Abstract:
Objective To study the diagnostic values of X-ray,CT and MRI for the hip joint lesion of the patient with ankylosing spondylitis (AS).Methods Totally 180 AS patients underwent the examinations of X-ray,CT and MRI from January 2014 to December 2015,and the hip joint lesion,clinical features and the efficacies of the three imaging techniques were observed.Results The rates for positive findings were 69.44％,71.11％ and 72.22％ respectively by X-ray,CT and MRI,and more than 90％ patients had the lesions occurred at the bilateral hip joints simultaneously.Hip joint lesion of AS had the imaging features of bone marrow and joint space changes,which related to the disease progress closely.Early positive signs consisted of medial joint space narrowing by X-ray,rear joint space narrowing by CT as well as bone marrow fat deposition (BMFD) and bone marrow edema (BME) by MRI.Conclusion X ray,CT and MRI all gain their advantages when used to diagnose the hip joint lesion of AS.X-ray behaves well in early diagnosis of medial joint space narrowing,while have disadvantages in displaying soft tissues and minute structures when compared with CT and MRI.CT displays the minute structure of hip joint clearly,and is not so good at soft tissue resolution as MRI.MRI gains the highest resolution for displaying soft tissues in the three techniques,and can show BMFD,BME and etc which can not be revealed by X-ray and CT.
