Purpose: To develop an imaging method to characterize and map marrow composition in the entire skeletal system, and to simulate differential targeted marrow irradiation based on marrow composition.

Methods And Materials: Whole-body dual energy computed tomography (DECT) images of cadavers and leukemia patients were acquired, segmented to separate bone marrow components, namely, bone, red marrow (RM), and yellow marrow (YM). DECT-derived marrow fat fraction was validated using histology of lumbar vertebrae obtained from cadavers.

Purpose: The goal of this study was to evaluate whether the addition of a purine analog, cladribine or fludarabine, to the standard induction regimen affects the outcome of adult patients with acute myeloid leukemia (AML).

Patients And Methods: A cohort of 652 untreated AML patients with median age 47 years (range, 17 to 60 years) were randomly assigned to receive one of three induction regimens: DA (daunorubicin plus cytarabine), DAC (DA plus cladribine), or DAF (DA plus fludarabine). Postremission treatment was the same for all arms.
