| Abstract | 「要旨」特発性間質性肺炎(5例), サルコイドーシス(3例), リウマトイド肺(1例)および気管支肺炎(1例)などあわせて10例のび漫性肺疾患にGa-67 citrate SPECTを施行した. SPECT imageは, 通常planar imageでは重積してしまう胸椎や胸骨および乳房などの肺外性集積と肺内性集積とを明瞭に区別できるため, planar imageよりも優れていた. 胸椎の集積に対する肺野の集積の比(mean P/V ratio)をもとめると, 正常群では0.5±0.04の範囲にあり, それに対してび漫性肺疾患群では有意に高値を示した(p<0.01). 肺野の集積の程度を肝のそれを基準にして評価する従来の判定法は不確実であることが示唆された. |

| Abstract | Ga-67 citrate single photon emission computed tomography (SPECT) was performed in 10 cases of diffuse pulmonary diseases ; 5 cases of idiopathic interstitial pneumonitis, 3 cases of sarcoidosis (pulmonary type), 1 case of rheumatoid lung and pneumonia. SPECT image was more excellent and accurate than planar image, because SPECT image was able to distinguish abnormal intrapulmonary accumulation from normal extrapulmonary accumulation ; sternum, vertebrae and mammary gland, etc, which were usually overlapping on the planar images. The ratio between intrapulmonary accumulation and vertebral accumulation computed on SPECT images (P/V ratio) was 0.5+-0.04 in normal cases. The P/V ratio was elevated in diffuse pulmonary diseases (p<0.01). |
