Simultaneous rest Tc-Sestamibi / I-BMIPP cardiac SPECT imaging has the potential to replace current clinical Tc-Sestamibi rest/stress imaging and therefore has great potential in the case of patients with chest pain presenting to the emergency department. Separation of images of these two radionuclides is difficult, however, because their emission energies are close. The authors previously deve...

と拡張期で内径は顕著には変化しない.しかし,冠動 脈造影の施行例を検討すると,冠動脈が収縮期にのみ 狭窄像を呈し,拡張期には正常化する症例が散見され る.この現象は,通常心外膜側表面を走行すべき冠動 脈が,一部心筋層内を走行し,その結果収縮期に収縮 した心筋により圧迫され,冠動脈造影上狭窄像を呈す ることになる.この所見は機能的変化によるもので, 冠動脈の動脈硬化性病変とは明らかに異なり,臨床的 にも区別して取り扱うことが必要である.このような 現象が心筋ブリッジ(myocardial bridge,または myocardial squeezing)と呼ばれるもので,心筋虚血および 動脈硬化症との関連性が注目されている.以下に myocardial bridge と心筋虚血との関係を示唆する 2 症例 を紹介する. 症例 1:72 歳,女性.発作性心房細動および狭心症 にて外来通院中...
