Cervicography uses photography to identify squamous intraepithelial lesions.The examiner first applies a 5% acetic acid solution, then photographs
the cervix using a 35-mm camera. The resulting slide, a cervicogram, is
interpreted by an experienced colposcopist. Cervicography is less expensive
than colposcopy but has limited usefulness because up to 40% cannot be
evaluated owing to technical problems or inadequate visualization of the
transformation zone. When adequate for interpretation, the cervicogram’s
reported sensitivity ranges between 74% and 94%, but the test’s specificity
is only 26% to 50%. Although available since 1981, cervicography is not
currently used in screening for cervical neoplasia (Appleby).
