1、3. 0T磁共振动态增强扫描联合弥散加权成像评估胃癌术前TNM分期的临床价值包权 邢健 梁海昱 杨俊强 刘子航 沙如玉 李洪义Summary目的探讨磁共振MR动态增强扫描联合弥散加权成像对胃癌患者进行术前TNM分期的临床应用价值。方法 使用3.0T飞利浦MRI磁共振机行动态增强及弥散加权成像,对2016年10月2018年9月于我科行磁共振扫描并经手术病理证实胃癌的39例患者术前进行TNM分期,以手街病理分期结果为金标准对照磁共振诊断结果一致性,并进行卡方检验。结果本研究39例胃癌患者中MRI诊断为T1期2例,T2期10例,T3期11例,T4期16例;病理诊断T1期6例,T2期6例,T3期9例,
2、T4期18例。39例患者N分期结果为MRI诊断为N0期11例,N1期12例,N2期16例;病理诊断N0期10例,N1期14例,N2期15例。M分期中MRI诊断M0期30例,Ml期9例;病理诊断M0期30例,Ml期9例。39例胃癌患者MRI综合评估T、N、M分期准确性分别为69. 23%、71.79%, 89. 74%o结论MRI动态增强扫描联合弥散加权成像对胃癌术前TNM分期具有一定优势,且M分期具有较高准确性。Key胃癌;动态增强扫描;弥散加权成像;TNM分期;病理分期口 R735. 2;R445. 2 口 B 1673-9701 (2019) 28-0116-05Abstract Obje
3、ctive To evaluate the clinical value of magneticresonance MR dynamic contrast-enhanced scan combined with diffusion-weighted imaging in preoperative TNM staging of gastric cancerpatients. Methods The 3. 0T Philips MRI magnetic resonance machine wasused for dynamic enhancement and diffusion-weighted
4、imaging. TNMstaging was performed preoperatively in 39 patients who underwentmagnetic resonance imaging and were pathologically confirmed withgastric cancer in our department from October 2016 to September 2018.The results of surgical pathological staging were used as the goldstandard for the consis
5、tency of magnetic resonance diagnosis results.And the chi-square test was performed. Results In this study, among39 patients with gastric cancer, there were 2 cases of Tl, 10 casesof T2, 11 cases of T3, and 16 cases of T4. There were 6 cases ofT1, 6 cases of T2, 9 cases of T3, and 18 cases of T4 by
6、pathologicaldiagnosis. The N-stage results of 39 patients showed that there were11 cases of NO, 12 cases of Nl, and 16 cases of N2. There were 10cases of NO, 14 cases of Nl, 15 cases of N2 by pathologicaldiagnosis. In M stage, there were 30 cases of M0 stage and 9 casesof Ml stage. There were 30 cas
