aceUtilization of Magnetic Resonance Imaging-based Synthetic Computed Tomography for Pedicle Screw Navigation in Children: A Feasibility Study
Background: Pedicle screw instrumentation using a fluoroscopy-assisted freehand technique (FAFT) or using navigation based on a preoperative traditional computed tomography (tCT) scan is a common practice. However, concerns remain regarding the long-term effects of repeated ionizing radiation exposure. In 2025, the first pediatric patients in the USA underwent navigated posterior spinal fusions (PSFs) using magnetic resonance imaging (MRI) converted to CT scan-like quality, known as synthetic CT (sCT). The purpo…
Using synthetic CT made from MRI by an AI-mediated algorithm for navigated pedicle screw placement lowered patient radiation exposure compared with traditional CT navigation and freehand fluoroscopy.
The evidence comes from a small retrospective cohort of 20 sCT patients, described as a feasibility study, and fluoroscopy was still needed for some steps.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-1623 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
