摘要目的探讨双时间点成像(DTPI)对非小细胞肺癌(NSCLC)治疗前淋巴结(LN)分期的诊断效能。方法这是一项包括47例非小细胞肺癌病人的回顾性研究,病人采用18F-脱氧葡萄糖(FDG)PET行DTPI检查(早期和延迟期)。迭代法重建PET数据(点扩散函数+时间飞越法)。PET检查的
Abstract Objective To investigate the diagnostic efficacy of dual time-point imaging (DTPI) in lymph node (LN) staging of non-small cell lung cancer (NSCLC) before treatment. Method This is a retrospective study of 47 patients with non-small cell lung cancer who underwent DTPI (early and late) with 18F-deoxyglucose (FDG) PET. Iterative method to reconstruct PET data (point spread function + time flight method). PET examination
