摘要 目的探讨磁共振成像(MRI)及磁共振功能成像(fMRI)联合应用在早期前列腺癌诊断中的价值及限度。方法回顾性分析经病理穿刺活检、手术及随访证实的60例早期前列腺癌(PC)患者的常规MRI和MR扩散加权成像(DWI)和MR波谱分析(MRS)资料。判定早期前列腺癌的MRI及fMRI特点。结果1.60例早期前列腺癌患者中,病变均位于包膜内,有51例表现为T2WI外周带内异常低信号区或前列腺带状结构破坏,周围带与中央带界线消失。9例位于中央带,表现为中央带信号不均,可见等或稍高信号结节。2.MRS上53例Cit明显下降,Cho明显升高,7例变化不明显。3.39例病灶在DWI上呈高信号,ADC图呈低信号,12例信号差别不明显,9例外周带信号均匀,中央腺体区信号不均匀。结论MRI和fMRI联合应用在早期前列腺癌诊断中具有特征性表现,具有明确的诊断价值。但对中央腺体早期前列腺癌的诊断仍有一定限度。
