Jakubovic R, et al. - Researchers presented their initial experience using high-frequency micro-ultrasound (μUS) imaging during spinal procedures, assuming that dynamic feedback achieved during surgery by fusing μUS with pre-operative imaging and tracking the ultrasound probe intra-operatively using the optical topographic imaging technology could affect clinical decision making. During spine surgery, obtaining micro-ultrasound images revealed exquisite detailing of the spinal anatomy including white matter and gray matter tracts and nerve roots and enabled accurate assessment of the extent of decompression/tumor resection. Tracked μUS facilitated real-time imaging of the surgical cavity, providing relevant qualitative improvement over conventional ultrasound.
