A new segmentation algorithm based on an active contour model at multiple scales, using the Gaussian Pyramid is performed on colposcopic images. The segmentation outlines a specific feature from the cervical images the Transformation Zone. A new snake the boundarysearching snake, based on both image gradient features and region features is implemented, starting from the low image resolution lev...

PURPOSE We sought to assess colposcopic proficiency in a family practice teaching clinic. METHODS Subjects were a prospective cohort of women age 13 to 68 who were colposcopy clinic attendees from 1991 to 2002. Data recorded on each subject included demographic variables, sexual history, history of sexually transmitted diseases, reason for referral to colposcopy, Pap smear results, colposcopi...

Colposcopy is a primary diagnostic method used to detect cancer and precancerous lesions of the uterine cervix. During the examination, the metaplastic and abnormal tissues exhibit different degrees of whiteness (acetowhitening effect) after applying a 3%-5% acetic acid solution. Colposcopists evaluate the color and density of the acetowhite tissue to assess the severity of lesions for the purp...

Objective To evaluate the diagnostic accuracy of the 2011 International Federation for Cervical Pathology and Colposcopy (IFCPC) colposcopic terminology. Methods The clinicopathological data of 2262 patients who underwent colposcopy from September 2012 to September 2016 were reviewed. The colposcopic findings, colposcopic impression, and cervical histopathology of the patients were analyzed. ...

For women who have abnormal Pap test results, the biopsy under colposcopic evaluation is the gold standard for determining the treatment modality. To increase the effectiveness of colposcopic communication, the International Federation for Cervical Pathology and Colposcopy (IFCPC) recently published fourth new nomenclature, aiming to create an evidence-based terminology. To increase the diagnos...

CORRELATION OF COLPOSCOPIC EXAMINATION RESULTS WITH HISTOPATHOLOGICAL FINDINGS AND ITS DIAGNOSTIC VALUE IN CERVICAL BIOPSY

As acetic acid-aided visual inspection (VIA) and colposcopic-directed biopsy miss small >/=cervical intraepithelial neoplasia (CIN) 2, inflation of sensitivity of VIA may occur when colposcopic-directed biopsy is the gold standard for >/=CIN 2. To determine whether such inflation occurs, we reviewed 375 women with >/=CIN 2 from the Shanxi Province Cervical Cancer Screening Study II. These women...

As the newest colposcopic terminology, the 2011 International Federation for Cervical Pathology and Colposcopy (IFCPC) classification provides standardized interpretation of colposcopic findings. In this study, we analyzed the colposcopic accuracy and the significance of individual findings according to the 2011 IFCPC classification in 525 patients, reviewed by 13 trained colposcopists. Results...

We present a fiber optic confocal reflectance microscope (FCRM) which can be used to image epithelial tissue with sub-cellular resolution in vivo. Confocal images of normal and abnormal appearing cervical tissue were obtained in vivo from eighteen patients undergoing colposcopic examination of the cervix; biopsy specimens were taken from imaged sites. The measured lateral and axial resolutions ...
