【 摘 要 】

and 4, combined interpretation of 1 and 18F-FDG PET/CT). Sensitivity, specificity, accuracy, positive and negative predictive values, likelihood ratios, and diagnostic performance based on the DOR (diagnostic odds ratio) and NND (number needed to diagnose) were evaluated for each interpretation modality, using the pathologic result as the gold standard. Detection rates of seminal vesicle invasion and extracapsular invasion were also evaluated.Results: Integrated 18F-choline PET/MRI showed significantly higher sensitivity than did multiparametric MRI in all patients and low Gleason score patients. Integrated 18F-choline PET/MRI and 18F-FDG PET/MRI showed similar sensitivity and specificity to combined interpretation of multiparametric MRI and 18F-FDG PET/CT. However, integrated 18F-choline PET/MRI showed the best diagnostic performance among the imaging modalities, regardless of Gleason score. Integrated 18F-choline PET/MRI showed higher sensitivity and diagnostic performance than did integrated 18F-FDG PET/MRI.Conclusion: Integrated PET/MRI carried out using a dedicated integrated PET/MRI scanner provides superior accuracy and diagnostic value for detection/localization of prostate cancer. Generally, integrated 18F-choline PET/MRI shows better accuracy and diagnostic performance than does integrated 18F-FDG PET/MRI.
