Abstract

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.
