中文摘要 | 目的:硬化性血管瘤是少見的肺部腫瘤,其原發於肺實質內的肺泡型 II 細胞。本研究目 的為探討硬化性血管瘤在雙相正子電腦斷層掃描的表現。 材料和方法:本研究總共收集四位接受雙相正子電腦斷層掃描後證實患有肺硬化性血管 瘤之病人。早期正子造影及延遲正子造影分別於注射氟-18-去氧葡萄糖(FDG)後 60 分鐘 及 180 分鐘進行。我們進一步計算腫瘤之早期 FDG 最大攝取值(SUVmax),延遲 FDG 最大 攝取值(SUVmax),兩次造影之 SUV 變化率(ΔSUVmax)。結果:肺硬化性血管瘤之早期 SUVmax 範圍從 1.0 至 5.1,延遲 SUVmax 範圍從 1.0 至 4.8。 一個血管瘤於延遲造影時呈現 SUVmax 升高,兩個血管瘤於延遲造影時呈現 SUVmax 降 低,其餘一個無明顯之 SUVmax 變化。 結論:本研究發現肺硬化性血管瘤於早期造影呈現低至中度 FDG 攝取增加情形。肺硬化 性血管瘤於延遲造影呈現 SUVmax降低或無明顯變化之情況。雙相正子電腦斷層掃描可能 有效鑑別此血管瘤之良性特質。 |
英文摘要 | Background: Sclerosing hemangioma of the lung is a rare neoplasm deriving from pneumocyte type II cells. The objective of this study is to describe the characteristics of pulmonary sclerosing hemangioma on dual-time point FDG PET-CT scan. Methods: We reviewed dual-time point FDG PET-CT scans of 4 patients with proven pulmonary sclerosing hemangioma. Early and delayed FDG PET-CT scans were performed at one and three hours after intravenous injection of FDG. The SUVmax of early and delayed scans and the percent change in SUVmax between the two time points were measured. Results: Early SUVmax of these tumors ranged from 1.0 to 5.1, and delayed SUVmax ranged from 1.0 to 4.8. One tumor showed increased SUVmax on delayed study, 2 tumors showed decreased SUVmax while the remaining tumor showed no change in SUVmax. Conclusions: Pulmonary sclerosing hemangioma shows low to moderate FDG uptake on early PET-CT scan, and minimal change to even lower SUVmax on delayed study. Dual-time point FDG PET-CT may be useful in characterizing the benign nature of these lesions. |
