Mira Keyes, MD, Tom Pickles, MD, Alexander Agranovich, MD, Winkle Kwan, MB, B.S., W.James Morris, MD  International Journal of Radiation Oncology • Biology • Physics  Volume 60, Issue 1, Pages (September 2004) DOI: /j.ijrobp

2 Fig. 1 Patient 3. Axial CT images of initial postimplant dosimetry. Prostate, bladder and seminal vesicles were contoured. Isodose lines 145 Gy (100%) and 216 Gy (150%) as marked. Entire base was underdosed. “Day 30” CT postimplant dosimetry: V100 59% and D90 70 Gy. International Journal of Radiation Oncology • Biology • Physics  , 40-50DOI: ( /j.ijrobp )

3 Fig. 2 Patient 3. Two-dimensional reconstructed (a) sagittal and (b) coronal prostate images. Isodose lines 145 Gy (100%) and 216 Gy (150%) as marked. Entire base was underdosed. “Day 30” CT postimplant dosimetry: V100 59% and D90 70 Gy. International Journal of Radiation Oncology • Biology • Physics  , 40-50DOI: ( /j.ijrobp )

4 Fig. 3 Patient 3. Reimplant plan. Initial seeds given in white, additional seeds for reimplant in black. Plan displays 28 additional seeds. Patient was reimplanted with 32 additional seeds, all deposited at base. International Journal of Radiation Oncology • Biology • Physics  , 40-50DOI: ( /j.ijrobp )

5 Fig. 4 Patient 3. Axial CT images of reimplant. Isodose lines 145 Gy (100%) and 216 Gy (150%) as marked. “Day 0” CT postimplant dosimetry: V100 90% and D Gy. International Journal of Radiation Oncology • Biology • Physics  , 40-50DOI: ( /j.ijrobp )

6 Fig. 5 Patient 3. Two-dimensional reconstructed (a) sagittal and (b) coronal reimplant prostate images. Isodose lines 145 Gy (100%) and 216 Gy (150%) as marked. “Day 0” CT postimplant dosimetry: V100 90% and D Gy. International Journal of Radiation Oncology • Biology • Physics  , 40-50DOI: ( /j.ijrobp )

7 Fig. 6 International Prostate Symptom Score (IPSS) in all 7 reimplanted patients. International Journal of Radiation Oncology • Biology • Physics  , 40-50DOI: ( /j.ijrobp )

8 Fig. 7 Median International Prostate Symptom Score (IPSS) for 7 reimplant patients and median IPSS for 400 consecutive cohort patients. International Journal of Radiation Oncology • Biology • Physics  , 40-50DOI: ( /j.ijrobp )
