Fossa supraacetabularis

Age dependent

prevalence of the supraacetabular fossa in children, adolescents and young adults. An example of the placed calipers to perform the measurements on MRI without contrast of the left hip of a 16-years-old, female participant. Proton density weighted (PD) coronal (a) with calipers to measure height and width (a), PD sagittal (b) with calipers to measure depth (b). Dimensions were 6 mm (height), 3 mm (width) mm and 7 mm (depth) (white arrows)

Age dependent

prevalence of the supraacetabular fossa in children, adolescents and young adults. Hip-MRI of a 15-years-old, male participant without contrast with bilateral SAF type 1 (white arrow): Proton density weighted (PD) coronal both sides (a), PD sagittal right side (b), T1 weighted coronal both sides (c) and PD weighted sagittal left side (d)

Age dependent

prevalence of the supraacetabular fossa in children, adolescents and young adults. MR-Arthrography of the hip of a 21-years-old, female participant with SAF type 2 on left side (white arrow): Proton density weighted (PD) coronal (a), T1 weighted sagittal (b) and PD weighted sagittal (c)

Age dependent

prevalence of the supraacetabular fossa in children, adolescents and young adults. 13-years-old female participant with SAF which is partly cartilage filled (white arrow). This example may represent a transitional state from SAF type 1 to SAF type 2: Proton density (PD) weighted (a), T1 weighted coronal (b) and PD weighted sagittal (c)

Age dependent

prevalence of the supraacetabular fossa in children, adolescents and young adults. Radiograph of a 17-years-old female participant with SAF on both sides (white arrow)
