Description
図5及び図6を参照して述べると、4/8/16/32+検出器横列を備えたマルチ・スライス・スキャナにおいて心螺旋取得を遡及的EKGゲート式再構成と併用した。スキャナ・パラメータは、120kV、300mA、0.5秒回転周期、0.35螺旋ピッチ・ファクタ、1.25mm又は0.625mmスライス厚とし、75%心時相位置でのセグメント分割式再構成を行なった。走査配向は、取得の早い時期により重要なデータを取得するために(患者の運動、例えば呼吸を考慮して)、心臓の下方からとし、心臓の底部から頂部に向かうものとした。心螺旋走査に先立って、冠状静脈洞の原点の近くでタイミング・ボーラス取得を行ない、最適な準備遅延を決定した(造影剤注入の開始時と心螺旋走査の開始時との間の時間)。心画像の走査及び再構成に続いて、画像に運動アーティファクトが認められた場合には全心サイクルにわたって、多時相再構成を指定した。時相位置は、走査時に患者に不整脈が見受けられた場合には約45%に選択した。それでも運動アーティファクトが認められた場合には、マルチ・セクタ再構成を用いた。マルチ・セクタ再構成手順の選択は、多時相後処理3Dビューワを用いると容易になる。最適な画像集合(例えば最適な時相、最適な再構成形式)が選択されて、次いで、検討対象の解剖学的標認点(例えば右房、冠状静脈洞)について特定的な3Dプロトコルによって定義される後処理セグメント分割を実行した。
