Integrated PET-CT best for detecting recurrent ovarian ca.(Gynecology)
CHICAGO -- The accuracy of PET-CT for detecting recurrent ovarian cancer is high, Dr. Sunit Sebastian said at the annual meeting of the Radiological Society of North America.
The diagnosis of early recurrence is challenging due to the small size of peritoneal metastases, he said.
In a retrospective study, integrated PET-CT imaging proved to be more accurate than CT alone or PET alone for detecting ovarian cancer recurrence either above or below the diaphragm, reported Dr. Sebastian, who was at Massachusetts General Hospital in Boston at the time of the study.
The analysis included 54 consecutive CT, PET, and PET-CT examinations that were performed at the hospital on 53 women for tumor recurrence after primary debulking surgery for histologically proven ovarian cancer.
One patient underwent PET-CT examination twice.
PET-CT scans of the neck, chest, abdomen, and pelvis were performed with negative oral contrast on a fusion PET-CT scanner.
Delayed PET images were obtained 1 hour later. Finally, a diagnostic CT scan was performed with intravenous contrast and negative oral contrast.
