Many new technologies have been introduced to enhance the diagnosis precision of colposcopy, objectively guide the biopsy site and assess the dysplastic condition of the epithelium. These include fluorescence spectroscopy, electrical impedance spectroscopy, diffuse reflectance spectroscopy, and/or variations thereof. Other technologies such as optical coherence tomography and polarimetric imaging have also been used to better define lesions. Not only have the adjunct use of technology, but also
