摘要
选取2017年8月~2019年2月我院收治的胃癌患者130例作为研究对象,依据患者病理诊断结果作为金标准,分析磁共振成像(magnetic resonance imaging,MRI)与超声双重造影对胃癌的诊断价值及术前T分期的价值。结果显示,超声双重造影共检出120例胃癌患者,出现10例漏诊,MRI共检出109例胃癌患者,出现21例漏诊。金标准共检出52例T1期、32例T2期、26例T3期、20例T4期患者,超声双重造影诊断出T1期48例,符合率92.31%;T2期30例,符合率93.75%;T3期24例,符合率92.31%;T4期18例,符合率90.00%,进一步分析显示,超声双重造影对不同胃癌T分期的诊断价值均高于MRI。因此,超声双重造影对胃癌的诊断价值及对术前T分期诊断价值均高于MRI。
130 patients with gastric cancer admitted to our hospital from August 2017 to February 2019 were selected as the research objects.According to the pathological diagnosis results of patients as the gold standard,the diagnostic value of magnetic resonance imaging(MRI)and ultrasound double contrast examination for gastric cancer and the value of T-staging before operation were analyzed.The results showed that 120 cases of gastric cancer were detected by double contrast ultrasound,10 cases were missed diagnosis,109 cases were detected by MRI,21 cases were missed diagnosis.52 cases of T1,32 cases of T2,26 cases of T3,and 20 cases of T4 were detected in the gold standard.48 cases of T1 were diagnosed by double contrast-enhanced ultrasound,the coincidence rate was 92.31%,30 cases of T2,the coincidence rate was 93.75%,24 cases of T3,the coincidence rate was 92.31%,18 cases of T4,the coincidence rate was 90.00%.Further analysis showed that the value of double contrast-enhanced ultrasonography in the diagnosis of different T stages of gastric cancer was higher than that of MRI.From the results of this study,we conclude that the value of double contrast-enhanced ultrasonography in the diagnosis of gastric cancer and T-staging before operation is higher than that of MRI.
