摘要
目的:探讨动态增强磁共振成像(magnetic resonance imaging,MRI)在乳腺癌保乳手术中的应用价值。方法:选择保乳手术治疗并经病理证实的乳腺癌患者54例。术前均行动态增强MRI检查,观察病灶的位置、大小和强化类型等,并与术后病理学诊断结果相对照。结果:手术后病理学检查发现54个病灶。动态增强MRI对病灶的检出率为100%,对病灶的定位与病理学诊断结果完全符合;对病灶大小的测量与病理学诊断结果具有较高的一致性(P<0.05);不均匀强化的病灶多为低分化癌(13/19)。结论:动态增强MRI可评估乳腺癌保乳手术的可能性和预后,具有重要的临床应用价值。
Objective:To explore the clinical value of dynamic contrast magnetic resonance imaging (MRI)in breast-conserving surgery.Methods:A total of 54 pathologically confirmed breast cancer patients who received breast-conserving surgery were chosen.All cases were examined by dynamic contrast MRI before operation.Results:54 lesions were confirmed by pathology after operation.The detection rate of dynamic contrast MRI was 100%.Lesion localization detected by dynamic contrast MR1was completely in accord with pathological results.Lesion size detected by dynamic contrast MRI had high consistency with pathological results (P<0.05).The lesions with heterogeneous enhancement were mostly poorly differentiated carcinoma (13/19).Conclusion: Dynamic contrast MRI has significant clinical value in the evaluation of operation feasibility and prognosis of breast-conserving surgery.
