正电子发射体层摄影(PET)是一种反映机体功能代谢变化的核医学影像诊断技术,其最突出的优势是在肿瘤诊断,目前世界各地约70%的PET用于肿瘤患者,而国内基本上全用于肿瘤患者,如肺癌、乳腺癌、头颈鳞癌、结直肠癌、恶性黑色素瘤、恶性淋巴瘤等。本文对PET检查在头颈部恶性肿瘤中的应用进展综述如下。1 PET基本原理PET是一种全身功能成像,是利用核素示踪原理显示活体生物代谢活动的核医学影像技术。目前临床
Positron emission tomography (PET) is a nuclear medicine diagnostic imaging technology that reflects the functional and metabolic changes of the body. The most prominent advantage of PET is the diagnosis of tumors. About 70% of the PET in the world is currently used in cancer patients. However, On the whole for cancer patients, such as lung cancer, breast cancer, head and neck squamous cell carcinoma, colorectal cancer, malignant melanoma, malignant lymphoma. This article reviews the progress of PET in the treatment of head and neck cancer. 1 PET Fundamentals PET is a functional imaging of the body is the use of nuclear nuclide tracer principle of biological activity of nuclear medicine imaging technology. Currently clinically
