重视脑转移瘤标准化影像检查以提高影像评估准确性

Emphasis on standardized imaging examination of brain metastases to improve the accuracy of imaging evaluation

随着靶向、免疫等新治疗方法的出现,系统肿瘤诊治水平不断提高。这一方面带来患者生存期延长,但同时中枢神经系统转移肿瘤发病率上升。脑转移瘤的治疗决策,除了和原发肿瘤类型相关外,一个重要依据就是病灶数目。MRI已成为显示脑转移瘤首选检查方法,但显示病灶能力、数目和很多因素相关。标准化的影像检查,不仅能提高诊断准确性,更能为患者治疗决策和评估提供最直观和可靠的依据。

With the emergence of new treatment such as tumor-targeting and immunotherapy,the overall survival time of systemic tumor patients continues to prolong.However,the incidence of central nervous system metastatic tumors increases at the same time.The treatment decision for brain metastases is based mainly on the number of lesions,beside the type of primary tumor.Currently,there is agreement that MRI is becoming the first choice for both detection and counting of the number of brain metastatic lesions.The ability of MRI for demonstrating metastatic lesions is related to many factors.Standardized imaging examination can not only improve the accuracy of diagnosis,but also provide the most reliable basis for treatment decision-making and evaluation.
