Table 1.

Mean dose length product and effective dose during CT-guided percutaneous cryoablation of liver tumors (n = 20).

Procedural phases Dose length product (mGy*cm)
Effective dose (mSv)
Mean±SD Range Mean±SD Range
Planning 322 ± 150 138–681 4.8 ± 2.2 2–10
Targeting 2496 ± 843 1662–4492 37.5 ± 12.5 25–67
Monitoring 1706 ± 454 937–2825 25.5 ± 6.8 14–42
Post-ablation survey 273 ± 123 135–548 4.1 ± 1.9 2–8
Entire procedure 4796 ± 1214 3059–7784 72 ± 18 46–117

Note: SD, standard deviation. Dose length product and effective dose for each phase were significantly different from each other (p < 0.0001) except for the planning and post-ablation survey phases (p > 0.05).
