Arthrographie des Hüftgelenks

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Opacified ilio-psoas recess and osteoarthritis in a 45-year-old man. Axial fat-saturated T1-weighted 3D gradient echo image shows the ilio-psoas recess filled by contrast medium and containing some small post-injection bubbles (white arrow). Moreover, heterogeneous signal of the labrum and pericephalic osteophytes are consistent with osteoarthritis

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Intra-articular injection in a right hip joint under fluoroscopic guidance. Puncture site (white arrow) is at the superior part of the anatomical neck of the femur but the middle part could have been chosen (white arrowhead)

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Normal hip joint. Coronal fat-saturated T1-weighted arthro-MR image demonstrates a perilabral recess (white arrow). The superior labrum has a normal triangular shape and an homogeneous low signal (white arrowhead)

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Normal variant of the posterior labrum. On this axial oblique fat-saturated T1-weighted image of a 17-year-old girl’s hip, a linear interposition of contrast medium separates partially the underside of the posterior labrum (white arrow), consistent with a posterior sublabral recess. The signal of the labrum is normal, and its rounded shape is also a normal variant

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Elementary labral lesions on fat-saturated T1-weighted arthro-MR images. a Axial oblique image. Irregular anterior labrum appearing of undefined degenerative high signal, without formal evidence of tear. b Coronal image. An horizontal well-defined high-signal line visible within the superior labrum is consistent with a flap tear of the labrum. Moreover, cartilaginous thinning, osteophytes and a tear of the superior capsule are detected. c Sagittal image shows a peripheral vertical linear hyperintense line in the labrum at 2 o’clock. As it communicates with the articular surface but not with the perilabral recess; it is consistent with a partial longitudinal labral tear. d Sagittal image shows a complete longitudinal labral tear at 2 o’clock

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Axial fat-saturated T1-weighted arthro-MR image. This curvilinear hyperintense line visible on the articular side of the anterior labrum (white arrow) consistent with a partial tear can be asymptomatic

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Coronal reconstruction from a fat-saturated 3D gradient echo acquisition. A paralabral cyst is opacified by contrast media through a complete labral tear of the superior labrum

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. This coronal fat-saturated T1-weighted arthro-MR image shows degenerative changes associated with a slight hip dysplasia: the superior labrum is irregular and of intermediate signal. Small pericephalic osteophytes are also present

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Cam-type of FAI: anterior bulge of the head-neck junction (white arrow) and increased alpha angle (69 degrees vs 55 degrees maximum). Anterior labrum is torn off and calcified

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Sagittal fat-saturated T1-weighted arthro-MR image shows a complete thinning of femoral and acetabular cartilage at the superior aspect of the joint associated with subchondral high-signal consistent with subchondral oedema

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. Axial oblique fat-saturated T1-weighted arthro-MR image shows a hypointense structure wholly surrounded by contrast medium consistent with an intra-articular foreign body (white arrow

Magnetic

resonance arthrography of the hip: technique and spectrum of findings in younger patients. a, b Complete tear of the ligamentum teres in an 29-year-old man. a Coronal reconstruction from a fat-saturated 3D gradient echo acquisition: the acetabular insertion of the ligamentum teres is interrupted. The ligamentum teres has an abnormal intermediate signal. b Sagittal fat-saturated T1-weighted arthro-MR image through the acetabular bottom shows a laminated ligamentum teres completely vertically divided into two parts (white arrows)
