T2-weighted fat suppressed MR images are diagnostically relevant in lesion and critical structure characterization in vascular anomalies, oncology, and cardiology, etc. Current techniques used in MR-guided interventions have limited T2 contrast and fat suppression (e.g SSFP), are slow (e.g. T2W-TSE), or yield blurry images and inferior speed (HASTE). Hence, an imaging technique with sufficient speed for real-time procedure guidance in addition to T2 contrast and fat suppression is of interest. We present contrast-prepared SSFP (CP-SSFP), a technique for interventional guidance incorporating several technical improvements. The technique is evaluated on phantoms and patients undergoing therapeutic or diagnostic imaging for vascular malformations.
