Gynecologic fluoroscopy refers to colposcopy, which can be magnified 40 times and is used to visualize lesions in the vagina and cervix, especially in the cervix, which is more commonly used. When a woman suspects chronic cervical inflammation or cervical malignancy, colposcopy can be used to increase the positive rate of diagnosis based on the presence of blood vessels, heterogeneous changes in cellular tissue, etc. A multi-point biopsy can assist in the diagnosis. Colposcopy is a cold light source that can be used like a searchlight to observe the vagina and cervix, making it easier to visualize the lesion. It is also important to have a routine white belt test before the examination so as not to rule out acute inflammation of the vagina, which can adversely affect the results.
