Recent availability of arthroscopic treatment options
for young patients with femoroacetabular impingement has
increased the importance of high-resolution hip MRI as a
diagnostic tool. If left untreated, this condition can
lead to premature osteoarthritis. Due to SNR gains,
imaging the hip joints at 7 Tesla is expected to improve
diagnostic precision by accurately assessing the state
of the thin (1-2 mm) acetabular cartilage,. 7T data
obtained with multichannel transmit RF and transmit B1
shim methods suggests that non-enhanced bilateral hip
MRI at ultrahigh fields provide the necessary gains in
contrast and resolution for accurate diagnostic
evaluation of the acetabular cartilage.
