Abstract: This prospective study was undertaken to assess the usefulness of ultrasound colour flow mapping in differentiating between benign and malignant ovarian cysts. In 1991, 61 patients with ovarian cysts had ultrasound scanning and colour flow mapping at the University Department of Obstetrics and Gynaecology in Singapore. These cysts were classified ultrasonically into simple cysts, complex cysts, complex cysts with solid areas and solid cysts. All the ovarian cysts were removed surgically and their nature confirmed histologically. The sensitivity and specificity of colour flow mapping in identifying malignant ovarian tumours was 67 and 82 per cent respectively. Positive and negative predictive values were 47 and 91 per cent respectively. For the solid ovarian cysts and complex cysts with solid areas, all the malignant ovarian tumours could be identified by colour flow mapping. Colour flow mapping missed malignancies in 66 per cent of the complex cysts without solid areas and in all of the simple cysts.
