摘要
肺癌是严重危害人类生命与健康较为常见的恶性肿瘤之一,其发生率和病死率均占恶性肿瘤的首位,亦是肿瘤致死的首要原因。如何对肺癌进行早期诊断、准确分期、合理治疗,以及改善患者预后,是多年来医学工作的重点,而影像学检查是诊断肺癌的主要手段。随着影像学进展,CT、CT造影、MRI、PET及PET-CT等先进技术的应用,对早期发现肺癌早期诊断起着越来越大的作用,对影像学的肿瘤分期也越来越接近病理。近年来的研究证明,PET是评价肺癌患者有效的非侵入性检查方法之一,但PET对病灶的精确定位有一定限制。PET-CT实现了CT解剖结构与PET功能信息的同机图像融合,可以对病灶进行精确定位。本文主要综述PET-CT对肺癌诊断的应用价值。
Lung cancer is one of the most common malignancies that are life-treatening to human beings. It ranks the first both in morbidity and mortality of malignant tumors. Early diagnosis, accurate staging, proper treatment and improvement of prognosis are the focuses of related studies in recent years. Imaging diagnosis is the main method for diagnosis of lung cancer. The development of imaging diagnosis and the application of advanced techniques such as CT scan, low-dose helical CT scan, MRI, PET and PET-CT , play a great role in early diagnosis and staging of lung cancer. Recent researches have demonstrated that ET is one of the most efficient non-invasive methods for diagnosis of lung cancers. However, PET has limitation in precise location of the focus. PET-CT integrates the functions of CT and PET together, and is able to locate the focus precisely. This article mainly reviews the value of PET-CT in the diagnosis of lung cancer.
