Abstract:
Objective To compare the diagnostic value of X-ray,CT,MRI and SPECT in avascular necrosis of femoral head(ANFH).Methods X-ray,CT,MRI and SPECT findings of ANFH proved by pathology in 180 cases were respectively analyzed and summarized.Results X-ray,CT,MRI and SPECT,the diagnostic sensitivity was 25%,75%,95% and 100% respectively,the diagnostic accuracy was 20%,65%,85% and 85% respectively,and the diagnostic sensitivity and accuracy was 100% and 98% respectively all together of X-ray,CT,MRI and SPECT.Conclusion The diagnostic sensitivity and accuracy of ANFH will observably improve in case of combining X-ray,CT,MRI with SPECT.
