摘　　要：目的对比前列腺癌患者同期MRI图像及18F-FDG PET/CT图像,初步探讨两种检查方法在前列腺癌分期的临床应用价值。方法选取31例经手术或穿刺活检证实为前列腺癌且在2周内同时行MRI及18FFDG PET/CT检查的患者,对其图像进行回顾性分析。结果前列腺癌A、B期患者PET/CT显像与MRI检查诊断价值相近,C期及D期患者PET/CT诊断价值明显优于MRI。结论前列腺癌早期诊断、分期首选MRI检查,如果MRI检查分期为A期或B期,可直接采用根治性治疗方法,如果MRI检查发现病灶已突破包膜或有局部浸润则建议行18F-FDG PET/CT显像以便全面评估患者状况,选择最佳治疗方案。Objective To compare the MRI images and 18F-FDG PET/CT images of prostate cancer patients over the corresponding period and explore the clinical application value of the two methods in staging prostate cancer. Methods A total of 31 prostate cancer cases diagnosed by operation or biopsy and examined both by MRI and 18F-FDG PET/CT within 2 weeks were selected and the images were analyzed retrospectively. Results The diagnostic values of PET/CT and MRI images were similar in the patients with prostate cancer of stage A or B, while those of PET/CT images were significantly higher than those of MRI images in the patients with prostate cancer of stage C or D. Conclusion MRI examination is the first choice for early diagnosis and staging of prostate cancer. The radical treatment is recommended if prostate cancer is diagnosed at Stage A or B by MRI examination, while 18F-FDG PET/CT imaging is recommended for the comprehensive assessment of the patients＇ condition and the choice of the best therapeutic regimen if the results of MRI examination reveal that the lesion has exceeded the capsule or it has local infiltration.
