中文摘要：

膀胱癌是泌尿系统最常见的恶性肿瘤,易发生复发、转移。相对于淋巴结转移阴性的患者,淋巴结转移阳性的患者复发、转移概率更高,而且往往是致死性的。准确预测淋巴结转移与否对于患者治疗策略的选择具有重要指导意义。目前诊断淋巴结转移的金标准为术后病理,术前主要依靠影像学,但是准确性不太理想。本文就膀胱癌盆腔淋巴结转移的影像学诊断方法,包括CT、MRI及PET/CT、SPECT/CT及前哨淋巴结显像等作一综述。

英文摘要：

Bladder cancer is the most common tumor in urinary system in our country,and easy to recurrence and fast widespread of metastasis. Relative to negative lymph nodes,positive lymph nodes tend to recurrent and metastasize more often and once it happens it′s much more likely to be fatal. It is significantly instructive for the choice of the treatment strategies that predicts positive or negative lymph nodes precisely. At the moment,the gold standard diagnosis of lymph nodes metastases is pathological result after the surgery. Before the surgery,it′s mainly dependent on imaging with unsatisfactory accuracy.This passage would focus on the diagnostic methods of imaging in metastases in pelvic lymph nodes.
