Direct Visualization of FDG Accumulation from Colonic Wall to Lumen on Dual-Time-Point PET

雙時相正子斷層掃描直接呈現FDG累積從腸壁至腸腔之變化

摘要


一位大腸癌患者,由於電腦斷層掃描發現肝臟不明微小病灶,懷疑惡性轉移,進而接受FDG正子斷層掃描。藉助於較長延遲間隔及較久掃描時間的非常規延遲造影方法,肝臟病灶經由病理檢查確診為肝臟轉移。此外,雙時相正子斷層掃描影像顯示FDG累積從腸壁至腸腔之變化。基於此意外發現,我們提出假說以解釋大腸FDG累積的機制。

並列摘要


A 71-year-old female patient with a newly diagnosed colon cancer underwent whole-body FDG PET scan on suspicion of hepatic metastasis due to a small indeterminate lesion on contrast-enhanced CT. The small hepatic lesion was successfully diagnosed by histopathologic examination as liver metastasis under the help of an unconventionally delayed PET approach with more postponed time interval and prolonged emission time. In addition, FDG accumulation from colonic wall to lumen was demonstrated by dual-time-point PET images. Based on our incidental findings, we proposed the hypothesis to explain the mechanism of colonic FDG accumulation.
