RESUMEN
Background: chronic hip pain is a common problem in adults. In the absence of a known acute trauma, it can be a diagnostic problem as it can be attributed to many causes. The most common causes are avascular necrosis, inflammatory causes, transient osteoporosis or neoplastic lesions
Aim of the Work: the aim of this study is to evaluate the role of magnetic resonance imaging [MRI] in the evaluation and diagnosis of different causes of chronic hip pain in adults
Patients and Methods: the study was conducted on thirty patients who had chronic hip pain and they were referred to undergo MR imaging of hip joints in MRI Unit in Al-Hussain Teaching Hospital in Thi-Qar / Iraq and Ain Shams University Hospital in Cairo / Egypt
Conclusion: MRI is an essential imaging modality in musculoskeletal system in general and in hip region specifically
Recommendations: MRI should be done preferably with a limited number of sequences. If the diagnosis is still query or whenever inflammation or a neoplastic process is suspected, we should do other sequences in different imaging planes and go for contrast injection and post contrast studies [T1WI]
