ABSTRACT
Objective To investigate the application value of functional magnetic resonance imaging nethods diffusion weighted imagingand dynamic contrast-enhanced magnetic resonance imaging in theT stagingof rectal cancer.Methods Through the retrospectively analysis of DWI and DCE-MRI images of 78 rectal cancer patients confirmed by pathology,the different of routine sequence examination and functional magnetic resonance imaging combined with routine sequence examination in T thestaging diagnosis were contrasted analysis.The correlation of ADC value and quantitative parameters of Ktrans,Kep and Ve values with tumor T staging was analyzed.Results The functional magnetic resonance imaging combined with routine sequence examination in T staging screened 68 cases successfully,and the accuracy rate was 87.2%.preoperative T staging and postoperative pathology of rectal cancerwas better thanroutine sequence examinationin T staging (59 cases,with the accuracy rate 75.6%) (Kappavalue0.81 vs 0.65,P < 0.05).The ADCvalue andDCE-MRI quantitative parameters values of K and Ve increased with the increase of tumor T staging (P < 0.05).There was no statistically significant difference of Kep values.Conclusions The ADC value and DCE-MRI quantitative parameters (K and Ve values) had certain relevance with Tstaging of rectal cancer.The functional magnetic resonance imaging had a high accuracy in the preoperative T staging of rectal cancer,which proves certain clinical value in judging invasion depth of tumor in the rectal wall.
