摘要:
多模式融合显像已成为临床应用的发展趋势,特别是PET-CT的出现,为临床影像引入了新的观点。事实证明,PET-CT无论在临床诊断还是实验研究中都极具价值,但PET-CT也存在一些不足,主要表现为CT显示软组织的对比度低及对患者会产生一定的辐射剂量,而MRI可以克服CT的这些缺点,其拥有完美的软组织对比度,时间、空间分辨率高,没有辐射危害,MRI本身还可以提供功能信息,因此相信,PET-MRI会在一定程度上替代PET-CT成为多模式肿瘤显像新的发展方向。
Abstract:
Multimodality imaging, specifically PET-CT, brought a new perspective into the fields of clinical imaging. Clinical cases have shown that PET-CT has great value in clinical diagnosis and. experimental reaserch. But PET-CT still bears some limitations. A major drawback is that CT provides only limited soft tissue contrast and exposes the patient to a significant radiation dose. MRI overcome these limitations, i t has excellent soft tissue contrast, high temporal and spatial resolution and no radiation damage. Additionally, since MRI provides also functional information, PET-MRI will show a new direction of multimodality imaging in the future.
