Abstract:
OBJECTIVETo investigate diagnostic value of MRI, X ray and CT for bone infarction in children with systemic lupus erythematosus.
METHODSEleven systemic lupus erythematosus children with bone infarction were retrospectively analyzed from January 2015 to January 2017 , and tested by MRI, X-ray and CT. Among them, including 1 male and 10 females aged from 6 to 16 years old with an average of 13 years old. All patients were detected by MRI, 9 patients were detected by X-ray and 3 patients were detected by CT, imaging findings were analyzed.
RESULTSThe location of bone infarction involved 60 sits, 30 sites located on metaphyseal-diaphyseal region, 8 located on patella, 21 located on epiphysis, and 1 located on talus. Focus of 11 patients were detected by MRI, the main manifestation showed geographic change, long T1 and T2 signal could seen around focus, and showed double ring sign and three ring sign; 5 of 9 patients by X-ray examination detected focus;2 of 3 patients by CT examination detected focus. No abnormity seen at early stage by X-ray and CT examination, and low density focus around harden edge at chronic stage.
CONCLUSIONSMRI could display bone fracture at early stage, X-ray and CT could only display lesion at chronic stage, MRI is the most effective method in diagnosing bone infarction.
