The
choline concentration and tumor volume were determined using in-vivo MRS and
MRI in 53 invasive ductal carcinoma patients at 1.5 T with known HER2/neu
status. The tCho concentration for HER2/neu positive cases was 4.8 3.3
mmol/kg which was statistically significantly higher compared to HER2/neu
negative cases (2.7 0.7 mmol/kg; p=0.007). However, the tumor volume for
the Her2/neu positive cases (47.956.1) and negative cases (45.648.3) were
similar (p=0.84). The increase in tCho concentration observed in Her2/neu
positive patients may be attributed to the high proliferative activity of the
Her2neu positive tumors.
