[MR tomography in lymphatic and leukemic bone marrow infiltrations. A comparison with scintigraphy and conventional x-ray diagnosis].

MR is the only noninvasive procedure that can demonstrate changes in the medullary space. If it is combined with bone marrow scintigraphy and conventional x-ray film diagnostics, it can yield a comprehensive diagnosis of bone marrow infiltrations in the regions of the pelvis, thighs and lumbar vertebral column in leukaemia or malignant lymphomas. The T1 relaxation times of the malignant infiltrations are enhanced compared with normal fatty marrow. MR tomography of the bone marrow is particularly suitable for determining the therapy or follow-up control of a malignant systemic disease.
