| Abstract | 「要旨」不安定狭心症26例に対して安静時123I-BMIPPシンチグラフィ(BMIPP)と201Tlシンチグラフィ(Tl)を施行し, 有用性と臨床的意義を検討した. 各SPECTは短軸を心基部側と心尖部の2スライス, 16区画と長軸心尖部2区画の18区画に分割した. 集積低下した区画数和をextent score(ES), 各区画の欠損程度の総和をseverity score(SS)として比較した. 冠動脈造影と比較した虚血領域の病変検出率はTlで53.8%(14/26), BMIPPで73.1%(19/26)とBMIPPで優れていた. ESはBMIPPは2.2±2.1, Tlは1.0±1.2とBMIPPが大きかった(p=0.001). SSでもBMIPP 4.9±3.9, Tl 1.6±1.9とBMIPPが大きかった(p<0.001). 重篤な虚血後のBMIPPは, Tlより高率に集積異常を示し, その領域も広く, 虚血領域を示唆していると考えられた. 不安定狭心症では, BMIPPはTlより虚血領域の検出, 特に責任病変の検出に有用であると考えられた. |

| Abstract | The purpose of this study is whether 123I-BMIPP detects a culprit lesion in patients with unstable angina. Twenty-six patients with unstable angina underwent 123I-BMIPP (BMIPP) and 201Tl (Tl) imaging at rest. BMIPP image was compared with Tl imaging. BMIPP imaging revealed defects or low uptake corresponding to myocardial ischemic areas predicted by coronary angiography in 19 (73.1%) of 26 patients. Tl imaging showed defects or low uptake corresponding to coronary angiographic findings in 14 (53.8%). BMIPP demonstrated significantly less uptake than Tl (p=0.001). Severity of reduced BMIPP activity was greater than that of Tl (p<0.001). We concluded that BMIPP imaging was excellent to detecting of culprit lesions in patients with unstable angina. BMIPP SPECT is a sensitive method for detecting myocardium exposed to transient schemia that cannot be detected by Tl imaging. |
