Abstract

Purpose: Some patients with spinal muscular atrophy and scoliosis require CT guidance during injections of nusinersen. The radiation applied to the operator in such procedures becomes an important issue in terms of staff health and safety. The aim of the study was to assess the operator's radiation exposure during CT-guided nusinersen injections in patients with spinal muscular atrophy and scoliosis.

Methods: Consecutive 40 CT-guided nusinersen injections were analyzed in terms of operator's radiation exposure measured in real time.

Results: The median radiation dose measured under the physician's lead apron and patient dose in terms of DLP was 0.20 µSv and 31.90 mGy*cm respectively. The radiation doses were significantly higher (p = 0.047) in patients with spinal instrumentation.

Conclusion: The results show that CT-guided nusinersen injection is a relatively safe procedure in terms of operator's radiation exposure. This can allow for interventional radiologists to perform more procedures without exceeding their annual dose limit.

实时测量介入放射科医生在 CT 引导下鞘内注射奴西那生时的辐射量。

目的：一些脊髓肌肉萎缩症和脊柱侧弯症患者在注射奴西那生时需要 CT 引导。在此类过程中，操作者所受到的辐射成为影响员工健康和安全的一个重要问题。本研究的目的是评估脊髓性肌肉萎缩症和脊柱侧弯症患者在 CT 引导下注射奴西那森时操作人员受到的辐射量：方法：对连续 40 次 CT 引导的奴西那生注射进行分析，实时测量操作者的辐射量：结果：在医生的铅围裙下测得的中位辐射剂量和以DLP计算的患者剂量分别为0.20 µSv和31.90 mGy*cm。有脊柱器械的患者的辐射剂量明显更高（P = 0.047）：结果表明，CT 引导下的奴西那生注射是一种对操作者辐射暴露相对安全的手术。结论：结果表明，就操作者的辐射暴露而言，CT 引导下的努西那生注射是一种相对安全的程序，这可以让介入放射医师在不超过年度剂量限制的情况下执行更多程序。
