Head-to-head Comparison Between [18F]-FDG PET/CT and PET/MRI in Lymphomas

Head-to-head Comparison Between [18F]-FDG PET/CT and PET/MRI in Lymphomas

Investigating the performance of 18F-FDG PET/CT and PET/MRI in lymphomas

In this study investigators evaluated Nodal and Extranodal Lymphoma Lesions uptake by 18F-FDG PET (PET/CT and PET/MR). Prior to treatment, all patients will undergo whole-body 18F-FDG PET/CT and PET/MR. The methods' efficiency was compared in the diagnosis of lymph node (LN) and organ involvement.

Inclusion Criteria:

• pathologically diagnosed as lymphoma; Written informed consent for receiving PET/MRI after PET/CT examinations. cancer planned chemotherapy or immunotherapy scheme. expected survival ≥ 12 weeks

Exclusion Criteria:

• cannot lie supine for half an hour; refuse to join the clinical researcher; severe liver or kidney dysfunction pregnancy or lactation
