| Abstract | 「要旨」 81mKr持続静注法と99mTc-MAAによる血流分布の差から, 単位肺容量当たりの換気量 (V/V (R) Q) を求めた. そして, 81mKr吸入法による換気分布と133Xe反復呼吸時の肺容量分布から求めたV/V (R) Vと比較し, V/V (R) QがV/Vを表わしていることを, 臨床例において実証した. 検査は坐位安静呼吸下に行った. 肺野を重力方向に6mm厚のスライスに分画し, 各スライスにおいてV/V (R) QとV/V (R) Vを求め, 両者の相関を求めた. 10例 (20肺) における相関係数は1例を除いて0.76〜0.95と高かった. これらの結果は, 81mKr溶液と99mTc-MAA静注法より求めたV/V (R) Qが, 局所のV/Vを表わしていると考えられる. 本法は, 133Xeを使わずに, V/Vが求められるという利点をもっている. |

| Abstract | [Summary] Distribution of ventilation per unit lung volume (V/V) was measured by intravenous injection of Kr-81m and Tc-99m-MAA on 10 subjects having various pulmonary diseases. The distribution of V/V (R) Q obtained by this method was compared with that (V/V (R) V) obtained by the inhalation method of Kr-81m (V) and Xe-133 gas (V) . The study was performed in sitting position. Kr-81m solution and Tc-99m-MAA was injected continuously to the antecubital vein during tidal breathing. V and V on inhalation study was measured with Kr-81m gas and Xe-133 gas respectively. The lung field was divided in about 30 slices with 6 mm thickness from top to bottom. Relative distribution of V/V was compared between V/V (R) Q and V/V (R) V for each subject. Correlation coefficient was 0.76-0.95 in 20 lungs of ten subjects, except for one lung. This result suggests that the distribution of V/V measured by Kr-81m and Tc-99m-MAA represents regional V/V in the lung. This method is useful to measure V/V when Xe-133 is not available. |
