RT Journal Article SR Electronic T1 The Detection Value of 18F-FDG PET/MR for Breast Cancer Liver Metastasis JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP P1494 OP P1494 VO 64 IS supplement 1 A1 Xu, Yuanfan A1 Xu, Chenjie YR 2023 UL http://jnm.snmjournals.org/content/64/supplement_1/P1494.abstract AB P1494 Introduction: To explore the value of 18F-FDG PET/MR systemic imaging in detecting liver metastasis of breast cancer.Methods: The PET/MR and PET/CT imaging of 78 cases of liver metastasis were analyzed retrospectively. On the same day, whole body 18F-FDG PET/CT imaging and PET/MR imaging were performed, taking pathological and clinical diagnosis as the gold standard to compare the differences in the lesions.Results: 78 patients with liver cancer, a total of 106 intrahepatic metastasis lesions, PET/MR detected all lesions, and PET/CT detected 69 lesions, with significant statistical differences (P<0.01). Among them, 25 lesions were PET-MR positive, while PET-CT was negative; and 19 other lesions were negative for both equipment PET intake. Compared with PET/CT, PET/MR changed the diagnostic results of 28 (35.9%) patients.Conclusions: The detection rate of PET/MR for breast cancer liver metastasis is significantly better than that of PET/CT.
