Routine MRI fails to provide direct visualization of bone due to the short tissue relaxation times and limited signal intensity. This study investigates the use of proton density zero echo time (ZTE) MRI for bone in the shoulder. Shoulder CT and ZTE images were acquired for 31 patients. Five measures of osseous defect and lesion sizes were compared between the two modalities. ‘Fair’ to ‘excellent’ intraobserver agreement was observed between CT and ZTE MRI. Zero Echo Time MRI may obviate the need for additional CT evaluation in some cases.
