合併正子攝影和電腦斷層在卵巢癌的應用

The Role of PET/CT for Ovarian Cancer

摘要


正子攝影/電腦斷層是常用的分子影像技術,有助於婦癌疾病的診斷、分期和復發的偵測。正子攝影/電腦斷層會利用一些參數來增加惡性病灶診斷的準確率,最常用為最大標準攝取值(SUV_(max))。但最近亦增加了代謝性腫瘤體積(MTV)、總病灶葡萄糖溶解量(TLG)、腫瘤內不同成份FDG攝取(IFH)等,均為治療卵巢癌預後判定之重要因子。正子攝影/電腦斷層對全身性可能有的病灶,亦有助復發病灶的判斷。

Positron emission tomography/computed tomography (PET/CT) is the one of the most commonly used molecular imaging techniques in gynecological cancer diagnosis, staging and recurrence detection. Some parameters are used as diagnostic criteria for PET/CT to increase the accuracy of detecting malignancy. The most typical diagnostic criterion parameter is the maximim standardized uptake value (SUV_(max)). Recently, metabolic tumor volume (MTV), total lesion glycolysis (TLG) and even intratumoral 18-fluorodeoxyglucose (FDG) uptake heterogeneity (IFH) have become significent parameters as prognostic factors for ovarian cancer. Whole-body PET/CT is useful for assessment of recurrence of ovarian cancer in the presence of symptom.
