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/mm(2) when two lesions in the overdiagnosis group at both b values.
Conclusion:
DWI and the ADC value have potential for evaluating cancer extension.
