合併正子攝影和電腦斷層在子宮頸癌的應用

The Role of PET/CT for Cervical Cancer

氟18去氧葡萄糖的正子攝影／電腦斷層，可被應用在治療子宮頸癌患者。臨床上，可估計是否有淋巴結轉移，較單獨使用電腦斷層、磁振造影更為準確。正子攝影／電腦斷層亦可作為子宮頸癌預後的判斷。利用這些影像技術，對初始治療、評估復發、計劃救援治療十分重要，熟悉影像有助治療預後的判斷。

18Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) plays central and complementary roles in the care of patients with cervical cancer. For cervical patients with clinically visible tumor, PET/CT is more sensitive than either CT or MRI imaging in the evaluation of nodal involvement. PET/CT has also proved to be a predictor of survival in patients with cervical cancer. Because treatment often requires combinations of surgery, radiotherapy and chemotherapy, imaging is central to triage and to determining prognosis. Use of imaging for initial therapy to assess the recurrence and to plan salvage therapy is also very important.
