Abstract:This study aim to evaluate the diagnostic value of MRI in assessment of painful hip joint. Background: Radiographic evaluation is crucial in patients with painful hip joint. Hip pain has different etiologies in adults and children. MRI is the method of choice in characterizing the various disorders and assessing the full extent of osseous, chondral and soft tissue abnormality of the hip joint. Methods: This prospective study included 100 patients with painful hip joint. The following MR sequences were performed to all patients: Coronal T1, T2 & STIR WIs, axial T1&T2WIs, axial T1WI and sagittal T1WI after contrast injection. Patient's history, local examination of the diseased hip and laboratory investigations were performed. Results: Male to female was 45 to 55, their ages ranged from 10 to 60 years with a mean age of 35 years. The MRI sensitivity were as follows 88% in avascular necrosis, 80% in osteoarthritis,90% in migratory osteoporosis, 100% in transient synovitis, 72% in septic arthritis, 80% in Perthe's disease, 80 % in tumor, 100% in inflammatory lesions 75% in slipped femoral epiphysis and 100% in stress fractures . Conclusion: MRI of the hip joint is an informative, diagnostic, and accurate for the assessment of hip pain and sufficient imaging modality for delineation of different hip joint pathology.
