目的:评价18FDG-PET诊断卵巢癌治疗后复发的价值。方法:对54例临床疑有复发的卵巢癌患者进行了18FDG-PET全身及腹部成像,并与CT进行比较。结果:54例临床疑有复发的卵巢癌患者中,病理证实肿瘤复发35例.18FDG-PET检查39/54例显示阳性;CT常规影像检查28/54例阳性。PET、CT监测卵巢癌复发和转移的灵敏度、特异性和准确性分别为100%、78.95%和92.59%;74.29%;89.47%和79.63%。结论:18FDG-PET全身显像作为无创伤性检查技术,能及时探测到复发或扩散肿瘤的代谢变化,可以为卵巢癌术后随访提供一种有效的非侵入性影像学诊断方法。
Objective: To evaluate the value of 18FDG-PET in the diagnosis of ovarian cancer recurrence after treatment. Methods: Whole body and abdominal imaging of 18FDG-PET was performed in 54 patients with recurrent ovarian cancer and compared with CT. Results: Of the 54 patients with recurrent ovarian cancer with clinical suspicion, 35 were recurred by pathology, 39/54 with 18FDG-PET and 28/54 with routine CT examination. The sensitivity, specificity and accuracy of PET and CT in monitoring the recurrence and metastasis of ovarian cancer were 100%, 78.95% and 92.59%, 74.29%, 89.47% and 79.63%, respectively. Conclusion: As a noninvasive technique, 18FDG-PET whole body imaging can detect the metabolic changes of recurrent or diffuse tumors in time and provide an effective and noninvasive imaging diagnostic method for postoperative follow-up of ovarian cancer.
