Abstract: This study explored the diagnostic effect and imaging characteristics of magnetic resonance imaging (MRI) combined with multislice spiral CT in avascular necrosis of femoral head. 96 patients with avascular necrosis of femoral head were selected as research subjects. All patients were diagnosed by MRI and multislice spiral CT. The imaging features of each stage and the diagnostic effect of different diagnostic methods on the stage of avascular necrosis of femoral head were compared. The results showed that compared with single MRI and multislice spiral CT, the diagnostic accuracy of MRI combined multislice spiral CT was higher, and the difference was statistically significant (P<0.05). Compared with single MRI and multislice spiral CT, the diagnostic accuracy of MRI combined multislice spiral CT in stage I was higher, and the difference was statistically significant (P<0.05). Compared with multislice spiral CT, the diagnostic accuracy of MRI was higher in stage I, and the difference was statistically significant (P<0.05). MRI combined with multislice spiral CT can effectively improve the diagnostic accuracy of avascular necrosis of femoral head, and improve the diagnostic accuracy of stage I.
