2-Deoxy-2-[18F]fluoro-D-Glucose positron emission tomography (FDG-PET) stages patients with Hodgkin's disease (HD) and Non-Hodgkin's lymphoma (NHL) with higher accuracy than computed tomography (CT). We sought to determine whether integrated (hardware) fused PET/CT imaging results in further improvements in staging accuracy.
Seventy-three patients (age 51 +/- 17 years, 37 female, 36 male) with HD (n = 20) or NHL (n = 53) undergoing staging were studied with an integrated PET/CT system. Image findings were verified by clinical follow up, additional imaging and when available, histology.
Thirty-four of 73 patients (46.5%) had evidence of disease and 39 were disease free as confirmed by clinical evaluation and follow-up for 41 +/- 22 weeks (n = 73), including biopsy (n = 26), and other imaging modalities (n = 52) when available. A discordant image interpretation between PET and PET/CT occurred in seven patients (10%). PET/CT correctly upstaged two and downstaged five patients. Overall staging was accurate in 93% with PET/CT and 84% with PET (P = 0.03).
Lymphoma is staged with higher accuracy using PET/CT than PET alone.
2-脱氧-2-[18F]氟-D-葡萄糖正电子发射断层扫描(FDG-PET)对霍奇金病(HD)和非霍奇金淋巴瘤(NHL)患者进行分期的准确性高于计算机断层扫描(CT)。我们试图确定一体化(硬件)融合PET/CT成像是否能进一步提高分期准确性。
使用一体化PET/CT系统对73例接受分期检查的HD患者(n = 20)或NHL患者(n = 53)进行研究(年龄51±17岁,女性37例,男性36例)。通过临床随访、额外的影像学检查以及(如有)组织学检查来验证图像结果。
73例患者中有34例(46.5%)有疾病证据,39例无疾病,经41±22周(n = 73)的临床评估和随访证实,包括活检(n = 26)以及(如有)其他影像学检查(n = 52)。7例患者(10%)PET与PET/CT的图像解读不一致。PET/CT正确地将2例患者分期上调,5例患者分期下调。PET/CT总体分期准确率为93%,PET为84%(P = 0.03)。
使用PET/CT对淋巴瘤进行分期的准确性高于单独使用PET。
