软的单纯的上皮粗糙等,由于这些损害既无浸润又无自发痛,从而忽视了这些损害的严重性,因此寻求一种比较简单可靠的方法,使能取代活检而迅速显示损害的性质:是否属于良性或者已发展为癌前状态或甚至癌变;而且还能为应取活检的部位提供一种选择性的依据,这种检查方法已越来越引起人们普遍的关注。 Clinically, some mucosal lesions are often caused, such as superficial equine lesions of the oral epithelium or only simple soft epithelial roughness. These lesions have neither infiltration nor spontaneous pain, thus neglecting the severity of these lesions. Therefore, a relatively simple and reliable method is sought to enable the rapid display of the nature of the damage in place of a biopsy: whether it is benign or has developed into a precancerous condition or even a cancerous condition; and it also provides a selective approach to the site where biopsy should be performed. Based on this, inspection methods have increasingly attracted people’s attention.
