Abstract: In order to study the values of MR/CT to the diagnosis, differential diagnosis, treatment and prognosis of systemic lupus erythematosis with neuropsyehiatric disorders (SLE-NP), MR/CT image changes of 22 examinations of skull/spinal cord in 16 patients with SLE-NP were analyzed. The results showed that the images of 18 examinations were abnormal (81.8%), including ischaemia/infarct (9 times), haemorrhage (3 times), focal demyelination (3 times), and cerebral atropy (6 times). The areas involved including basal ganglia (10 times), anterior horn of lateral ventricle (5 times), pons (1 time), and spinal cord (2 times). MR/CT is sensitive for the examination of lesions of SLE-NP, and the total positive rate is as high as 81.8%. Its high resolution rate can display the nature and areas of the lesions, which may provide valuable reference for the early diagnosis, differential diagnosis, treatment, evaluation of therapeutic efficacy and prognosis of SLE-NP.
