Abstract | 「要旨」神経芽細胞腫の病期分類のために有用な123I-Metaiodobenzylguanidine(以下MIBG)シンチグラフィの撮像方法について検討した. 小児神経芽細胞腫19症例の加療前に123I-MIBGシンチグラフィを施行した. シンチグラムは静注6時間後と24時間後にそれぞれ全身像と, 躯幹部planar像, SPECT像を撮像し, 集積を視覚的に評価し, CT, MRIや, 骨シンチグラフィの所見と比較した. 原発巣には全例でMIBGの集積が認められ, リンパ節転移巣は9例中, 顕微鏡的転移巣であった1例を除いた8例で集積を確認できた. 原発巣, リンパ節転移の広がりを正確に評価するためには24時間後のSPECTが最も優れていた. 骨, 骨髄の転移巣に関しては123I-MIBGの6時間像にて24時間像よりも多数の病変が検出され, MIBGは骨シンチよりも多数で広範囲の異常集積を呈した. 神経芽細胞腫のより多数の病変を検出するために, 123I-MIBGシンチグラフィは, 静注後6時間前後の比較的早期の全身像と24時間前後の後期の躯幹部SPECTを撮像することが有用であると考えられた. |

Abstract | Nineteen children with neuroblastoma (aged 2w.-7y.o.) were studied to evaluate the optimal scan conditions for Iodine-123-Metaiodobenzylguanidine (MIBG) scintigraphy for accurate staging at the time of diagnosis. Six and 24 hours after an injection of 123I-MIBG, whole body image and truncal spot and SPECT images were obtained. Compared with other studies (CT or MRI and bone scintigraphy), each 123I-MIBG image was evaluated visually to investigate which image can demonstrate the extent of neuroblastoma most exactly. MIBG images demonstrated primary tumors in all patients, and metastatic lymphadenopathy in 8 of 9 patients. Twenty-four hour SPECT images gave us the most detailed information about the extent of abnormal accumulation. As to bone and bone marrow lesions, 6 hour images were superior to 24 hour images in detectability. Moreover, MIBG showed many more lesions and more extended accumulation than the hone scan. 123I-MIBG scintigraphy was very useful in detecting neuroblastomas. In order to get the most valuable information, both delayed SPECT and early whole body planar images should he obtained. |
