To elucidate the spectrum of FAI
To evaluate the role of indirect MR arthrogram in evaluation of FAI
FAI syndrome is a relatively newly described entity in musculoskeletal hip imaging.
Many of the undiagnosed cases of chronic hip pain have been retrospectively diagnosed to be FAI and so the identification of the entity is important since there are specific management protocols for this entity.
The spectrum ranges from the common CAM type variety to the rare PINCER type with the mixed type and secondary types in between .Plain Xrays can suggest some changes in FAI but CT and MR are required for the...
Imaging findings OR Procedure details
All patients with suspected FAI were subjected to plain xray AP of pelvis and hip.MRI was performed in patients having the Xray findings suggestive of FAI .
MR was performed with surface body coils for symptomatic hip from illac crest to the level of lesser trochanterusing 1.5T scanner (Siemen,
Germany) or 3 Tesla scanner (Philips).Indirect MR arthrogram was performed by injecting contrast iv and patient asked to move the affected limb lightly for 10 minutes before the scan.
In addition to the conventional...
Conventional and indirect MR is instrumental in determining the degree of acetabular over /undercoverage and the degree of tear and the amount of cartilage loss in FAI each of which is important for the clinician in the appropriate management of specific cases
