| Abstract | 「要旨」心疾患22症例の心機能を, 心電図同期99mTc-tetrofosmin SPECT(Gated SPECT)データからQuantitative Gated SPECT(QGS)を用いて解析した. この新しい核医学手法による成績を左室造影および心臓超音波所見と対比した. 左室の拡張末期および収縮末期容積は左室造影のそれと相関し(r=0.78, 0.77), 算出した左室駆出率も相関した(r=0.67). 同解析法のシネモード表示を用い, 左室短軸SPECT像を16分割し, normal, hypokinesis, akinesisの3段階のscoringを行い, 左室壁運動をwall motion score(WMS)として評価して心臓超音波の成績と比較した. 相互のWMSは良好な相関を示した(r=0.85). Gated SPECTデータをQGSで解析することにより, 血流情報と心機能を同時かつ簡便に評価することができる. |

| Abstract | The quantitative gated SPECT (QGS) software that has automatic edge detection algorithm of the left ventricle, is able to calculate LV volumes and visualize LV wall motion with perfusion throughout the cardiac cycle. We evaluated the reliability of global and regional LV function derived from QGS using 99mTc-tetrofosmin by comparing with left ventricular cineangiography (LVG) and echocardiography (ECHO). In 22 cardiac patients, end-diastolic volume (EDV), end-systolic volume (ESV) and ejection fraction (LVEF) were calculated. Using cinematic display, regional LV wall motion were scored on a 3-point scale (1=normal, 2=hypokinesis, 3=akinesis; WMS). EDV, ESV and LVEF correlated well with those by LVG (p<0.001 for each). Correlation between WMS derived from QGS and ECHO was high (r=0.85. p<0.001). There was an inverse correlation between WMS and LVEF (r=0.77, p<0.001). In conclusion, QGS is useful to evaluate global LV function. Regional wall motion evaluated by QGS is good enough for clinical application. |
