الوصف: Purpose: PET/MRI can provide simultaneous whole-body (WB) acquisition of T1,T2DIXON, Diffusion Weighted Images (DWI), Dynamic Contrast-Enhanced (DCE), and FDG-PET sequences. The objective of this study was to assess and compare the diagnostic performance of 4 combinations of these sequences for baseline staging of patients with monoclonal gammopathies (MG). Materials and methods: 104 patients with MG were included in this IRB approved study. Readers reviewed initial PET/MRIs for the presence of focal lesions (FL) and bone marrow infiltration (BMI) using 4 different image datasets: WB-MRI (including DWI), 3DT1-PET, WB-PET/MRI and WB-DCE-PET/MRI. A reference standard was established by a panel review of all baseline and follow-up imaging, biological and pathological data. The diagnostic performance for each image dataset to detect FL and BMI were evaluated and compared (Fisher’s exact test). Results: The sensitivity, specificity and accuracy for FL of WB-MRI was 87, 97 and 92%; of 3DT1-PET was 78, 97, and 95%; of WB-PET-MRI was 93, 97, and 95%; WB-DCE-PET-MRI was 93, 97, and 95%. The sensitivity of WB-PET-MRI and WB-DCE-PET-MRI were superior to 3DT1-PET (p=0,036) without decreasing specificity. The sensitivity, specificity and accuracy of WB-MRI for BMI was 91, 80 and 85% ; of 3DT1-PET was 53, 89, and 74% ; of WB-PET-MRI was 98, 66, and 79% ; of WB-DCE-PET-MRI was 98, 59, and 75%. 3DT1-PET lacked sensitivity compared to all other datasets (p<0.0001). WB-MRI had better sensitivity than 3DT1-PET (p<0.001) and specificity than DCE-PET/MRI (p<0.001). Conclusion: PET/MRI should combine both WB bone marrow dedicated MRI and FDG PET images with no added value of DCE for baseline staging. ; L’objectif de cette étude était d'évaluer et de comparer les performances diagnostiques de 4 combinaisons de séquences en TEP/IRM pour le bilan initial des patients atteints de gammapathies monoclonales (GM).
