The efficacy of breast MRI in predicting breast conservation therapy

Abstract

Breast MRI does change surgical management by detecting additional malignancies. Breast MRI is accurate in staging extent of disease in the breast in patients with HG tumors.

Influence of preoperative MRI on the surgical management of patients with operable breast cancer

“…MRI is most accurate in staging the extent of breast cancer [38]. In our analyses the evidence of an extensive in situ component detected by MRI enabled the surgeon to complete a more precise breast conservation surgery in three cases, thereby potentially limiting re-excision procedures by avoiding microscopic involved resection margins.…”

Segmental enhancement on breast MR images: differential diagnosis and diagnostic strategy

“…Many published reports have revealed the high sensitivity of MRI for detecting disease extent [1][2][3][4][5][6]; however, specificity as low as 37% has been known [7] and careful analysis of the architectural features demonstrated on MRI is important to distinguish between benign and malignant disease [8,9].…”

Cost-Effective Staging of Breast Cancer

“…[6][7][8][9][10] Whereas mammography and ultrasound may underestimate tumor size, particularly in very dense breasts, MRI is associated with more accurate correlation with fi nal pathologic size. 9,11,12 Histologic differences within breast cancer may impact the added usefulness of MRI. Invasive lobular carcinoma (ILC) is notorious for being occult with standard imaging.…”

“…High-grade tumors correlated with pathologic tumor size; however, low-grade tumors had signifi cantly poorer correlation with pathologic size and were overestimated in their extent in 13% of cases. 12 In addition to evaluation of tumor size, MRI of the affected breast can improve preoperative detection of mammographic and clinically occult tumor foci distinct from the index lesion. Multifocality and multicentricity have been reported in 16% to 37% of cases in which preoperative MRI was added to conventional radiologic studies, with the MRI result changing surgical management in 11% to 14%.…”
