正电子发射断层与计算机断层成像(PET-CT)是当前最先进的代谢性成像技术,能够在很短的时间内获取理想的解剖和功能性融合影像,可更好地定位和评价头颈部恶性肿瘤的颈淋巴结转移及其未知原发灶,有助于提高诊断和分期的准确性。本文就该技术在头颈部恶性肿瘤颈淋巴结转移诊断方面的研究进展进行综述。
Positron emission tomography and computed tomography (PET-CT) are the most advanced metabolic imaging technologies that provide ideal anatomic and functional fusion images in a short period of time for better positioning and evaluation of the head and neck Malignant cervical lymph node metastasis and its unknown primary tumor, help to improve the accuracy of diagnosis and staging. This article reviews the progress of this technique in the diagnosis of cervical lymph node metastases of head and neck malignant tumors.
