摘要
因MRI具有良好的软组织分辨率、多方位成像、多参数功能成像等优点,逐渐成为运用影像学诊断前列腺癌的重要检查方法。随着MRI成像技术的不断成熟,多种成像方法如磁共振灌注成像(perfusion weighted imaging,PWI)、扩散加权成像(diffusionweightedimaging,DWI)、体素内不相干运动(intravoxel incoherent motion,IVIM)扩散成像、磁共振波谱成像(magnetic resonance spectroscopy,MRS)、扩散张量成像(diffusion tensor imaging,DTI)、扩散峰度成像(diffusion kurtosis imaging,DKI)、T2 mapping技术、磁敏感加权成像(susceptibility weighted imaging,SWI)在前列腺癌的诊断中有着重要的作用,随着这些技术的发展,前列腺癌诊断的准确性明显提高,现将近年来磁共振成像技术在前列腺癌诊断中的作用展开综述。
Because magnetic resonance imaging(MRI)has the advantages of good soft tissue resolution,multi-directional imaging and multi-parameter functional imaging,it has gradually become an important imaging method for the diagnosis of prostate cancer.With the maturity of MRI imaging technology,a variety of imaging methods such as magnetic resonance perfusion imaging(PWI),diffusion-weighted imaging(DWI),intravoxel irrelevant motion(IVIM)diffusion imaging,magnetic resonance spectroscopy(MRS),diffusion tensor imaging(DTI),diffusion kurtosis imaging(DKI),T2 mapping and magnetic susceptibility weighted imaging(SWI)play an important role in the diagnosis of prostate cancer.With the development of these technologies,the accuracy of prostate cancer diagnosis has been significantly improved.The role of magnetic resonance imaging in the diagnosis of prostate cancer in recent years is reviewed.
