“…In these cases, the loss of bone anteriorly coupled with the remaining non-circular margin resulted in incorrect estimation of the native bone contour (Figure 6). Other authors have noted similar limitations when using the best-fit circle method [18, 25]. However, we found that measuring glenoid diameters using IR-UTE-Cones and 2D CT were very accurate when compared to our reference standard of 3D CT and reliable between raters.…”

Objective To utilize the 3D Inversion Recovery prepared Ultrashort-Echo-Time with Cones Readout (IR-UTE-Cones) MRI technique for direct imaging of lamellar bone with comparison to the gold standard of computed tomography (CT). Materials and Methods CT and MRI was performed on 11 shoulder specimens and 3 patients. Five specimens had imaging performed before and after glenoid fracture (osteotomy). 2D and 3D volume-rendered CT images were reconstructed and conventional T1-weighted and 3D IR-UTE-Cones MRI techniques were performed. Glenoid widths and defects were independently measured by two readers using the circle method. Measurements were compared with those made from 3D CT datasets. Paired-sample Student’s t tests and intraclass correlation coefficients were performed. In addition, 2D CT and 3D IR-UTE-Cones MRI datasets were linearly registered, digitally overlaid, and compared in consensus by these two readers. Results Compared with the reference standard (3D CT), glenoid bone diameter measurements made on 2D CT and 3D IR-UTE-Cones were not significantly different for either reader whereas T1-weighted images underestimated the diameter (mean difference of 0.18 cm, p=0.003 and 0.16 cm, p=0.022 for readers 1 and 2, respectively). However, mean margin of error for measuring glenoid bone loss was small for all modalities (range 1.46-3.92%). All measured ICCs were near perfect. Digitally registered 2D CT and 3D IR-UTE-Cones MRI datasets yielded essentially perfect congruity between the two modalities. Conclusion The 3D IR-UTE-Cones MRI technique selectively visualizes lamellar bone, produces similar contrast to 2D CT imaging, and compares favorably to measurements made using 2D and 3D CT.

“…Osseous subluxation injury and morphologic changes due to osteoarthritis were evaluated. Bankart lesions were evaluated for width and percentage width loss relative to a circle fit to the inferior glenoid periphery (Fig E1 [online]) (14,15). Best-fit circle diameter was used as an additional measure for assessing agreement.…”

Purpose To determine the intermodality agreement of morphologic grading and clinically relevant quantitative measurements between computed tomography (CT) and zero echo time (ZTE) magnetic resonance (MR) imaging of the shoulder. The primary objective was to demonstrate the clinical applicability of ZTE in osseous shoulder imaging. Materials and Methods Thirty-four patients undergoing standard-of-care (SOC) MR imaging with concomitant CT were enrolled in this institutional review board-approved study. ZTE images were acquired after SOC MR imaging. Glenoid morphology (version, vault depth, erosion), injury or disease (osteoarthritis, Bankart and Hill-Sachs lesions, subchondral cysts), and evidence of prior surgery were graded or measured. κ Values, intraclass correlation coefficients (ICCs), and Bland-Altman limits of agreement were used to establish agreement. Qualitative comparison of osseous findings was performed between ZTE and SOC MR imaging. Results Binary classification and nominal/ordinal grades showed substantial or better agreement between raters and modalities (κ or ICC > 0.6). Continuous measurements exhibited strong correlation between raters and modalities, although not universally. Bankart ICCs were not significant, owing to low prevalence. ZTE exhibited greater conspicuity of enthesopathic cysts and marrow edema. In 21 of 34 cases, ZTE imaging of osseous features exceeded SOC MR imaging. Conclusion ZTE MR imaging provides "CT-like" contrast for bone. The results of this study demonstrate strong intermodality agreement between measurements and grades from CT and ZTE images in a cohort of patients undergoing imaging with both modalities. A majority of ZTE image sets provided superior visualization of osseous features when compared with SOC MR image sets. This superiority coupled with strong quantitative agreement with CT suggests that ZTE may be used clinically in lieu of CT in some cases.

“…A quantification method for anterior Bankart lesions using three-dimensional CT was described by Chuang et al and accurately predicted the need for bonegrafting in patients with osseous Bankart lesions 46 . In a head-to-head comparison between CT and MRI, the correlation between CT and arthroscopy was slightly better than that between MRI and arthroscopy for quantifying anterior glenoid bone loss 47 . However, to our knowledge, there has been no definitive work using the same radiographic methods to specifically assess and quantify posterior glenoid bone loss.…”

Glenoid Bone Loss: Assessment with MR Imaging

Abstract: MR imaging assessment of glenoid bone loss, particularly with use of glenoid width, is almost as accurate as CT assessment.
