Abstract:
[Objective]To probe the standard of early diagnosis of femoro-acetabular impingement(FAI),and the imageological appearance of 16 row spiral CT noncontrast enhanced scan and three-dimensional reconstruction,and MRI of progression of FAI patients.And to approach the significance of using the imageology result to identity doubtful FAI patients with other patients.[Methods]Six FAI patients were enrolled.CT and MRI noncontrast enhanced scan and CT three-dimensional reconstruction were performed to assess the hip joint.The CT scan was performed on the GE Lightspeed 16 row spiral at 1.25 mm slice reconstruction.The MRI scan was performed on the Siemens Avanto 1.5T supraconduction magnetic resonance meter.The CT and MRI scan included the acetabulum to the lesser trochanters.[Results]The results of DR of pelvis orthophoria discovered subtotal congenital anatomic abnormality of hip.The result of 16 row spiral CT noncontrast enhanced scan and three-dimensional reconstruction discovered total congenital anatomic abnormality of hip.The result of MRI noncontrast enhanced scan discovered phlegmasia of hip joint of midanaphase patients of FAI.[Conclusion]Non-buninoid femoral head,hyper-deep of hip,acetabular anteversion and hypsokinesis,and typical sings and symptoms lead to early and exactitude diagnosis.The results of 16 row spiral CT three-dimensional reconstruction and MRI can provid straight reference operation schedule;The result of MRI noncontrast enhanced scan can detect FAI with early avascular necrosis of the femoral head.
