Highlights
Radiation dose reduction for all procedures vs. control cases was statistically significant at 68% (p < 0.001)
Our study shows that significant reduction in radiation dose without reduction in procedural accuracy can be achieved by lowering the computerized tomography (CT) scanner voltage and current from their default settings
While computerized tomography (CT) guided procedures represent a small portion of total CT examinations, their radiation dose can be significant to both patients and imaging personnel
Summary
While computerized tomography (CT) guided procedures represent a small portion of total CT examinations, their radiation dose can be significant to both patients and imaging personnel. Accuracy for CT-guided needle biopsy of musculoskeletal neoplasms [3]. Artner et al have demonstrated the effectiveness of CT dose reduction strategies during CT-guided spinal, periradicular, and sacroiliac joint injections [5,6,7]. To the authors’ knowledge, no prior studies have examined the effectiveness of CT dose reduction over a wide spectrum of CT-guided musculoskeletal procedures in the adult population. The purpose of the study is to examine the effect of manually reducing CT scanner tube voltage (kVp) and current (mA) on patient radiation dose and procedural effectiveness during CT-guided musculoskeletal procedures on adults
