ABSTRACT

INTRODUCTION:

MR and CT are excellent complimentary diagnostic modalities for evaluation of hip pain which are often used together along with radiographs. However, CT involves radiation, which is a concern particularly in younger patients. T1VIBE is a 3D gradient echo MR sequence with high intrinsic contrast between the bone and soft tissues with multiplanar capabilities.

AIM:

We performed a study to assess if TIVIBE can be used to complement MR for evaluation of hip pain in young adults and to see if measurements and angles can be calculated using T1VIBE inversion images with similar accuracy to CT scan. MATERIAL AND

METHODS:

A retrospective review of 50 patients aged less than 40 years, who had MR (including TIVIBE) and CT of pelvis was performed. Post surgical patients were excluded. Some important measurements such as Centre edge angle, Tonnis' angle, anterior acetabular sector angle, posterior acetabular sector angle and acetabular version were independently measured by two readers on T1 VIBE inversion and CT images separately and measurements were compared. One reader performed the measurements again to assess for intra-observer error.

RESULTS:

There was a female predominance (37 F, 13M) with an average age of 27.6 years (range of 17-39). There was no significant difference in the measurements between CT and TI VIBE inversion and there was good intra and interobservor reliability.

CONCLUSION:

TI VIBE inversion sequence can be used as an alternative to CT with added advantage of alleviating the radiation exposure.
