Abstract「要旨」Wolff-Parkinson-White (WPW) 症候群において位相解析による副刺激伝導路の位置推定が試みられてきたが, 従来の位相イメージではその正確な位置推定には限界があった. そこで7ピンホール断層法およびgated emission computed tomography (ECT) に位相解析を応用し, その精度を検討した. 対象はWPW症候群21症例, 正常者3例, 計24例であり, 副刺激伝導路は17例において手術により確認された. 7ピンホール断層法では, 左心型6例中5例でその位置推定はほぼ可能であった. 一方, gated ECTによる位相解析は9例中8例でその副刺激伝導路の位置がほぼ推定でき, 1例では2本の副刺激伝導路のうち1か所と早期収縮部位が一致した. 断層法の位相解析は従来の位相イメージと比較して, 血液プールの重なりを避けることができ, 3次元的な位相の進行が評価できる点で優れており, 精度の向上が期待できる.

Abstract[Summary] Phase analysis of gated blood pool study has been applied to detect the site of accessory conduction pathway (ACP) in the Wolff-Parkinson-White (WPW) syndrome; however, there was a limitation to detect the precise location of ACP by phase analysis alone. In this study, we applied phase analysis to gated blood pool tomography using seven pin hole tomography (7PT) and gated emission computed tomography (GECT) in 21 patients with WPW syndrome and 3 normal subjects. In 17 patients, the sites of ACPs were confirmed by epicardial mapping and the result of the surgical division of ACP. In 7PT, the site of ACP grossly agreed to the abnormal initial phase in phase image in 5 out of 6 patients with left cardiac type. In GECT, phase images were generated in short axial, vertical and horizontal long axial sections. In 8 out of 9 patients, the site of ACP was correctly identified by phase images, and in a patient who had two ACPs, initial phase corresponded to one of the two locations. Phase analysis of gated blood pool tomography has advantages for avoiding overlap of blood pools and for estimating three-dimensional propagation of the contraction, and can be a good adjunctive method in patients with WPW syndrome.
