摘要
目的探讨PET/MRI融合图像诊断妇科肿瘤术后盆腔复发、转移的效能。方法回顾性分析38例妇科恶性肿瘤患者术后PET/CT、盆腔MRI图像,并进行PET与MRI图像的融合,比较PET/CT、盆腔MRI及PET/MRI融合诊断盆腔局部复发、转移的价值。结果 38例患者中23例有肿瘤复发、转移,PET/MRI融合图像诊断盆腔复发、转移有较高的敏感度、特异度和准确率,且PET/MRI融合诊断盆腔局部复发的准确率高于MRI(94.73%vs 73.68%,P=0.025)。结论 PET/MRI融合结合了PET和MRI的优势,在诊断妇科肿瘤患者盆腔复发、转移中具有重要的价值。
Objective To investigate the fusion of PET and MRI in detecting intra-pelvic recurrence of gynecological tumor.Methods PET/CT imaging and MRI data of 38 patients with gynecological tumors were retrospectively analyzed. PET imaging and MRI imaging were fused, and the value of fused PET/MRI, pelvic MRI and PET/CT in detecting intra-pelvic recurrence, metastasis were compared.Results Of all 38 cases, 23 patients had recurrence or metastasis. Sensitivity, specificity and accuracy of fused PET/MRI in detecting recurrence or metastasis were high, and the accuracy of fused PET/MRI in diagnosis of local recurrence was signicantly better than that of MRI （94.73% vs 73.68%, P=0.025）.Conclusion Fused PET/MRI combines the individual advantages of MRI and PET, and is a valuable technique for assessment of intra-pelvic recurrence of gynecological cancers.
