Digital imaging colposcopy, image analysis and quantification of the colposcopic image

Objective To investigate the use of a digital imaging system for colposcopy, its use for image analysis and quantification of the colposcopic features that may predict histological outcome as defined by large loop excision of transformation zone. Design Prospective programme study of all patients undergoing colposcopy for cytological abnormalities. Setting Dudley Road Hospital, Birmingham. Subjects Fifty consecutive patients having cytological and colposcopic abnormality treated with large loop excision of transformation zone formed the study group. Main outcome measures Pretreatment and colposcopic features correlated with histological diagnosis of excised transformation zone
