Superparamagnetic iron oxide (SPIO)-enhanced MRI at 1.5 T with fat-suppression sequence is useful for the detection of metastases in sentinel nodes localized by CT lymphography in patients with breast cancer. SPIO-enhanced MRI may offer an alternative to sentinel node biopsy and avoid axillary surgery itself for patients with breast cancer who have negative sentinel nodes on SPIO-enhanced MRI.

通过 1.5 T 超顺磁氧化铁增强 MRI 和脂肪抑制序列进行精确腋窝分期，作为乳腺癌前哨淋巴结活检的替代方案

具有脂肪抑制序列的 1.5 T 超顺磁性氧化铁 (SPIO) 增强 MRI 可用于检测乳腺癌患者通过 CT 淋巴成像定位的前哨淋巴结转移。SPIO 增强 MRI 可以提供前哨淋巴结活检的替代方案，对于 SPIO 增强 MRI 前哨淋巴结阴性的乳腺癌患者可以避免腋窝手术本身。
