研究目的:

1、主要研究目的:比较高清电子放大内窥镜结合图像增强技术与阴道镜对宫颈及阴道病变的检查准确率。 2、次要研究目的:评估并比较两种检查的灵敏度、特异度、阳性预测值、阴性预测值,评价两种检查在图像(如病变边界清晰度、微血管结构可视化)上的差异。  

Objectives of Study:

1. Primary Objective: To compare the diagnostic accuracy of high-definition electronic magnifying endoscopy combined with image-enhanced technology versus colposcopy for cervical and vaginal lesions. 2. Secondary Objectives: To evaluate and compare the sensitivity, specificity, positive predictive value, and negative predictive value of the two examination methods, and to assess the differences between the two techniques in image characteristics, such as lesion border clarity and visualization of microvascular structures.
