The value of MR diffusion-weighted imaging (DWI) in monitoring the response to treatment in cervical cancers

The value of MR diffusion-weighted imaging (DWI) in monitoring the response to treatment in cervical cancers

DWI shows that there is an increase in tumour's diffusivity (the ADC value before radiotherapy was 603 μm2/sec, and the ADC value after radiotherapy is 917 μm2/sec) and a decrease in tumour's volume after the radiotherapy. These changes in tumour's microarchitecture are not initially seen using conventional anatomical imaging.
