[Bone marrow changes in Hodgkin's disease: MR tomography and chemical shift imaging].

A patient with Hodgkin's disease, who had received various forms of treatment, was examined by MR tomography and scintigraphy; the results are discussed together with the findings of the bone marrow biopsy. A spectroscopic imaging technique (modified Dixon method) and quantitative evaluation of the fat and water components of the RF signal provide new diagnostic information that may improve the differential diagnosis. Serial examinations following supra-lethal therapy and bone marrow transplantation have been able to show changes in the bone marrow and these could be evaluated quantitatively.
