双能CT对甲状腺结节诊断价值的研究进展

Research progress of dual-energy CT in the diagnosis of thyroid nodules

随着临床诊断技术的发展及体检的普及,甲状腺结节的检出率逐年增加,已成为目前最常见的甲状腺病变之一,无创的影像学检查对其术前诊断有重要作用。双能CT即利用两种不同能谱的X射线能量进行成像,可为甲状腺结节的诊断提供多种不同参数的图像,是常规CT的重要补充。本文对双能CT的基本原理、多参数成像进行了总结,同时对双能CT在甲状腺结节的诊断、鉴别诊断及评估患者是否存在淋巴结转移的价值以及双能CT的其他潜在应用价值的研究现状进行综述,为未来双能CT在甲状腺结节诊断的相关临床应用及研究提供了思路。

Thyroid nodules are now among the most frequent thyroid lesions,with a yearly rise in detection rates due to advancements in clinical diagnostic procedures and the widespread use of physical examinations.A non-invasive imaging assessment is crucial to the preoperative diagnosis of this condition.Dual-energy CT is a valuable addition to standard CT because it uses X-ray radiation from two distinct energy spectrums to offer a range of pictures with varied characteristics for the identification of thyroid nodules.This study provides an overview of dual-energy CT's multi-parameter imaging and basic principles.In order to generate ideas for the clinical application and future research of dual-energy CT in the diagnosis of thyroid nodules,the value of dual-energy CT in the diagnosis,differential diagnosis,and evaluation of lymph node metastasis in patients with thyroid nodules,as well as other potential application values,are reviewed concurrently.
