Performance of PET/CT Versus Conventional Imaging Work-up to Depict Distant Metastases in Overall Series
| Site | PET/CT | Bone scanning | Chest imaging (radiography or dedicated CT) | Abdominal imaging (sonography or enhanced CT) | Total* |
| Bone metastases | 30 | 23† | — | — | 30 |
| Lung metastases | 6‡ | — | 7 | — | 7 |
| Pleura | 2 | — | 1 | — | 2 |
| Distant lymph node metastases | 19 | — | 10§ | 1 | 19 |
| Liver metastases | 10 | — | — | 9║ | 10 |
↵† 19 positive bone scans and 4 suggestive nonequivocal bone scans.
↵* In total, 43 patients had distant metastases. Some women had metastases in different viscera.
↵‡ Two women with lung metastases had no 18F-FDG uptake; metastases were detected only on CT part of PET/CT imaging.
↵§ Among 19 patients with lymph node metastases detected by PET/CT, 18 were positive in supradiaphragmatic area. All these patients had chest radiography, and 13 had dedicated chest CT.
↵║ Among 10 patients with liver metastases, 7 had liver sonography and 8 had abdominal enhanced CT.
