摘要
在过去的几十年里,医学成像技术得到了迅速的发展以及广泛的应用。但目前存在的成像技术,如X-CT、PET、SPECT、MRI、超声以及光学成像等,没有一种成像方式能适用于所有方面的临床应用。不同成像技术各有所长,互相补充,这为多模式成像技术的发展提供了契机。首先介绍了多模式成像的历史和现状,然后介绍了PET/CT、SPECT/ET以及PET/MRI等系统的发展情况、技术细节以及临床应用,最后讨论了多模式成像过程中需要注意的问题,并展望了多模式成像技术的前景。
Over the past several decades, medical imaging technology has developed rapidly and got wide applications. However, there is no one single imaging model suitable for all the clinical applications in the existing imaging technologies, such as X-CT, PET, SPECT, MRI, ultrasound, optical imaging and so on. Each one of them has its advantage and they can complement others, which brings on the development of the multi-modal imaging technology. This review gives introduction of the development of multi-modal imaging technology. Then, developments of systems, details of techniques and clinical applications are introduced in different terms including PET/CT, SPECT/CT, PET/MRI and so on. In the end, issues which should be considered, as well as the prospect of multi-modal imaging technology, are discussed.
