High choline-containing metabolite (tCho) differentiates malignant breast tissues from benign lesions. However, tCho is also seen in normal and in lactating breast tissues and hence there is need for determination of absolute tCho concentration. Early breast cancer patients had significantly higher tCho concentration compared to locally advanced breast cancer patients. The cut-off values of tCho concentration obtained gave clear differentiation between early, locally advanced breast cancer, benign lesions and normal breast tissues. The results help in the progress of breast proton MRS from the stage of investigational research to the role that could be efficaciously used in routine clinical practice.
