3. Fig. 2
(a) Supine and (b) weight-bearing radiographs of the hip. Note the weight bearing view has overlying pannus that degrades image quality. Either image could be used to measure joint space width.

4. Fig. 3
Standard MRI examination of the hip with two-dimensional fast or turbo spin-echo sequences. (a) Axial intermediate weighted MRI without fat suppression. (b) Axial T2-weighted MRI with fat suppression. (c) Coronal intermediate weighted MRI with fat suppression. (d) Coronal T1-weighted MRI without fat suppression. (e) Sagittal intermediate-weighted MRI with fat suppression. All relevant anatomy (bone, cartilage, joint fluid, labrum) can be evaluated on these images.

6. Fig. 5
T1rho (left) and T2 (right) color maps of the hip in a healthy volunteer, for evaluation of cartilage matrix properties. T2 is correlated with collagen organization, and T1rho with proteoglycan content.

(a) Coronal reformation of computed tomography study of the pelvis, demonstrating os acetabuli (arrow). (b) Three-dimensional shaded-surface display of the same hip, shown from a sagittal orientation. Arrows show the os acetabuli.

8. Fig. 7
T1-weighted fat-suppressed images from an MRI arthrogram in a subject with a history of femoroacetabular impingement. (a) Coronal image showing a labral tear (arrow). (b) Sagittal image showing an anterior labral tear. (c) Oblique axial image for measurement of alpha angle.
