Our objective was to estimate patient radiation exposure during fluoroscopy with either a fixed table or portable C-arm using a validated anthropomorphic adult male model. METHODS A validated male anthropomorphic model was placed supine on both a cystoscopy operating room table and a fixed fluoroscopy table unit. A GE 9900 C-arm was used to perform fluoroscopy with the cystoscopy table. Metal oxide semiconductor field effect transistor dosimeters were placed at 20 organ-specific locations in the model to measure organ specific dosages. Continuous fluoroscopy was performed for three separate 5-6 minute runs. Measured organ dose rates (mGy/sec) were multiplied by their tissue weighting factor (International Commission on Radiological Protection) and summed to determine effective dose rate (EDR, mSv/sec). Values are reported as mean ± SD. RESULTS The total EDR was significantly higher by an order of magnitude during fixed-table compared with portable C-arm fluoroscopy at 0.0240 ± 0.0019 mSv/sec and 0.0029 ± .0005 mSv/sec, respectively (p = 0.0024) . The organ specific dose rates are presented in the figure. The bone marrow, liver, stomach, spleen, pancreas and gallbladder were all exposed to significantly greater doses with the fixed table compared to the C-arm. CONCLUSIONS Estimated organ doses and EDR are significantly higher during fluoroscopy using fixed-table compared with portable C-arm fluoroscopy. The majority of organs, including the most radio-sensitive organs, are exposed to more radiation using the fixed table. Urologists should be aware of this difference when considering operating room design and purchasing fluoroscopy equipment to perform ureteroscopy or percutaneous nephrolithotomy. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e109 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Fernando Cabrera More articles by this author Richard Shin More articles by this author Giao Nguyen More articles by this author Chu Wang More articles by this author Yi Hsuan Chung More articles by this author Ramy Youssef More articles by this author Charles Scales More articles by this author Michael Ferrandino More articles by this author Glenn Preminger More articles by this author Terry Yoshizumi More articles by this author Michael Lipkin More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
