Magnetic resonance spectroscopic imaging (1H-MRSI) and dynamic contrast-enhanced magnetic resonance (DCE-MRI): pattern changes from inflammation to prostate cancer.

摘要

PURPOSE: To assess (1)H-magnetic resonance spectroscopic imaging ((1)H-MRSI) and dynamic contrast-enhanced magnetic resonance (DCE-MRI) features in histologically confirmed prostatic chronic inflammation, prostatic intraepithelial neoplasia (PIN), low grade prostate cancer (LGPCa), and high grade prostate cancer (HGPCa). MATERIALS AND METHODS: Ninety-six men were selected, who showed at histology a diagnosis of chronic inflammation (Group B), high grade (HG) PIN (Group C), or prostate cancer (LGPCa = Group D and HGPCa = Group E). RESULTS: ANOVA analysis shows that inflammation (Group B) displays no significantly (p >.05) different choline and citrate levels when compared to HGPIN and LGPCa. CONCLUSION: our results suggest the potential for these MR imaging techniques in the description of inflammatory and proliferative lesions inside the prostate gland.
