图像融合技术的产生首先促进了PET-CT仪的出现, 这是医学影像仪器发展史上的一大突破, 先进的检查方式及良好的应用前景使得在国内得以迅速普及, 并相继促成了SPECT-CT及PET-MRI仪的研制。虽然目前PET-MRI仪在全球装机数量甚少, 仪器尚处于进一步成熟阶段, 但由于MRI相对于CT在软组织图像分辨力方面具有明显优势以及临床对分子影像与功能影像的追求[1], 可以预见PET-MRI的普及并不会太迟。本文就PET-MRI图像融合技术的发展及其临床应用研究做一综述, 并期盼更多研究成果能够应用于临床。

摘要: PET-CT的出现和逐渐普及使大家认识到了其对恶性肿瘤的诊断、分期、疗效评价和判断预后等方面的优势,由于MRI的无辐射性及其在软组织分辨率方面的优势,在PET-MRI机型逐渐成熟后将再引发PET-MRI的装机热潮。该文主要就图像融合技术的发展历程以及目前部分学者在PET-MRI临床应用方面的研究做些归纳,以帮助人们了解此新仪器的功用,认识其广泛的应用前景。而在PET-MRI普及之前,仍可依据现有设备进行相关图像融合及临床应用研究。

Abstract: The emerging and growing in popularity of PET-CT scanner brings us the convenience and cognizes the advantages such as diagnosis, staging, curative effect evaluation and prognosis for malignant tumor.And the PET-MRI installing maybe a new upsurge when the machine gradually mature, because of the MRI examination without the radiation exposure and with the higher soft tissue resolution.This paper summarized the developing course of image fusion technology and some researches of clinical application about PET-MRI at present, in order to help people to understand the functions and know its wide application of the upcoming new instrument, mainly focuses the applications on the central nervous system and some soft tissue lesions.And before PET-MRI popularization, people can still carry out some researches of various image fusion and clinical application on the current equipment. -
