MR imaging-guided adrenal biopsy using an open low-field-strength scanner and MR fluoroscopy.

Objective: The aim of our study was to test the feasibility and specific properties of MR imaging-guided adrenal biopsy using an open 0.2-T scanner and MR fluoroscopic fast imaging with steady-state free precession sequences.

Conclusion: MR imaging-guided biopsy of the adrenal gland is feasible and safe. In all patients, appropriate specimens were obtained with full diagnostic yield and accuracy. MR fluoroscopy is particularly useful to establish an oblique paravertebral access without pleural transgression. For final needle placement, supplementary breath-hold multislice sequences are required in most cases.
