目的分析CT三期动态增强扫描及多平面重建(MPR)技术在胃癌中的评估价值。方法收集2018年9月至2021年9月濮阳市油田总医院经手术病理检查确诊的126例胃癌患者的临床资料进行回顾性分析,患者入院时均接受CT三期动态增强扫描及MPR技术检查,以术后病理结果为金标准,分析CT三期动态增强扫描及MPR技术对胃癌患者术前的肿瘤侵犯程度及淋巴结转移情况的诊断价值。结果126胃癌患者病理检查结果显示:肿瘤侵犯程度Tis期15例,占11.90%;T 1期23例,占18.25%;T 2期26例,占20.63%;T 3期38例,占30.15%;T 4期24例,占19.05%。淋巴结转移N 0期31例,占24.60%;N 1期43例,占34.13%;N 2期33例,占26.19%;N 3期19例,占15.08%。以术后病理结果为金标准,CT三期动态增强扫描及MPR技术检查对胃癌术前肿瘤侵犯程度诊断的总符合率为95.24%(120/126),对胃癌术前淋巴结转移情况诊断的总符合率为75.40%(95/126),经Kappa一致性度量,其检查胃癌术前肿瘤侵犯程度的结果与术后病理结果的一致性较好(Kappa=0.939,P<0.001);CT三期动态增强扫描及MPR技术检查胃癌术前淋巴结转移结果与术后病理结果的一致性一般(Kappa=0.666,P<0.001)。结论CT三期动态增强扫描及MPR技术对胃癌患者术前的肿瘤侵犯程度及淋巴结转移情况均具有诊断价值,其检查肿瘤侵犯程度结果与术后病理检查结果的一致性较好,淋巴结转移情况与病理检查结果的一致性一般。
Objective To analyze the evaluation value of three-phase dynamic enhanced CT scanning and multiplanar reconstruction(MPR)in gastric cancer.Methods The clinical data of 126 patients with gastric cancer diagnosed by surgical and pathological examination in Puyang Oilfield General Hospital from September 2018 to September 2021 were retrospectively analyzed.All patients received three-phase dynamic enhanced CT scanning and MPR technology at admission.Taking the postoperative pathological results as the gold standard,the diagnostic value of three-phase dynamic enhanced CT scanning and MPR technology for preoperative tumor invasion and lymph node metastasis of gastric cancer patients was analyzed.Results The pathological examination results of 126 patients with gastric cancer showed that the degree of tumor invasion in Tis stage was 15 cases,accounting for 11.90%.There were 23 cases of T 1 stage,accounting for 18.25%,T 2 stage 26 cases,accounting for 20.63%,38 cases of T 3 stage,accounting for 30.15%,and there were 24 cases of T 4 stage,accounting for 19.05%.There were 31 cases of lymph node metastasis in N 0 stage,accounting for 24.60%,43 cases of N 1 stage,accounting for 34.13%,33 cases of N 2 stage,accounting for 26.19%,and there were 19 cases of N 3 stage,accounting for 15.08%.Taking the postoperative pathological results as the gold standard,the total coincidence rate of CT three-phase dynamic enhanced scanning and MPR technology in the diagnosis of preoperative tumor invasion of gastric cancer was 95.24%(120/126),and the total coincidence rate of preoperative lymph node metastasis of gastric cancer was 75.40%(95/126).Kappa consistency measure showed that the results of preoperative tumor invasion of gastric cancer were consistent with postoperative pathological results(Kappa=0.939,P<0.001).The results of preoperative lymph node metastasis by three-phase dynamic enhanced CT and MPR were generally consistent with postoperative pathological results(Kappa=0.666,P<0.001).Conclusion Three-phase dynamic enhanced CT scanning and MPR technology have diagnostic value for preoperative tumor invasion and lymph node metastasis in patients with gastric cancer.The results of tumor invasion are consistent with the results of postoperative pathological examination,and the consistency of lymph node metastasis and pathological examination is general.
