Image-guided treatment of low-flow vascular (venous or lymphatic) malformations presents a challenging visualization problem, regardless of the imaging modality being used for guidance. The purpose of this study was to employ a new magnetic resonance imaging (MRI) sequence, T2-weighted interrupted balanced steady-state free precession (T2W-iSSFP), for real-time image guidance of needle insertion.
