| Abstract | 「要旨」体表面心エコー図検査で左房拡大を認める19例に, 99mTc tetrofosmin (Tf) 心筋イメージングを施行し, 心房へのTfの集積の有無と程度を視覚的に評価した. また左房心筋のROIの平均最大カウント(LA)と, 左室心筋のROIの平均最大カウント(LV)の比(LA/LV)を求めて, 心エコー図検査より得られた左心房に関する諸指標との関連を検討した. プラナー像では, 12例で左房描出が可能であった. LA/LVは, 体表面および経食道心エコー図検査で得られた左房面積と正相関を認めた(おのおのr=0.88, 0.91). 開心術後や胸郭の変形のために体表面心エコー図検査で左房の描出困難な例や, 経食道心エコー図検査が施行できない例では, Tf SPECT は左房負荷の評価法として有用である. |

| Abstract | This study was performed to clarify the possibility of visualization and quantification with 99mTc-tetrofosmin (Tf) myocardial scintigraphy in cases with a large atrium demonstrated by trans-thoracic echocardiography (TTE). Myocardial SPECT was evaluated in 4 patients with mitral stenosis and 15 patients with mitral regurgitation. Left atrium was identified in 12 out of 19 cases from an antero-posterior projection. The Tf uptake ratio of the left atrium, which was defined as the ratio of ROI count of the left atrium divided by the ROI count of the left ventricle, showed a good correlation with the left atrial area obtained by both trans-thoracic and trans-esophageal echocardiography (r = 0.88 and 0.91, respectively). These data suggest that Tf myocardial SPECT is a useful method of evaluating left atrial enlargement. |
