Back pain is one of the most common medical problems and is associated with high socioeconomic costs. Imaging-guided spinal injections are a minimally invasive method to evaluate where the back pain is originating from, and to treat patients with radicular pain or spinal stenosis with infiltration of corticosteroids. CT-guided spine injections are a safe procedure, characterized by precise needle placement, excellent visualization of the relevant anatomical structures, and low radiation exposure for the patient and the interventional radiologist. In this review article, the variety of applications of CT-guided injections (focused on nerve roots and epidural injections) and the optimal injection procedure as well as risks and side effects are discussed.

背痛是最常见的医疗问题之一，并且与高昂的社会经济成本相关。影像引导脊柱注射是一种微创方法，可评估背痛的根源，并通过皮质类固醇渗透来治疗根性疼痛或椎管狭窄的患者。CT 引导脊柱注射是一种安全的手术，其特点是精确的进针位置、相关解剖结构的良好可视化以及患者和介入放射科医生的低辐射暴露。在这篇综述文章中，讨论了 CT 引导注射的各种应用（重点是神经根和硬膜外注射）、最佳注射程序以及风险和副作用。
