Abstract:
Objective To quantitatively evaluate the metabolic changes of prostate adenocarcinoma using magnetic resonance spectroscopy (MRS).Methods Eighteen patients of prostate cancer proved by ultrasound guided systemic biopsy were enrolled in this study.All the puncture locations were marked and the corresponding (Choline+Creatine)/Citrate ratios were calculated on the basis of the MRS metabolic map.Results 204 samples were obtained and 106 of them were diagnosed as cancer.The average (Cho+Cre)/Cit ratio in the 106 positions was 2.53?1.02.The (Cho+Cre)/Cit ratio of cancer area was statistically higher than that of noncancerous area (F=8.64, P
