摘要:
多模式显像技术PET-CT和SPECT-CT已经成为临床实践和基础生物医学研究常用的检查方法,并且技术日益成熟。但PET-CT作为有效的临床基本检查工具,仍然受到许多限制,为克服这些困难,目前研究的热点集中在PET和MRI融合技术上。PET-MRI是综合了多参数功能成像和高分辨率的显像技术,尤其适用于对软组织要求较高、受照射剂量限制的小动物成像实验研究和人体临床研究,初步的研究结果显示,PET-MRI技术可在多方面优于PET-CT,PET和MRI在临床应用的互补作用将会使分子影像学进一步发展。
Abstract:
Multimodality imaging with PET-CTand SPECT-CT has become commonplace in clinical practice and in preclinical and basic biomedical research.Although PET-CT is already an established clinical tool it still bears some limitations.To overcome these limitations,recent research concentrates on the combination of PET and MRI into one single machine.Combined PET-MRI allows for multi-parametric imaging and reveals one or more functional processes simultaneously along with high-resolution morphology.Especially in small-animal research,where high soft tissue contrast is required,and the scan time as well as radiation dose are critical factors,the combination of PET and MRI would be beneficial compared with PET-CT.
