摘要: 探讨磁共振IVIM成像预测直肠癌TN分期、分化、脉管侵犯的应用价值。对43例直肠癌患者行常规MRI及IVIM扫描,经后处理软件获得IVIM参数,病灶于一周内手术并送病理检查。随着T分期增加,D值减低、D*值升高(P<0.05);直肠腺癌病理分化程度越低,D值越低,D*值越高(P<0.05);D值在直肠癌有无淋巴结转移两组间差异有统计学意义(P<0.05);IVIM各参数在直肠癌有无脉管侵犯两组间无统计学意义(P>0.05)。因此,D值、D*值可以辅助直肠癌T分期,并能预测直肠癌病理分化程度,D值可以辅助诊断直肠癌是否发生淋巴结转移。

Abstract: To explore the value of magnetic resonance IVIM imaging in the prediction of TN staging, differentiation and vascular invasion of rectal cancer. Routine MRI and IVIM scanning were performed in 43 patients with rectal cancer. The IVIM parameters of the lesions were obtained and analyzed by post-processing software, then surgeries were performed within one week and the tumors were sent for pathological examination. As the T stage increased, the D value decreased and the D* value increased (P<0.05).The lower the pathological differentiation degree of rectal adenocarcinoma, the lower the D value and the higher the D* value (P<0.05).The D value was statistically significant between the two groups of rectal cancer with or without lymph node metastasis(P<0.05).The IVIM parameters were not statistically significant between the two groups with or without vascular invasion of rectal cancer (P>0.05). Therefore,D and D* value can assist in the T staging of rectal cancer and predict the degree of pathological differentiation. D value is also useful in the diagnosis of lymph node metastasis.
