Abstract「要旨」 運動負荷タリウム像の判定に男女の差を考慮すべきか否かを検討するため, 臨床上正常と考えられた36例(男性18例, 女性18例)のタリウム二次元像からcircumferential profile曲線を用いて心筋内タリウム分布を定量評価した. 運動負荷時間は男性(14±3分)に比べ, 女性(11±3分)で短かったが(P<0.01), 最大心拍数, 収縮期血圧, 肺/心筋カウント比には差はなかった. 負荷時の平均曲線は, 女性で前壁および上部中隔の分布の低下を示し, 特に左側面像での前壁では, 男性に比べ10%以上低下していた. 3時間後のタリウムの洗い出しは男性(43±7%)に対し, 女性(48±8%)で高かったが(P<0.01), 特に前面像で差が明らかであった. タリウムの分布は, 胸壁や乳腺による吸収の影響を受けやすく, 日本人においても性差を十分考慮して読影する必要があると考えられる.

Abstract[Summary] To determine the sex differences in the tracer distribution on stress thallium-201 imaging, the studies of 18 normal males and 18 normal females were subjected to quantitative circumferential profile analysis in each projection image. Although the exercise duration was shorter in females(11+-3 min) than in males(14+-3 min)(p<0.01), the peak heart rate, peak systolic pressure and the lung-to-myocardial count ratio were similar between them. The averaged profile curves in female showed a significant reduction in tracer uptake in anterior and upper septal regions, particularly in the study of lateral view, which may be attributed to breast attenuation. In addition, the percent washout of thallium in 3 hours was higher in females(48+-8%) than in males(43+-7%)(p<0.01), particularly in the study of anterior view. We conclude that important differences in the pattern of thallium uptake and washout between males and females should be considered for interpretation of stress thallium imaging.
