【摘要】 目的探析MRI常规序列联合DWI对结直肠癌病变的诊断意义。方法选取2016年1月至2018年12月我院收治的结直肠癌患者114例,均给予MRI常规序列检查以及MRI常规序列联合DWI检查,并与病理学诊断结果进行比较。结果 MRI常规序列检查T分期:一致100例,不一致14例,其中高估分期10例,低估分期4例。T₀准确率86.96%,T₁准确率91.30%,T₂准确率90.91%,T₃准确率83.33%,T₄准确率86.36%,总体准确率87.72%。MRI常规序列检查N分期:一致96例,不一致18例,其中高估分期4例,低估分期14例。N₀准确率85.21%,N₁准确率85.72%,N_2a准确率83.33%,N_2b准确率82.80%,总体准确率84.21%。MRI常规序列联合DWI检查T分期:一致104例,不一致10例,其中高估分期10例,低估分期0例。T₀准确率91.30%,T₁准确率95.65%,T₂准确率90.91%,T₃准确率87.50%,T₄准确率90.91%,总体准确率91.23%。MRI常规序列联合DWI检查N分期:一致103例,不一致11例,其中高估分期8例,低估分期3例。N₀准确率92.60%,N₁准确率89.35%,N_2a准确率90.01%,N_2b准确率89.74%,总体准确率90.35%。结论 MRI常规序列联合DWI对结直肠癌病变的诊断意义重大,值得肯定。更多还原

【Abstract】 Objective To explore the diagnostic significance of MRI routine sequence combined DWI in colorectal cancer. Methods From January 2016 to December 2018,114 patients with colorectal cancer were selected, MRI routine sequence examination and MRI routine sequence joint DWI examination, and compared with pathological diagnosis results. Result MRI routine sequence examination T staging: 100 cases were consistent, 14 cases were inconsistent, including 10 cases of overestimation and 4 cases of underestimation. The accuracy rates of T₀, T₁, T₂, T₃ and T₄ were 86.96%, 91.30%, 90.91%, 83.33%, 86.36% respectively, and the overall accuracy rate was 87.72%. MRI routine sequence examination N staging: consistent in 96 cases, inconsistent in 18 cases, of which 4 cases were overestimated, 14 cases were underestimated. N₀ accuracy rate 85.21%, N₁ accuracy rate 85.72%, N_2a accuracy rate 83.33%, N_2b accuracy rate 82.80%, the overall accuracy rate is 84.21%. MRI routine sequence combined with DWI in T staging: 104 cases were consistent, 10 cases were inconsistent, including 10 cases of overestimation and 0 case of underestimation. T₀ accuracy rate 91.30%, T₁ accuracy rate 95.65%, T₂ accuracy rate 90.91%, T₃ accuracy rate 87.50%, T₄ accuracy rate 90.91%, the overall accuracy rate is 91.23%. MRI routine sequence combined with DWI in N staging: 103 cases were consistent, 11 cases were inconsistent, including 8 cases of overestimation and 3 cases of underestimation. N₀ accuracy rate 92.60%, N₁ accuracy rate 89.35%, N_2a accuracy rate 90.01%, N_2b accuracy rate 89.74%, overall accuracy rate 90.35%. Conclusion MRI routine sequence combined with DWI is of great significance in the diagnosis of colorectal cancer.更多还原
