摘要/Abstract

摘要： 将2017年1月至2018年12月于西宁市第二人民医院行新辅助治疗的72例胃癌患者纳入研究，同时给予患者超声造影（contrast-enhanced ultrasonography，CEUS）检查及磁共振成像（magnetic resonance imaging，MRI）增强扫描，比较并分析二者对治疗后分期及肿瘤周围侵犯情况的检查结果，以探究CEUS在评估胃癌新辅助治疗后分期及侵犯情况方面与MRI的一致性。研究结果显示，MRI和CEUS评估胃癌T分期的诊断一致率为91.67%，具有较高一致性；CEUS和MRI评估病灶的左右径、纵轴直径和前后径具有较好的一致性，且两者无明显差异；CEUS与MRI评估其侵袭横结肠及其系膜、肝/脾、十二指肠/胰腺的诊断，具有较高的一致性。本研究证实，CEUS与MRI在评估胃癌T分期、病灶大小及周围组织侵犯情况时结果基本一致。

Abstract: 72 patients with gastric cancer who underwent neoadjuvant therapy in our hospital from January 2017 to December 2018 were enrolled in the study, contrast-enhanced ultrasonography (CEUS) and magnetic resonance imaging (MRI) enhanced scanning were performed simultaneously. 132 We compared and analyzed the consistency of the two tests on post-treatment staging and surrounding violations, and explored the consistency of CEUS in assessing the staging and invasion of gastric cancer after neoadjuvant therapy. The results of the study showed, the diagnostic agreement rate for MRI and CEUS assessment of gastric cancer T staging was 91.67%, which has the high consistency; MRI and CEUS have a high agreement in left and right diameter, longitudinal axis diameter and anteroposterior diameter of the lesions,and there was no significant difference between two methods. The diagnostic agreement rates of CEUS and MRI for the invasion of the transverse colon and its mesentery, liver/spleen, duodenum/pancreas have a high consistency. This study confirmed that CEUS and MRI have a high consistency in the assessment of gastric cancer T stage, lesion size and surrounding tissue invasion.
