TABLE 3.

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.
