New generation low-field MRI systems can be ideal for MRI-guided interventions due to wide bore diameters and lower susceptibility artifacts improving patient access and needle visualization, respectively. We evaluated a set of pulse sequences for their suitability for needle visualization using a new-generation 0.55T system and compared the results with those of a clinical 3T system. Interventional needles can be adequately visualized at 0.55T. Using TSE pulse sequences, needle artifacts display more favorable at 0.55T than 3T. SEMAC and HASTE pulse sequences may not facilitate diagnostic needle visualization at 0.55T but are not needed for clinical MR interventions.
