Multi-institutional Prospective Pilot Study of Radiology Evaluation of Acute Leukemia Infiltration analyZed by Experimental Imaging REALIZE

What's the purpose of this trial?

This is a prospective pilot study, the primary aim of which is to determine whether the presence of 18F FLT imaging signal uptake abnormalities correlate with clinically validated evidence of hematopoietic malignant disease (e.g. MRD, molecular, flow or histology) after immunotherapy and other treatments.

This trial is currently open and accepting patients.
