Abstract
This study sought to investigate the feasibility of using magnetic resonance-magnetic resonance-ultrasound (MR-MR-US) fusion imaging navigation (FIN) with needle tail intelligent positioning (NTIP) to guide puncture in percutaneous transforaminal endoscopic discectomy (PTED). First, in a pig experiment, we found that puncture errors in lumbar intervertebral foramen (LIF) puncture using magnetic resonance-magnetic resonance-ultrasound (MR-MR-US) FIN with NTIP for experienced and novice operators were 2.00 ± 1.00 and 2.57 ± 0.98 mm, respectively (p = 0.231), suggesting this technique was minimally dependent on experience. Then, two experienced surgeons agreed (inter-observer agreement к=0.801) that the quality of MR-MR fusion images was good or sufficient. Finally, we performed PTED in eight patients using MR-MR-US FIN with NTIP, and no significant complications were reported during LIF puncture. Overall, MR-MR-US FIN with NTIP may be a potential application for guiding puncture in PTED, but more clinical studies with a larger sample size are required to further evaluate the advantages of MR-MR-US FIN with NTIP.
