【摘要】 与影像学方法比较,利用正电子成像和正电子成像/计算机成像,能更准确地检测到妇科肿瘤。2-[18F]氟-2-脱氧葡萄糖正电子成像用于鉴别淋巴结的良恶性、测量治疗后残留灶或复发灶的大小。在放疗计划制订中,正电子成像/计算机成像提供了更多的诊断信息,指导组织活检。本文就正电子成像和正电子成像/计算机成像在妇科肿瘤诊断、分期、复发、评价治疗效果和预后判断等方面的应用做一综述。更多还原

【Abstract】 The advent of positron emission tomography (PET) and PET/computed tomography (CT) now enables us to detect metabolically active gynecologic cancers with greater accuracy.Fuorine-18 fluorodeoxyglucose PET has been used in differentiation of malignant from benign lymph nodes and residual or recurrent cancers from post-treatment changes.PET/CT supply additional information for the diagnosis and tissue biopsy as well as radiotherapy planning.This paper reviewed the principle and clinical utility of PET and PET/CT in the diagnosis,staging,recurrence,therapeutic response as well as prognosis of gynecologic cancers.更多还原
