| Abstract | 「要旨」 回転型ガンマカメラによる 201Tl 心筋 ECT について, 心筋梗塞診断における臨床的有用性を検討した. 心筋梗塞33例を含む61例を対象に, planar image撮像後心筋ECTを施行した. 心筋梗塞に対する診断能をplanar imageと対比した結果, 有病正診率 (sensitivity) 無病正診率 (specificity) 総合正診率 (accuracy) は, planar imageでおのおの75.8%, 92.9%, 83.6%であったのに対し, ECTでは96.9%, 78.6%, 88.5%であった. ECTは有病正診率は明らかに向上するが, 無病正診率は低下し, 総合正診率としてはplanar imageに勝っていた. 心筋梗塞診断に際しては, 3種の断層面 (体軸横断, 矢状断, 前額断) を総合的に判定する必要があると思われた. また, ECT上の梗塞巣のひろがりは心電図所見と比較的よく一致した. |

| Abstract | [Summary] Single-photon emission computed tomography (SPECT) for Tl-201 myocardial imaging using a rotating gamma camera was evaluated for clinical diagnostic efficacy of myocardial infarction. Thirty-three cases with prior myocardial infarction and 28 cases without myocardial infarction were injected with 2-4mCi of Tl-201 at rest. Planar imaging was performed for 5 views (ANT, LAO-30, 45, 60, L-LAT) and followed by SPECT. Overall time of the studies was within one hour. Results were as follows : (1) Sensitivity, specificity and overall accuracy for myocardial infarction diagnosis of SPECT system showed 96.9%, 78.6% and 88.5% respectively. In comparison with planar imaging, SPECT significantly improved sensitivity, however decreased specificity and slightly improved accuracy. (2) Overall interpretation of transaxial, coronal and sagittal images were required for the detection of myocardial infarction. (3) SPECT images showed more clearly findings of infarction than planar imaging and extension of myocardial infarction on SPECT images showed relatively well correlation with ECG diagnosis. |
