The anteroposterior (AP) dimension of the glenoid was measured at the glenoid equator and after soft tissue layer closure the specimen underwent scanning (CT, 1.5\u2010T MRI, and 3\u2010T MRI) with the following methods (0%, 10%, and 25% defect by area). Raw axial data from the scans were segmented using manual mask manipulation for bone and reconstructed using Mimics software to obtain a 3D en face glenoid view. Using calibrated Digital Imaging and Communications in Medicine images, the diameter of the glenoid at the equator and the area of the glenoid defect was measured on all imaging modalities.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In specimens with 10% or 25% defects, no difference was detected between imaging modalities when comparing the measured defect size (10% defect\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .27, 25% defect\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .73). All 3 modalities demonstrated a\u00a0strong correlation with the actual defect size (CT, \u03c1\u00a0= .97; 1.5\u2010T MRI, \u03c1\u00a0= .93; 3\u2010T MRI, \u03c1\u00a0= .92,\n                      <jats:italic>P<\/jats:italic>\n                      &lt; .0001). When looking at the absolute difference between the actual and measured defect area, no significance was noted between imaging modalities (10% defect\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .34, 25% defect\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .47).

Regardless of imaging modality, the error in bone loss measurement tends to increase with increased defect size. Use of 3D MRI in the setting of shoulder instability could obviate the need for CT scans.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Relevance<\/jats:title>\n                    <jats:p>The goal of our work was to develop a reproducible method of determining glenoid bone loss from 3D MRI data and hence eliminate the need for CT scans in this setting. This will lead to decreased cost of care as well as decreased radiation exposure to patients. The long\u2010term goal is a fully automated system that is as approachable for clinicians as current 3D CT technology.<\/jats:p>\n
