| Abstract | 「要旨」肺区域Phantomを作成し, 肺血流障害の区域欠損描出能をPlanar像と多断層2次元極座標表示とで比較検討した. 肺区域Phantomにおいて, 多断層2次元極座標表示はPlanar像より区域描出に優れ, とくに両側中下葉で有用と思われた. 臨床例についても比較検討を加えた結果, 多断層2次元極座標表示はPlanar像より区域描出に優れ, とくに両側下葉で有用であった. 肺血流障害の客観的評価の指標としてExtent, Severity Scoreを算出した. 得られた値は肺癌群, 肺結核群との間で統計学的な有意差を認め, それぞれの鑑別の一助になると思われた. |

| Abstract | The initial study reports the characteristic performance using lung segmental phantom filled in Tc-99m-pertechnetate. To evaluate the segmental defect in lung perfusion scintigraphy, we applied Bull's-eye analysis in addition to planar image set. Bull's-eye analysis especially facilitated the interpretation in both middle and lower lobes. Subsequently, to evolute the clinical application of Bull's-eye analysis, pulmonary scintigraphy was performed on 10 normal subjects and 60 patients with several pulmonary diseases. Of interest, Bull's-eye analysis, however, encouraged the interpretation in both lower lobes. To calculate the extention and severity of perfusion defect, the present study describes Bull's-eye analysis. Quantitative scoring showed higher in the patients with lung cancer than in those with pulmonary tuberculosis. The present study focus that Bull's-eye analysis can be useful of evaluation for perfusion in the patients with pulmonary a couple of diseases. |
