The value of diagnosis and preoperative evaluation of breast cancer by multi-detector-row CT

Abstract

Objective To evaluate the accuracy of multi-detector-row CT （MDCT） in the diagnosis and preoperative evaluation of breast cancer. Methods From January 2004 to December 2007,the clinical data of 54 cases wih pathologically proved breast cancer undergoing preoperative MDCT scan （31 cases also underwent MRI scan） were retrospectively analyzed at our hospital. Surgical planning was based on MDCT assessment. The extent and location of tumor depicted by MDCT,MRI and pathology were compared. Results Breast carcinoma was diagnosed by MDCT in all the cases. In these 54 patients,MDCT achived an accuracy of 87% in evaluating the extent of tumor. Based on MDCT,39 cases underwent BCT surgery with a 8% margin positive rate. MDCT and MRI had no significant difference in accuracy of evaluation on the extent of tumor （ x2 = 0. 5, P 〉 0. 05 ）. Conclusions MDCT accurately assesses the extent and location of breast cancer, proving its value in preoperative evaluation of breast cancer.
