tCho concentration and tumor volume were determined using in-vivo MRS and MRI in triple negative (TN), non-triple negative (nTN) and triple positive (TP) breast cancer patients. TN patients were of younger age (28 to 39 yrs) compared to nTN and TP patients. tCho concentration was significantly lower in TN (3.8 1.0 mmol/kg) compared to nTN (4.7 3.1 mmol/kg) and TP (5.4 2.5 mmol/kg) patients while tumor volume was similar in all patients. Reduced choline kinase expression and high degradation of phosphatidylcholine might have led to lower tCho in TN patients; however, this warrants further investigations.
