Role of colour doppler sonography in the diagnosis of breast tumors

Objective: to determine efficacy of doppler sonography in diagnosis of breast tumours on the basis of resistive index (ri),and pulsatility index (pi) values using histopathology as gold standard. duration: the study was completed over a period of six months,from 27-03-2007 to 26-09-2007. methods: fifty consecutive patients with breast mass suspected clinically were included. these cases were subjected to clinical examination. gray scale ultrasound was performed to evaluate margins of the lesion,surrounding halo,echogenecity and calcification. doppler ultrasound was done to see blood flow in the lesion calculate ri and pi. results: mean age of the patients was 38.8±12.7 years. sensitivity,specificity,and diagnostic accuracy of colour doppler sonography was observed 91.6%,84.6% and 88.0%,respectively. positive predictive value of colour doppler sonography was found to be 84.6% and negative predictive value of colour doppler sonography was found to be 91.6%.
