| 摘 要： | 目的:探讨磁共振弥散加权成像(DWI)联合常规序列在直肠癌T分期中的应用价值。方法:分别应用常规序列、DWI及常规序列联合DWI对43例直肠癌患者进行术前T分期,并将影像观察结果与术后病理结果对照。结果:MRI常规序列联合DWI对直肠癌T分期与病理学分期有较高的一致性,常规序列、DWI及两者联合用于直肠癌T分期的总准确率分别为74.4%(32/43)、86.0%(37/43)、97.7%(42/43)。结论:DWI结合常规序列能够对直肠癌T分期做出较准确的判断。

| Abstract: | Aim:To evaluate the clinical value of diffusion weighted imaging(DWI) combined with in the T staging of rectal carcinoma.Methods:T staging was undertaken in 43 patients with rectal cancer by magnetic resonance imaging(MRI) conventional sequences,DWI,and DWI combined with MRI conventional sequences,respectively.All the results were compared with the pathological staging after surgery.Results:The tumor staging by DWI combined with MRI conventional sequences agreed with the pathological staging of rectal carcinoma.The total accurate rates for T staging of rectal carcinoma using MRI conventional sequences,DWI,both DWI and MRI conventional sequences were 74.4%(32/43),86.0%(37/43)and 97.7%(42/43),respectively.Conclusion:DWI combined with MRI conventional sequences could be more accurate for the judgments of T-staging of rectal carcinoma. |
