| ［摘要］ 淋巴结转移是影响胃癌患者预后的重要危险因素之一。病理活检是目前现有的检查手段中唯一可以确诊淋巴结转移阳性的方式，而胃周淋巴结分布广泛且解剖位置多变，术前对淋巴结进行活检较为困难。现有的检查方式中，无论是超声内镜(EUS)、多排螺旋CT（MDCT）还是核磁共振成像（MRI），对于淋巴结转移的诊断目前都是停留在形态学方面。该文对胃癌淋巴结转移的分期与影像学诊断研究进展进行综述。 |

| Abstract: |
| ［Abstract］ Lymph node metastasis is one of the important risk factors affecting the prognosis of gastric cancer patients. Currently, pathological biopsy is the only examination method that can confirm the positive lymph node metastasis. However, the perigastric lymph nodes are widely distributed and their anatomical positions are variable. Therefore, it is difficult to conduct biopsy of lymph nodes before operation. Among the existing examination methods, whether endoscopic ultrasound(EUS), multidetector-row computed tomography(MDCT) or magnetic resonance imaging(MRI), the diagnosis of lymph node metastasis is currently based on morphology. This paper reviews the research progress of imaging diagnosis and staging of lymph node metastasis of gastric cancer. |
