正电子发射型计算机断层显像(PET)是一种功能性影像技术,目前已广泛应用于恶性肿瘤的诊断中。PET-CT实现了PET和CT的两种技术的优势互补,使其在头颈部肿瘤放疗中的临床应用已受到越来越多的关注,但对临床的指导意义目前仍存在争议。本文分析了PET-CT在头颈部肿瘤放疗中的应用,包括肿瘤分期,预测放射治疗敏感性及预后,制定放疗计划,评估疗效并监测肿瘤复发等。
Positron emission computed tomography (PET) is a functional imaging technology that has been widely used in the diagnosis of malignant tumors. PET-CT achieves the complementary advantages of the two technologies of PET and CT, and it has received more and more attention in the clinical application of radiotherapy for head and neck cancer. However, there is still controversy about the clinical significance of guidance. This article analyzes the application of PET-CT in radiotherapy for head and neck tumors, including tumor staging, predicting radiotherapy sensitivity and prognosis, establishing radiotherapy plans, assessing efficacy, and monitoring tumor recurrence.
