| Diagnostic understanding | |
| 1 | 18F-FES PET confused my understanding of this patient's disease and led to investigations I would not otherwise have done. |
| 2 | 18F-FES PET confused my understanding of this patient's disease but did not lead to any additional investigations. |
| 3 | 18F-FES PET had little or no effect on my understanding of this patient's disease. |
| 4 | 18F-FES PET provided information that substantially improved my understanding of this patient's disease. |
| 5 | My understanding of this patient's disease depended on diagnostic information provided only by 18F-FES PET (unavailable from any other nonsurgical procedure). |
| Therapeutic choice | |
| 1 | 18F-FES PET led me to choose treatment that in retrospect was not in the best interests of the patient. |
| 2 | 18F-FES PET was of no influence in my choice of treatment. |
| 3 | 18F-FES PET did not alter my choice of treatment but did increase my confidence in the choice. |
| 4 | 18F-FES PET contributed to a change in my chosen treatment but other factors (other imaging tests, other diagnostic tests, changes in patient status) were equally or more important. |
| 5 | 18F-FES PET was very important compared with other factors in leading to a beneficial change in treatment. |
