Summary

To investigate the presence of seconday of lymphoid organs in patients who underwent allogenic hematopoietic stem cell transplantation 15 to 45 years ago. The goal aims to assess the development of seconday lymphoid organs given the fact that the absence of myeloablation these patients present a split chimerism between T lymphocytes and the other leucocytes. Thus, they may not be able to generate seconday lymphoid organs. Practically, whole body MRI is being used to visualise and quantify both mediastinal and intraabdominal lymph nodes. Delta will be compared with those obtained in healthy age-matched individuals. It is scheduled to include 15 patients and 15 controls.
