  • Title: [Contrast enhancement and morphological findings of hematopoietic regions of bone marrow on MR imaging: comparative study with spondylitis and vertebral tumors].
    Author: Amano Y, Hayashi H, Matsuura M, Watari J, Kumazaki T.
    Journal: Nihon Igaku Hoshasen Gakkai Zasshi; 1995 Jun; 55(7):451-5. PubMed ID: 7644333.
    Abstract:
    The enhanced MR findings of hematopoietic regions in aplastic anemia were compared with those of spondylitis, metastatic vertebral tumors and hematologic neoplasms. The enhanced MR images showed hematopoietic regions to homogeneously enhance and occupy the margin of vertebral bodies, while spondylitis and metastatic tumors appeared as round, inhomogeneously enhancing lesions. MR images of leukemia and myelodysplastic syndrome showed homogeneous enhancement at the margins of vertebrae that was difficult to differentiate from hematopoietic regions. Enhanced MR images were useful in detecting the hematopoietic areas in marrow and differentiating them from spondylitis and metastatic tumors, although further experience is needed to distinguish between tumorous hyperplastic regions and benign hematopoietic regions in marrow.
