Abstract
Purpose
To assess the ability of diffusion-weighted imaging (DWI) for evaluating T stage and
correlation with histological T stage of rectal cancer.
Method
The diagnostic accuracy, sensitivity, and specificity of T2WI and DWI combined with T2WI for T stage were evaluated. Mean tumor apparent diffusion coefficient (ADC) was
compared with histological T stage.
Result
There were no significant differences in the diagnostic accuracy, sensitivity, and
specificity no matter what kind of T stage was concerned. The difference between ADC
values and histological T stage were significantly different.
Conclusion
DWI was useful for evaluating T stage of rectal cancer. The ADC may predict the histological
grade.
