| Abstract | 「要旨」運動負荷タリウム心筋シンチグラフィーの定量評価法として, GorisらのInterpolative Background Subtraction法にて, Backgroundを処理した後, 14点Smoothingを行い, 正常カウントレベルを求めた. 対象は正常人13名(平均年齢45歳)であった. エルゴメータによる多段階負荷法を用いて, 最大負荷の時点でタリウムを4 mCi静注し, 心筋イメージを3方向(AP, LAO 45°, L-LATERAL)より採取した. 心筋イメージに対して, 上記方法にてSubtractionとSmoothingを行い, 8領域に分割して正常カウントレベルを検討した. 後壁は, 14段階表示の上位より5段階目(64〜71%), その他の領域は上位より4段階目(72〜79%)に含まれた. 本法により, 肝脾の重なりを取り除いた心筋イメージを用いて, 視覚的な定量評価が可能であった. |

| Abstract | For a quantitative diagnosis of stress Thallium-201 myocardial scintigraphy, we used the interpolative background subtraction method(Goris's Method)and the 14 point smoothing in 13 normal persons. The multiple stage exercise in ergometer was performed. The endpoint of the stress was symptom-limited or predicted submaximal heart rate. We analyzed quantitatively the myocardial thallium uptake counts after exercise by using minicomputer. Myocardial images obtained in 3 projection(AP, LAO45°, L-LATERAL)were divided into 8 segments. The normal count level was evaluated by the 14 stages(every 7% per one stage, from 0% to 100%). Each segment, except posterior segment, was the fourth stage(72-79%). Only posterior segment was the fifth stage(64-71%). This method eliminated the overlapping of Liver and Spleen activities to Myocardial activity and was very effective for the visually quantitative myocardial analysis. |
