Legg-Calvé-Perthes disease-MRI

Legg-Calvé-Perthes (LPD) disease is a childhood hip disorder that results in infarction of the bony epiphysis of the femoral head. LPD represents idiopathic avascular necrosis of the femoral head. On mri there is characteristic asterisk sign which is defined as findings of areas of low signal intensity on T1-weighted images and high signal intensity on T2-weighted images in marrow. The double-line sign represents the sclerotic rim, which appears as a signal void. This sign is demonstrated as a line between necrotic and viable bone edges with a hyperintense rim of granulation tissue.
