Underestimation of DCIS at MRI-guided vacuum-assisted breast biopsy
Carcinoma in Situ
Carcinoma, Ductal, Breast
Underestimation occurred in 17% of lesions yielding DCIS and in 80% of lesions yielding DCIS with possible microinvasion at MRI vacuum-assisted breast biopsy. DCIS underestimation was significantly more likely in lesions measuring 6 cm or larger. No other patient or lesion factors significantly affected DCIS underestimation at MRI vacuum-assisted breast biopsy.
