Interactive magnetic resonance imaging-guided biopsy in the head and neck: initial patient experience

The Laryngoscope

Abstract

Because of its excellent soft tissue resolution, magnetic resonance imaging (MRI) can optimize image guidance for interventional and surgical procedures. Notably, needle biopsy of head and neck lesions has been used for years, deeper lesions often requiring some form of image guidance. The closed space of diagnostic MRI scanners proves cumbersome for intervention. The authors report on the first head and neck image-guided biopsies performed in a new, investigational "open configuration" intraoperative MRI scanner. Vertical space between the scanner's upright coils gives access to the patient while imaging; image acquisition is as fast as 2 sec/image. Biopsies were performed on seven patients (parotid, parapharyngeal space, second cervical vertebra); five specimens were diagnostic. Both general anesthesia and intravenous sedation were used. The procedures were without complications. Imaging provided definition of anatomy to direct needle placement. Access to the patient allowed for both percutaneous and transoral approaches. The environment of the open magnet is well suited for biopsy of the head and neck, and near real-time intraoperative MRI has promise for guiding more complex head and neck procedures. Further study should op...Continue Reading
