Sickle Cell Disease
Conditions
Keywords
bone marrow cellularity, bone marrow transplant
Brief summary
The primary purpose of this research is to determine if it is feasible to perform serial magnetic resonance imaging (MRI) to evaluate the amount of bone marrow cells (also called cellularity) and iron stores before and after bone marrow transplantation for severe sickle cell disease.
Interventions
All subjects with sickle cell disease undergoing bone marrow transplantation will undergo up to 4 functional MRI scans.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility of obtaining serial scans in patients with sickle cell undergoing marrow transplant | 110 days post transplant | Feasibility will be measured by the number of subjects who undergo at least 2 of 4 scheduled functional MRI's |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| MRI and hemoglobin S. | 1 year post transplant | Correlation between functional MRI result and hemoglobin S level. |
| MRI and neutrophil engraftment | 1 year post transplant | Correlation between functional MRI result and time to neutrophil engraftment |
| MRI and chimerism | 1 year post transplant | Correlation between functional MRI result and time to donor/ recipient chimerism |
