Apparent diffusion coefficient (ADC) was calculated using diffusion weighted imaging in 72 invasive ductal carcinoma patients at 1.5T with known HER2, ER and PR status. Mean ADC in HER2+, ER+ and PR + were not significantly different compared to HER2-, ER- and PR- patients. Age of ER+ (4911.3years) patients was statistically significant compared to ER- (4311.3years). Measured ADC was not significant but showed variation (0.7-1.4x10-3 mm2/s) with the different tumor sub types which might be attributed to intratumor and intertumor heterogeneous nature of breast lesions or other molecular features of breast cancer which is influenced by genomic variation, etc,.
