Value of multi-detector CT low tension dynamic enhanced scanning in preoperative evaluation of advanced gastric cancer / 肿瘤研究与临床

ABSTRACT

Objective To investigate the value of muhi-detector CT (MDCT) low tension dynamic enhanced scanning on the preoperative assessment of advanced gastric cancer.Methods MDCT low tension dynamic enhanced scanning,tumor diagnosis and staging and prediction of surgery operation were performed on 43 cases of advanced gastric cancer.And the above results were compared with pathology results.Results The 36 cases were treated with resection,while 7 cases were treated by gastrointestinal anastomosis.The MDCT had 76.7 ％ (33/43) of accuracy for the preoperative T staging and 74.4 ％ (32/43) of accuracy for the preoperative N staging,respectively.The stomach wall thickness was closely related to serosal invasion (x2 =20.170 9,P ＜ 0.001).Conclusions The MDCT low tension dynamic enhanced scanning can improve the comprehensiveness and accuracy of preoperative staging of T and N in advanced gastric cancer.It is valuable for the preoperative diagnosis and treatment of gastric cancer.
