Aim: To compare the radiation exposure in the group of patients, which were treated by the CT guided minimally invasive methods - pulsed radiofrequency modulation (PRF), oxygen-ozone therapy (OOT) and periradicular therapy (PRT) for chronic sciatica.

Methods: Retrospective analysis of the radiation exposure in cohort of 86 patients, which had undergone one of the forementioned minimally invasive kinds of treatment with intermittent CT navigation, during the period 10/2015 to 06/2017. The radiation exposure was evaluated on the basis of measured total dose length products (DLP) and calculated effective radiation doses (E). Possible influence of periprocedural control CT scans quantity, age and body mass index (BMI) was also evaluated.

Results: Mean DLP in the group PRF was: 33 ± 3.3 mGy.cm, in the group OOT: 35.8 ± 5.8 mGy.cm and in the group PRT: 37.5 ± 7.1 mGy.cm. Mean E in the group PRF was: 0.48 ± 0.096 mSv, in the group KOT: 0.51 ± 0.097 mSv and in the group PRT: 0.55 ± 0.12 mSv. The statistically significant difference of DLP and E values was confirmed between the PRF and OOT, PRT groups (p < 0.05). Also the statistically significant dependence of the DLP and E values to the control scans quantity was confirmed. No statistically significant relationship was found in comparison of the DLP and E to the age and BMI. All procedures have been technically successful. No significant complications of the treatment have occurred.

Conclusion: The radiation exposure in the compared groups was mostly influenced by the quantity of control CT scans. The influence of age and BMI was not statistically significant.
