| Abstract | 「要旨」67Ga-citrateによる腫瘍シンチグラフィーにおいて, 正常眼窩への生理的集積, および片側性眼窩ないし眼球内腫瘍に対する診断的価値に関して検討した. 196例の正常眼窩における検討では, 50歳代までの両側眼窩陽性率は90%近いが, 60歳代を越えると著しく低下し, また, 女性での陽性率が92%であったのに対し男性のそれは62%と明らかに低く, 若年者および女性にて集積の程度, 陽性率共に高いことが示された. 片側性眼窩腫瘤例の陽性率は, 悪性腫瘍80% (4/5) , 良性腫瘍80% (4/5) および炎症性腫瘤78% (7/9) で, いずれも高率であったが, 眼球内悪性腫瘍では, 25% (1/4) しか陽性を呈しなかった. 腫瘤径と陽性率に関する検討では, 15mm以上のものでは93% (14/15) が陽性であったが, 15mm以下では20% (1/5) にすぎず, これらより眼窩および眼球内腫瘍の陽性率は, 病変の種類によるものではなく, 腫瘤径により決定されるものと思われた. |

| Abstract | [Summary] The orbital accumulation of 67Ga-citrate was studied in 196 patients without ophthalmic disease and in 23 patients with unilateral ophthalmic tumorous lesions. In 196 patients without ophthalmic abnormality, symmetric orbital uptake of 67Ga-citrate was higher in female than male and in younger than older. The positive rate for female and male was 92% and 62%, respectively. Six cases showed asymmetric uptake, giving false positive rate of 3%. In a series of 19 patients with unilateral orbital mass, 4 of 5 cases with malignant tumors (80%) , 4 of 5 cases with benign neoplasms (80%) and 7 of 9 cases with inflammatory diseases (78%) revealed positive scintigrams. There were no significant difference among these positive rates. In 4 cases with unilateral occular malignant tumors, only one (25%) showed positive finding. Of the 15 cases of orbital masses with diameter more than 15mm, 14 cases (93%) revealed positive findings. On the contrary, only one of the 5 patients with ophthalmic masses with diameters less than 15mm (20%) showed positive scintigram. We concluded that the positive findings of ophthalmic masses with 67Ga-citrate depended on the size of tumor but not on the pathology of the diseases. |
