Evaluation of T1rho Magnetic Resonance Imaging for Diagnosis of Cartilage Lesions in Hips With Developmental Dysplasia

Patients will undergo 2 different MRIs of the affected hip. Both MRIs assess hip cartilage degeneration. A contrast agent, Gadolinium, will be used to visualize cartilage during the MRI. The contrast agent is injected through an intravenous (a small plastic tube inserted into a vein in the patients' arm) before the MRI.
