Abstract
The goal of the study described here was to compare the accuracy of an automated breast volume scanner ABVS with that of hand held ultrasound HHUS in assessing the pre operative extent of pure ductal carcinoma in situ DCIS This prospective study consisted of 33 patients with histopathologically proven pure DCIS who received conventional HHUS and ABVS examinations The discrepancy and correlation coefficients were calculated to assess differences in sizes determined by imaging and histopathologic examination Mean age was 51 8 y Mean lesion size as assessed with the ABVS did not differ significantly from that determined by histopathology Lesion size was adequately estimated under estimated or over estimated with the ABVS in 64 15 and 21 of patients and with HHUS in 42 15 and 42 respectively p Under 0 05 The coefficient of correlation between histopathologic and ABVS measurements was higher than that between histopathologic and HHUS measurements The ABVS appears to assess the extent of the lesion better than HHUS and can provide more accurate information pre operatively
