Notably, the intraoperative radiation exposure to patients in the FB CT group (mean 0.361 \u00b1 0.261 mSv) was significantly lower than that in the CB CT group (mean 6.526 \u00b1 13.591 mSv) (p &lt; 0.0001). Furthermore, the intraoperative preparation time for screw placement in the FB group (mean 10.6 \u00b1 5.62 minutes) was significantly lower than that in the CB group (mean 17.6 \u00b1 5.59 minutes) (p = 0.0004). No significant differences were observed for blood loss during surgery, total radiation exposure to surgeons, mean time for inserting a single pedicle screw, revision surgery rate, patients\u2019 reported outcomes, and length of postoperative hospital stay between the two groups. Significant differences were observed for intraoperative radiation exposure to patients and the preparation time for pedicle screw placement.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>The preoperative FB CT-based intraoperative spinal navigation system demonstrated comparable accuracy and safety when compared with the intraoperative CB CT-based system. Moreover, the FB CT-based system had a shorter time for screw placement and reduced intraoperative radiation exposure to patients. These findings support the potential benefits of adopting this novel navigation system to enhance surgical precision and reduce radiation-related risks in MIS-TLIF procedures.<\/jats:p>\n<\/jats:sec>","DOI":"10.3171\/2023.9.spine23422","type":"journal-article","created":{"date-parts":[[2023,11,25]],"date-time":"2023-11-25T01:56:29Z","timestamp":1700877389000},"page":"240-247","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of intraoperative cone-beam CT versus preoperative fan-beam CT for navigated spine surgery: a prospective randomized study"],"prefix":"10.3171","volume":"40","author":[{"given":"Tsung-Hsi","family":"Tu","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi-Hsuan","family":"Kuo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"Institute of Biomedical Informatics, National Yang Ming Chiao Tung University, Taipei;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chih-Chang","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"},{"name":"Department of Biomedical Engineering, School of Biomedical Science and Engineering, National Yang Ming Chiao Tung University, Taipei;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao-Hung","family":"Kuo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"},{"name":"Department of Biomedical Engineering, School of Biomedical Science and Engineering, National Yang Ming Chiao Tung University, Taipei;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hsuan-Kan","family":"Chang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"},{"name":"Department of Biomedical Imaging and Radiological Sciences, National Yang Ming Chiao Tung University, Taipei; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-Yu","family":"Fay","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mei-Yin","family":"Yeh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"},{"name":"Institute of Pharmacology, National Yang Ming Chiao Tung University, Taipei, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chin-Chu","family":"Ko","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Cheng","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jau-Ching","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Neurological Institute, Taipei Veterans General Hospital, Taipei;"},{"name":"School of Medicine, National Yang Ming Chiao Tung University, Taipei;"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"suppl 2","key":"b1","series-title":"Int J Spine Surg","first-page":"S74","article-title":"Image guidance in spinal surgery: a critical appraisal and future directions","volume":"15","author":"Sommer F","year":"2021","unstructured":"Sommer F, Goldberg JL, McGrath L Jr, Kirnaz S, Medary B, H\u00e4rtl R.
