Rogits B, Jungnickel K, Lowenthal D, et al. Prospective Evaluation Of The Radiologist’s Hand Dose In CT-Guided Interventions. Röfo. 2013 Nov;185(11):1081-1088.

Assessment of radiologist’s hand dose in CT-guided interventions and determination of influencing factors. 138 CT-guided interventions (biopsy n = 99, drainage n = 23, pain therapy n = 16) at different locations (lung n = 41, retroperitoneum n = 53, liver n = 25, spine n = 19) were included. The lesion size was 4 – 240 mm (median: 23 mm). The fluoroscopy time per intervention was 4.6 – 140.2 s (median: 24.2 s). The measured hand dose ranged from 0.001 – 3.02 mSv (median: 0.22 mSv). The median hand dose for lung puncture (n = 41) was slightly higher (median: 0.32 mSv, p = 0.01) compared to that for the liver, retroperitoneum and other.
