Cervicography: a new method for cervical cancer detection

A new diagnostic method, cervicography, provides permanent, objective documentation of normal and abnormal cervical patterns. The projected cervicogram is comparable to direct visual colposcopic magnification and resolution. The cervicogram can be obtained by a technician and sent to an expert for evaluation. A study of 700 women was undertaken to compare the diagnostic accuracy of colposcopic, cytologic, and cervicographic findings. In 296 women with abnormal cytologic findings, 136 cases of dysplasia or carcinoma were diagnosed by directed biopsy. In 91.1%, both colposcopic and cervicographic findings were suspicious; 2.9% of the cases were detected solely by cervicography, and 5.9% were detected solely by colposcopy. In 404 routinely screened patients with no previous abnormal cytologic findings, nine cases (2.2%) of dysplasia were detected solely as a result of cervicographic screening.
