Purpose
Recent retrospective studies have suggested that iron overload is a clinically important problem in patients undergoing ablative stem cell transplantation. However, these studies relied on serum ferritin as a surrogate of iron overload, which limits the conclusions that can be drawn from such analyses. Therefore, the investigators are conducting a prospective study to more rigorously examine the prevalence, mechanisms, and consequences of iron overload in this patient population.

| Official Title: | A Prospective Observational Study of Iron Overload in Patients With Acute Leukemia or Myelodysplastic Syndromes Undergoing Myeloablative Allogeneic Stem Cell Transplantation |
- To estimate the prevalence of pre-transplantation iron overload (defined as liver iron content >2 mg/g dry weight by MRI) and of pre-transplantation severe iron overload (defined as liver iron content >7 mg/g dry weight by MRI) [ Time Frame: Pre-transplant ] [ Designated as safety issue: No ]
- To estimate the 6-month and 12-month prevalence of iron overload determined by liver MRI • To compare 6-month and 1-year TRM between patients with severe pre-transplantation iron overload (>7 mg/g dry weight) and those without. [ Time Frame: 1 year post-transplant ] [ Designated as safety issue: No ]
- To compare 6-month and 1-year TRM between patients with pre-transplantation serum ferritin > 2500 ng/ml and those with ferritin ≤ 2500 ng/ml. [ Time Frame: 6 month and 1 year ] [ Designated as safety issue: No ]

Eligibility| Ages Eligible for Study: | 18 Years to 65 Years |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
| Sampling Method: | Probability Sample |
Patient's who are 18 years or older with acute leukema or MDS underdoing a myeloablative allogeneic stem cell transplant
Inclusion Criteria:
- Age ≥ 18 years.
- Histologically confirmed acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), or myelodysplastic syndrome (MDS)
- Planned allogeneic stem cell transplantation with myeloablative conditioning regimen (regardless of stem cell source or donor HLA match)
- Patients will be eligible even if they have had prior stem cell transplantation (autologous or allogeneic)
Exclusion Criteria:
Contraindication to magnetic resonance imaging (MRI):
- Patients with cardiac pacemakers, implanted cardiac defibrillator (ICD), cardiac electrodes, pacing wires, internal electrodes, cochlear, otologic or other ear implants, metallic fragments or foreign body, metallic prosthesis. Patients with surgical staples should not be imaged until 7 days post-op unless approved by a radiologist;
- Severe claustrophobia
- Note: a history of allergic reaction to gadolinium is not a contraindication to enrollment, as contrast will not be used.
- Inability to provide informed consent
