内容紹介
自動スキャンは手動スキャンよりも正確にvolume dataを取得可能である。この自動スキャンでのvolume dataを用いた治療直前の3D超音波とリアルタイムの2D超音波のUS/US融合画像をRFA中のモニタリングと治療直後効果判定に用いた。US/US融合画像で完全壊死と診断した26例は全例1か月後のCT/MRI で全例完全壊死と判定した。この手技を用いることで、RFA直後の造影CTまたはMRIを省略することも可能と思われる。
Three dimensional US (3D US) is now available using autosweep scanning and this method is anticipated to be of benefit in the clinical setting because 3D image using autosweep scanning can obtain accurate volume data comparing with manual scanning. UA/UA fusion imaging combining 3D US obtained before radiofrequency ablation (RFA) and contrast-enhanced two dimensional US (CE 2D US) obtained during and immediately after RFA using additional software such as global position system (GPS) marks may be a useful modality for monitoring during RFA and immediate evaluation of therapeutic effectiveness of RFA. In this study, 26 HCCs were evaluated as adequate ablation by US/US fusion imaging immediately after RFA and these lesions were also evaluated as adequate RFA by CT or MRI obtained one month after RFA. This modality may cancel the contrast-enhanced CT or MRI immediately after RFA.
