| Abstract | 「要旨」: 99mTc-DTPA腎動態シンチグラフィにて大動脈疾患 (閉塞性動脈硬化症, 胸部および腹部大動脈瘤, 解離性大動脈瘤) における腎動脈侵襲の診断がどの程度可能かについて検討した. 腎動脈侵襲の評価の指標として, 初期腎血流イメージでの視覚による判定 (BPI) とコンピュータを用いて算出した相対的分腎機能比 (RSRF) を用いた. 前記疾患45例中, 動脈造影所見と比較し得た24症例 (26スキャン) において, 片腎性動脈病変に関しては, BPIはfalse negative例がなく, そのsensitivityは100% (9/9) , specificityは77% (10/13) で, RSRFはfalse negative例があり, そのsensitivityは78% (7/9) , specificityは92% (12/13) で, 病側の診断に腎動態シンチグラフィは有用である結果を得た. しかし, 両側腎動脈侵襲を有する場合の診断は困難であった. 腎動態シンチグラフィは腎血管病変に伴う二次的な相対的腎血流分布ならびに分腎機能の評価に対して有効な検査法である. |

| Abstract | [Summary] : Dynamic renal scintigraphy has been reviewed for evaluation of renal arterial involvement in aortic disorders such as arteriosclerosis obliterans, abdominal aortic aneurysm and dissecting aneurysm. As a diagnostic finding and parameters, we used blood perfusion images of both kidneys and relative split renal function index obtained with analysis of the time-activity curves which were generated using a renal region of interest. In the diagnosis of unilateral renal arterial involvement, sensitivity and specificity of blood perfusion images were 100% (9/9) and 77% (10/13) and those of relative split renal function index were 78% (7/9) and 92%(12/13) , respectively. Dynamic renal scintigraphy was useful for evaluating unilateral renal arterial involvement in aortic diseases. However, scintigraphic diagnosis of bilateral renal arterial involvement were difficult. And in a severe case, we could not differentiate renal parenchymal damage due to renovascular involvement from senile renal dysfunction or hypertensive renal disease which is often a cause of aortic disorders. |
