本院自1972年开始应用手电筒式荧光诊断仪检查早期子宫颈癌,发现荧光检查法的假阴性极低,但假阳性较高。自1978年起,开始利用氦-镉激光激发荧光进行光谱
In 1972, this hospital began to use a flashlight type fluorescent diagnostic apparatus to examine early cervical cancer and found that the false negative result of fluoroscopy was extremely low, but the false positive rate was high. Since 1978, the use of neon-cadmium laser to excite fluorescence has been used for spectroscopy
