| Abstract | 「要旨」今回, われわれは椎体部の病変に関して核磁気共鳴装置（以下NMR）と骨シンチグラフィの異常所見の意義について比較検討した. 対象は, 悪性腫瘍骨転移症例10例, 第3腰椎のGranular cell carcinoma 1例, および頸椎カリエス1例の計12例である. NMRと骨シンチグラフィの一致症例は5例, 不一致症例は7例であった. NMRと骨シンチグラフィの不一致症例のうち骨シンチグラフィで異常を認め, NMRで異常を認めなかった3例は微細な骨浸潤に対するNMRの低感受性に起因すると思われる. NMRで異常を認め, 骨シンチグラフィで異常を認めなかった4例中3例は腫瘍の治療が行われたあとの症例で, 治療前の骨シンチグラフィではNMRと同部位に異常を認めており, NMRが非可逆的な骨髄内の脂肪髄の減少をとらえたものと考えられる. また残る1例は骨シンチグラフィの低空間分解能のためと考えられる. このように, 椎体部病変に関して, NMRと骨シンチグラフィでは異なる現象をとらえており, 病態の把握に対し両者は相補的な関係にあると考えられる. |

| Abstract | [Summary] A comparative study of NMR and bone scintigraphy was performed in vertebral disorders, and the significance of both modalities was evaluated. Twelve patients with various vertebral abnormalities including ten cases of vertebral metastases, one case of cervical caries and one case of Granular cell tumor of L3, were examined. In 4 patients, NMR showed abnormalities in the same regions as the bone scintigrams. In another 3 patients. NMR did not show the disorders reported on bone scintigrams. This may be due to the low NMR sensitivity to tiny infiltration of tumor cells in the bone marrow. In 3 out of the remaining 5 patients, NMR demonstrated abnormal findings, whilst the bone scintigrams were normal. Previous bone scintigrams in these patients before treatment had shown abnormal accumulation of activity in the region of abnormal NMR findings. This may be due to the fact that NMR detects the irreversible change of bone marrow, and bone scintigram demonstrates the turn over of bone minerals. This limited experience suggests that both madalities are complementary in the evaluation of vertebral abnormalities. |
