[Abstract] Objective: To study the imaging appearance and measure the ADC value with MR diffusion weighted imaging in healthy adult femoral head and neck. To provide normal reference rules to evaluate femoral diseases with MR-DWI.Materials and Methods: DWI was performed in 90 healthy volunteers. Forty-two males and 48 patients with age between 24 and 78 years (mean age of 57.3 years). These volunteers have no clinical symptoms, no any disease, surgery and trauma affecting hip joint and pelvic. Conventional MR imagings show normal hip joint. EPI-DWI were performed in GE 1.5 T MR unit, b values were 300, 500 and 700 s/mm2. The ADC of femoral head and neck of each volunteers were measured and compared among different positions. Then analyzed statistically.Results: In different b values 300 s/mm2, 500 s/mm2, 700 s/mm2, the mean ADC value of femoral heads were (3.63±1.34)×10-4 mm2/s, (1.87±0.76)×10-4 mm2/s, (1.49±0.53)×10-4mm2/s, the mean ADC value of femoral necks was (5.36±1.50)×10-4 mm2/s, (3.75±1.03)×10-4 mm2/s, (3.54±0.93)×10-4 mm2/s. There were significant statistical differences in ADC values of femoral head and femoral neck in different b values (P<0.05).Conclusion: This study obtained the ADC values ranges of femoral head and neck in normal adult. The results is useful for clinical application of DWI and provide a valuable reference value in scientific research work of femoral head diseases.
