Clinical Study
The Role of Magnetic Resonance Imaging in Preoperative Planning for Patients Undergoing Therapeutic Mammoplasty
| | | MRI findings | Findings on further investigation | Effect on surgical management |
| | 1 | Focal 10 mm tumour on conventional imaging but mixed intraductal/lobular; MRI was performed where 2 satellite lesions were noted | 2nd look USS—one C4 lesion, other B2 but not diagnostic | 3 tumours excised all within primary specimen (10, 2, and 1 mm) |
| | 2 | MRI identified additional lesion not seen initially | 2nd look USS identified second lesion, diagnostic biopsy—B1. On excision—B5b | Main 14 mm tumour mass with separate 1.2 mm satellite lesion (whole tumour 21 mm) |
| | 3 | MRI showed initial 9 mm tumour with further suspicious nodule 3 cm away | 2nd nodule not seen on second look USS. Diagnostic biopsy—B5b | Nodule included in resection specimen allowing successful single-stage surgery |
| | 4 | MRI confirmed 12 mm mass and suggested second lesion | 2nd look USS could not clearly identify lesion but fine needle aspirate—C3 (fibroadenoma with atypia) | 13 mm invasive tumour with second nodule confirmed benign lesion (fibroadenoma) |
| | 5 | MRI suggested extent of disease greater than that suggested by conventional imaging. It was also suggestive of a lesion in the contralateral breast | Second look USS—normal | No impact |
