摘要: Objective: To assess quantitative and qualitative differences in water components between normal bone marrow reactive hematopoietic aplastic anemia using magnetic resonance (MR) spectroscopy with variable echo times (TEs). Design: Water content, T2 value of the component, signal change related to TE were assessed by a stimulated acquisition mode TEs 30, 45, 60, 90 ms. Patients: Six patients (13–84 years) seven volunteers (25–38 years) examined. Results conclusion: Reactive showed significantly higher content than marrow. The tended be longer ratio was These results suggest difference
