Impact of Gated PET/CT in the Diagnosis of Advanced Ovarian Cancer

"PET/CT (without respiratory gating) is performed on an ad-hoc basis in patients with advanced ovarian cancer in the lead up to surgery. The sensitivity of PET/CT for detecting low volume pleural disease is likely reduced by respiratory motion during the ten minute acquisition time over the chest. By freezing this respiratory motion with respiratory gating, we hope that gated PET/CT detection of pleural metastases will improve over non-gated PET images."
