Abstract「要旨」骨疾患の検索におけるTc-99m標識リン酸化合物による骨シンチグラフィ, EMI-scanner CT5005/12によるCTスキャン, X線単純写真の有用性を検討した. 対象は, 3検査を施行した132例, 計240病変で, 異常所見の検出率は, 骨シンチグラフィで232/240 (96.7%), CTスキャンで75/111 (67.7%), X線単純写真で122/210 (58.1%) であり, 偽陰性は, 骨シンチグラフィでは骨盤部, 頸胸部, CTスキャンでは横断面のうすい骨, X線単純写真では骨の重なりの多い部位に生じ易かった. また, 転移性骨腫瘍のCT像の分類を試み, 転移性脊椎腫瘍19病変につき, CTスキャンにより求めたCa濃度と, 単純写真および骨シンチグラフィ所見の関係を検討した. CTスキャンは, 単純写真より微少なCa濃度の変化をよく反映したが, Ca濃度と骨シンチグラフィ所見とは必ずしも相関しなかった.

Abstract[Summary] For the detection of skeletal diseases, comparative studies on CT scan with bone scintigraphy and plain X-ray photos were performed in 132 cases and the results were discussed. Bone scintigraphy with Tc-99m phosphorous compounds was performed with PHO/GAMMA HP. 6406 or PHO/GAMMA LFOV, and the findings were classified into positive, equivocal and negative according to the density of lesion in films. EMI-scanner CT 5005/12 was used and Ca concentration was calculated and played back for this study. Plain X-ray photos were taken in P-A and other projections. Total 240 lesions in 132 cases were found by examinations : 232 lesions were by bone scintigraphy, 75 abnormal findings were found in 111 lesions by CT scan and 122 in 210 by X-ray photos. Ninety-two lesions were studied by 3 methods on the same lesions (primary bone tumors were 6, metastatic bone tumors 65 and others 21). Forty-two lesions in 65 metastatic bone tumors (including suspicion) showed abnormal findings by CT scan and the CT images were classified as follows : I. Non-destructive type : Outline of the bone is kept clearly. (23 lesions) a. Hardening type (10 lesions), b. Doughnut type (4 lesions), c. Fleck type (9 lesions) II. Destructive type : Outline of the bone is irregular and partly destructed, sometimes low density in the bone. (19 lesions) Ca concentrations in 19 metastatic vertebral tumors were correlated better by CT scan than by plain X-ray photos. And there was not clear correlation of Ca concentration with the degree of abnormal accumulation in the bone scintigraphy.
