INTRODUCTION
Hybrid imaging systems providing morphological and functional data in a single session have been available for oncological imaging for some time. So far, computed tomography (CT) has been the morphological method-of-choice for inclusion into these hybrid imaging systems. However, recently, research has focused on hardware-based fusion of function with magnetic resonance imaging (MRI) rather than CT.
OBJECTIVES
Now that the first head-only positron emission tomography (PET)/MRI systems have been installed and whole-body systems are to be expected in the near future, potential indications in clinical oncology have to be addressed.
DISCUSSION
This article discusses potential indications of PET/MRI in whole-body oncology imaging. Potential advantages and disadvantages compared with currently available hybrid imaging systems will be reviewed.
引言
能够在单次检查中提供形态学和功能数据的混合成像系统已应用于肿瘤成像领域一段时间了。到目前为止，计算机断层扫描（CT）一直是纳入这些混合成像系统的形态学首选方法。然而，最近的研究重点已转向基于硬件的功能与磁共振成像（MRI）融合，而非CT。
目的
鉴于首批仅用于头部的正电子发射断层扫描（PET）/MRI系统已安装，且预计不久后将有全身系统问世，临床肿瘤学中的潜在适应证必须予以探讨。
讨论
本文讨论PET/MRI在全身肿瘤成像中的潜在适应证。将对与现有混合成像系统相比的潜在优缺点进行综述。
