Due to short tissue relaxation times and signal scarcity, routine MRI does not provide direct visualization of bone. This study investigates the use of proton density zero echo time (ZTE) MRI of bone in the hip, with emphasis on femoroacetabular impingement (FAI). Hip CT and ZTE images were acquired for 24 hips (14 patients). Ten measures of osseous morphology were compared between modalities. 'Moderate' to 'excellent' agreement was seen in all but one of the measurements. Zero Echo Time MRI may mitigate the need for CT in some cases.
