| 中文摘要 | 正子斷層掃描(positron emission tomography, PET)已成為臨床上重要影像診斷工具,PET和電腦斷層(computed tomography, CT)影像結合,可提供病灶精確的形態結構,也了解人體細胞組織的生理、病理變化和代謝的改變。在頭頸部癌方面,PET/CT融合影像(fusion image)是否正確成為重要的一環。一位受檢者右側口底有一病灶在第一次影像上似乎有侵犯到下頷骨(mandibular bone)。腦部融合橫狀面得知,PET腦部影像有偏移,延遲相(delay view)顯示此病灶並無侵犯下頷骨。另一受檢者左下齒槽脊(alveolar ridge)病灶在CT影像上有些許偏移,頭部並無移動,但PET掃描時嘴巴張開,導致下頷骨融合影像不符合病灶解剖位置。結論,檢查前告知受檢者掃描時不可移動頭部和身體,造影擺位時,應把固定用具架好或是綁好,使受檢者移動或晃動機率降到最低,以提供正確融合影像診斷判讀。 |
| 英文摘要 | PET has become an important image diagnostic tool since the fusion of both PET and CT images provides not only the accurate morphological structure of lesions, but also information of physiological, pathological and metabolic changes. PET/CT fusion image shows it's importance in the head and neck cancer particularly. In one of our patient with right mouth floor cancer, the first image seems to be mandibular bone involved. However, in the brain transverse fusion image, PET image seems to be shifted, and the delay view confirmed no involvement of mandibular bone. In the other patient, the CT image shows shift of the lesion at alveolar ridge when the head was fixed well during the scan. However, patient's mouth kept open during the PET scan, which caused the mismatch of the fusion image of mandibular bone. In order to provide an accurate fusion image, before examination, not only patient should be informed not to make any movement of head and body during the scan, but also when check the position, technicians should fixed to head holder avoid any movement of patients. |
