Lumbar epidural injections are typically performed blindly or with fluoroscopic guidance. CT fluoroscopy (CTF) can be used to guide needle placement precisely and rapidly, allowing visualization of the optimal needle path and identifying potential problems such as severe stenosis and synovial cysts before needle insertion. Operator and patient radiation dose is minimal when using the intermittent CTF technique and low mAs. By using this technique, just more than 2000 epidural steroid injections have been performed with no major complications. CTF is a useful guidance tool when performing lumbar epidural injections.
腰椎硬膜外注射通常在盲视下或在荧光透视引导下进行。CT透视（CTF）可用于精确、快速地引导针的放置，在进针前可显示最佳针道并识别潜在问题，如严重狭窄和滑膜囊肿。使用间歇性CTF技术和低毫安秒时，术者和患者的辐射剂量最小。通过使用该技术，已经进行了2000多次硬膜外类固醇注射，无重大并发症。CTF是进行腰椎硬膜外注射时一种有用的引导工具。
