Sabat S, Slonimsky E. Radiation Reduction in Low Dose Pulsed Fluoroscopy versus Standard Dose Continuous Fluoroscopy during Fluoroscopically-Guided Lumbar Punctures: A Prospective Controlled Study. J Clin Imaging Sci. 2018 Mar 9;8:9.

The purpose of this study was to evaluate radiation dose reduction in fluoroscopically guided lumbar punctures (FGLP) using “pulsed fluoroscopy in a low dose mode” compared with the commonly used “continuous fluoroscopy in a standard dose mode” while maintaining the technical success. Average entrance surface dose of the study group was significantly lower (3.81 mGy [range: 0.21–11.14, [±2.8 SD]]) compared with the control group (22.45 mGy [range: 1.23–73.44, [±19.41 [SD]]). The average DAP of the study group (10 mGy·cm2 [range: 1–41, [±9.8 SD]]) was also significantly lower than the control group (65 mGy·cm2 [range: 5–199, [±53 SD]]).
