P a indicates the comparison of ADC measurements between RS‐EPI and SS‐EPI and P b indicates the comparison of ADC measurements for tumors with different receptor statuses. RS‐EPI and SS‐EPI indicate the ADC measurements of the RS‐EPI and SS‐EPI sequences, respectively.
Bold values indicate statistically significant in P values.
ER = estrogen receptor; PR = progesterone receptor; HER‐2 = human epidermal growth factor receptor‐2.
