| Abstract | 「要旨」 Thallium-201による心筋のSingle Photon Emission Computed Tomography (SPECT) (以下心筋SPECT) は, 左室下壁と心基部中隔の梗塞評価が困難であるといわれている. 心電図同期Technetium-99mによる心プールのSPECT (以下心プールSPECT) は, 梗塞などの評価に有用との報告がある. 今回, 心プールSPECTと心筋SPECTの梗塞の検出能について比較し, いずれが左室下壁・心基部中隔の梗塞の評価に適するか検討することを目的とした. 左室中壁と中隔の梗塞の同一スライス面において比較検討するため, 冠動脈造影・左室造影を行った35例の心プールSPECTと心筋SPECTを同一体位にて収集した・心プールSPECTはCine法とPhase法にて, また心筋SPECTはVisual法とBull's eye法で解析した. 左室下壁において, accuracyは心プールSPECTのCine法が97.1%, Phase法が97.1%であり, 他方心筋SPECTのVisual法は93.9%, Bull's eye法は90.9%であった. 中隔梗塞においてaccuracyはそれぞれ97.1%, 94.3%, 86.2%, 89.6%であった. 下壁の評価において心プールSPECTと心筋SPECTはともに高い検出率を呈した. 中隔の評価において心筋SPECTに比し心プールSPECTがより高い検出率を呈した. 心基部中隔の梗塞評価には心プールSPECTがより有用性が高いと示唆された. |

| Abstract | [Summary] Thallium-201 myocardial single photon emission computed tomography (myocardial SPECT) has been believed likely to miss lesions or false lesions in the inferior wall of the left ventricle and septum in the vicinity of the basis of the heart. In 35 patients having undergone both coronary arterioangiography and contrast left ventriculography, technetium-99m cardiac pool SPECT synchronized with electrocardiography (cardiac pool SPECT) and myocardial SPECT were performed simultaneously. Both cinematographic and phase techniques were used for the cardiac pool SPECT. Visual and Bull's eye techniques were used for the myocardial SPECT. The rate of correct diagnoses made by myocardial SPECT was compared by site with that by cardiac pool SPECT. With the inferior wall of the left ventricle, of diagnoses made by cinematographic and phase techniques of cardiac pool SPECT, 97.0% each was correct. The rates of accurate diagnoses made by visual and Bull's eye techniques of myocardial SPECT were 97.0 and 93.9%, respectively. The rate at which at least one of the SPECT methods was correct was 97.1%. With the septum, the corresponding rates of accurate diagnoses were 97.1, 94.3, 90.0, and 90.9%, with rate of 94.3% at least one of these two methods made correct diagnoses. In conclusion, for diagnosing infarcts of the septal wall of the basis, the cardiac pool SPECT is more accurate than myocardial SPECT. |
