Abstract:
Objective To compare the sensitivity and diagnostic features of mammogram (MG) and magnetic resonance imaging (MRI) on diagnosis of breast ductal carcinoma in situ (DCIS) with or without microinvasion (DCIS-MI).Methods From Jan 2012 to Nov 2013,results of MG and MRI from 72 cases of DCIS or DCIS-MI were retrospectively analyzed.Results The sensitivity of MG was 52.8% (38/72).The sensitivity of MRI was 87.5% (63/72),among those 76.2% (48/63)lesions presented as non-mass-like enhancement.Sensitivity of MRI was significantly higher in DCIS-MI than DCIS (84.6% vs 100%,P =0.027).Logistic regression analysis showed calcifications was an independent factor influencing the sensitivity of MG (OR =23.785,P < 0.001).Conclusions The sensitivity of MRI is higher than MG for the diagnosis of DCIS and DCIS-MI.
