|---|---|---|---|
| MWA parameter | |||
| Power (W) | 37.2±1.8 | 37.0±2.5 | 0.66 |
| Time (min) | 6.5±1.2 | 6.3±1.5 | 0.48 |
| Irradiation dose (mSv) | 13.1±1.8 | 12.8±1.2 | 0.39 |
| Technical success rate | 56 (100.0) | 34 (97.1) | 0.20 |
| Hospitalization stay (days) | 3.9±1.8 | 4.1±2.0 | 0.62 |
| Hospitalization cost (USD) | 3,743.8±563.5 | 3,689.5±611.4 | 0.67 |
| Follow up time (months) | 18.5±6.2 | 17.0±8.5 | 0.33 |
Data are presented as mean ± standard deviation or n (%). Irradiation dose (mSV) was calculated as follows: irradiation dose = κDLP × dose-length product (mGy·cm), κDLP =0.015 mSv/mGy·cm. DLP, dose-length product; MWA, microwave ablation.
