Structural Imaging and Cognitive Functions in Adult Stem Cell Transplant Recipients Treated With Chemotherapy Alone or in Combination With Radiotherapy

Patients will undergo a brain MRI study and a brief neuropsychological evaluation, at the time of enrollment for controls and prior to undergoing the conditioning treatment required for the stem cell transplant for patients. A follow-up MRI and cognitive evaluation will be performed approximately 12 months after the transplant for patients.

Pt will undergo a Magnetic Resonance Imaging (MRI) study of the brain and a brief neuropsychological evaluation, at the time of enrollment for healthy controls and prior to undergoing the conditioning treatment required for the stem cell transplant for patients (Baseline/Time 1).

A brain MRI study and a brief neuropsychological evaluation will be performed at baseline (Time 1). A follow-up MRI and cognitive evaluation will be performed and about 12 months after the baseline for healthy controls
