WebMR findings showed a marked increase in signal intensity on T2WI scans, indicating a prominent increase in free-water content. These abnormal water-like signal intensity patterns in the bone marrow are attributed to the accumulation of acid mucopolysaccharides in hypocellular bone marrow spaces with fatty atrophy ( 4 ). WebThe proximal radial pseudotumour, was defined as a region of marrow signal abnormality with intermediate T1W SE/ T2W FSE/PDW FSE signal intensity between medullary fat and skeletal muscle with hyperintense STIR/PDW FS signal compared to medullary fat, but hypointense to joint fluid.

Web12 feb. 2024 · The alteration in the signal of the bone marrow of the vertebral bodies and both iliac bones can be seen by countless discrete images with hyperintense signals of contours, rounded, diameters of up to 13 mm, which are compatible diffuse commitment by multiple myeloma. In addition, the asymmetry in the size of both kidneys can be observed. Web17 dec. 2008 · The underlying process of hypercellularity of the marrow with loss of fat cells results in the reduction in signal intensity on T1-weighted images. This imaging feature more commonly occurs in conditions such as leukaemia, lymphoma, multiple myeloma and metastatic disease. ficken insurance mount olive
