“…However, not all small tumors can be localized by fusion imaging and/or CEUS as the detectability at US is intrinsically limited by the sonographic window and the location and size of the target lesion. Given that MR guidance has several advantages, such as the near real-time guiding capability of MR fluoroscopic imaging, higher sensitivity in detecting small hepatic lesions, ability to monitor tissue temperature during ablation, free selection of imaging planes, and absence of ionizing radiation hazards [169,170], MRI may be used as an alternative guiding modality for small HCCs inconspicuous on fusion imaging and/or CEUS [167]. However, MR-compatible devices are required for MR-guided ablation procedures.…”

The first edition of the guidelines for the use of ultrasound contrast agents was published in 2004, dealing with liver applications. The second edition of the guidelines in 2008 reflected changes in the available contrast agents and updated the guidelines for the liver, as well as implementing some nonliver applications. The third edition of the contrast-enhanced ultrasound (CEUS) guidelines was the joint World Federation for Ultrasound in Medicine and Biology-European Federation of Societies for Ultrasound in Medicine and Biology (WFUMB-EFSUMB) venture in conjunction with other regional US societies such as Asian Federation of Societies for Ultrasound in Medicine and Biology, resulting in a simultaneous duplicate on liver CEUS in the official journals of both WFUMB and EFSUMB in 2013. However, no guidelines were described mainly for Sonazoid due to limited clinical experience only in Japan and Korea. The new proposed consensus statements and recommendations provide general advice on the use of Sonazoid and are intended to create standard protocols for the use and administration of Sonazoid in hepatic and pancreatobiliary applications in Asian patients and to improve patient management.

“…Magnetic resonance imaging (MRI) as guidance modality is less commonly used; nevertheless, it offers several advantages such as near real-time fluoroscopic imaging, free selection of imaging planes, monitoring of thermal effects, and absence of ionizing radiation [16,17]. Furthermore, the high soft tissue contrast enables tumour localisation and evaluation of the ablation zone in most cases without additional use of contrast agent [18].…”

Synopsis Interventional MR uses rapid imaging to guide diagnostic and therapeutic procedures. One of the attractions of MR-guidance is the abundance of inherent contrast mechanisms available. Dynamic procedural guidance with real-time imaging has pushed the limits of MR technology, demanding rapid acquisition and reconstruction paired with interactive control and device visualization. This article reviews the technical aspects of real-time MR sequences that enable MR-guided interventions.
