Recommended Administered Activities and Absorbed Doses to Tumors and Lungs Using Different Treatment Planning Methods
| Activity or absorbed dose | Benua–Leeper | Dose-rate method | S value | MCNP4b |
|---|---|---|---|---|
| Administered activity, GBq (mCi) | 4.30 (116.2) | 3.89 (105.0) | 0.66 (17.8) | 1.72 (46.4) |
| Absorbed dose to lungs (Gy) | 177.4* | 160.3* (61.6†) | 27.25‡ | 27.25 |
| Absorbed dose to tumors (Gy) | —§ | —§ (144.2†) | —§ | 63.7 |
↵* Absorbed dose to lungs was calculated using 131I lung-to-lung S value from OLINDA (7).
↵† Absorbed dose in parentheses is calculated using dose conversion factor from MCNP4b transport.
↵‡ MTD to lung tissue was obtained from Press et al. (29).
↵§ Absorbed doses to tumors were not calculated with conventional approach.
