依据和目标：目的：评价磁共振成像（MRI）在乳腺癌术前提供局部信息中的作用。采用1.5T磁共振成像系统，采用SPGR脉冲序列，行脂肪抑制T1 WI、T2 WI及动态增强扫描。结果：从MRM获得的大小与组织学获得的大小，包括导管内扩散的癌症（R：0.853），以及与MRM测量的癌症的程度证实在所有patients.RESULTS：相关。至于形状，从MRM明显的圆形/椭圆形的相关性更准确（R：0.934）比不明确的类型与线性和/或团块状增强区（R：0.744）。在大多数患者（93.5%）中，从MRM获得的大小和组织学获得的大小（包括IDS）之间的差异小于15 mm。结论：MRM准确地揭示了癌症的程度，包括IDS，并有效地为乳腺癌的保乳治疗提供术前局部信息。
RATIONALE AND OBJECTIVES: To assess the efficacy of MRM in providing preoperative locoregional information on patients with breast cancer.METHODS: MRI was performed on 62 female breast cancer patients. A 1.5T MR-system was used to acquire fat-suppressed T(1)WI, T(2)WI and dynamic-contrast-enhanced images with an SPGR pulse sequence. The extent of the cancer measured with MRM was confirmed histologically in all patients.RESULTS: The size obtained from MRM correlated well with the size obtained histologically, including intraductal spread of cancer (R: 0.853). As for shape, the round/oval type evident from MRM correlated more accurately (R: 0.934) than the ill-defined type associated with a linear and/or clumped enhanced area (R: 0.744). The difference between the size obtained from MRM and the size obtained histologically, including IDS, was less than 15 mm in the majority of patients (93.5%).CONCLUSIONS: MRM accurately reveals the extent of cancer, including IDS, and is effective at providing preoperative locoregional information for breast-conserving therapy for breast cancer.
