Abstract 

Aim

To investigate the feasibility of using diffusion-weighted MR imaging (DWI) to accurately measure breast cancer extension.

Materials and Methods

The extensions of 59 breast lesions were investigated on DW images and apparent diffusion coefficient (ADC) maps and compared to the pathological exams.

Results

Three groups were observed: accurate, overdiagnosis, and false negative. There were no significant differences seen in accurate or false-negative group when b was 500 and 1000 s/mm2 when two lesions in the overdiagnosis group at both b values.

Conclusion

DWI and the ADC value have potential for evaluating cancer extension.
