To investigate the feature of normal uterus MRS, and its relationship with menstrual cycle, seven generative healthy female volunteers underwent pelvic MR scan at three different point of their menstrual cycle - premenstrual, post menstrual and ovulatory phase. MRS were acquired and set SNR no less than 2 as the base line of a discernable signal. Choline is the only signal that could be detected in every case, while its peak varies according to different point of a cycle, highest in premenstrual phase. Such change indicates that choline peak is a normal signal of uterus, maybe derived from of endometrium.
