PET/MRI, 18F-FDG PET/CT and Whole Body MRI in Finding Extramedullary Myeloid Leukemia in Patients with Newly Diagnosed Acute Myeloid Leukemia

PRIMARY OBJECTIVE:

I. To estimate the incidence of extramedullary myeloid leukemia (EML) in patients with newly diagnosed acute myeloid leukemia (AML), by imaging criteria using PET/MR (magnetic resonance), whole body MR, and PET/CT.

SECONDARY OBJECTIVES:

I. To qualitatively and quantitatively assess PET/MR and PET/CR that will be performed with and without fiducial markers, and to correlate these findings with clinical outcomes of treatment response, relapse, and patterns of relapse.

II. Correlate findings of EML as in the primary objectives with clinical outcomes of treatment response, relapse, and patterns of relapse including location of relapse compared to site of EML.

OUTLINE:

Patients receive gadolinium intravenously (IV) and undergo whole body PET/MRI comprising diffusion weighted imaging and 3-dimentional (3D) fast spoiled gradient echo dual echo (FSPGR-DE) with and without fiducial markers. Patients then undergo 18F-FDG PET/CT before start treatment for acute myeloid leukemia.

After completion of study, patients are followed up periodically.
