RESUMO
Objective To analyze the MRI characters of hemodialysis-related osteoarthropathy in long-term dialysis recipients, and to evaluate the diagnostic value of X-ray, CT, and MRI on hemodialysis-related osteoarthropathy. Methods The shoulders, hips, wrists and lumbar vertebraes of 32 patients underwent X-ray and CT examinations. Twenty-six of them received MRI examinations. Results In X-ray of 32 patients, 28 appeared osteoporosis, 11 showed bone resorption, 6 had cystic lesions, 11 had bone sclerosis, 1 had joint swelling, and 19 had soft tissue calcification. In CT of 32 patients, 32 appeared osteoporosis, 9 showed bone resorption, 12 had cystic lesions, 11 had bone sclerosis, 3 had joint swelling, and 19 had soft tissue calcification. In MRI of 26 patients, 6 appeared osteoporosis, 2 showed bone resorption, 14 showed cystic lesions, 5 had bone sclerosis, 15 had joint swelling, and 1 showed soft tissue calcification. Conclusions X-rays plain film is the first choice for the diagnosis of hemadialysis-related osteopathy, and MRI is the first choice for the diagnosis of hemedialysis-related arthropathy. CT and MRI is pretty useful in the diagnosis of hemodialysis-related osteoarthropathy.
