“…Other studies have shown high correlations between MRI and CT measurements, 42 89% of values within 1 standard deviation of each other, 35 and all values within 2 standard deviations of one another. 43 Recently several authors have investigated comparisons between 3-dimensional CT and 3-dimensional MRI with promising results, although these sequences are not yet widely available. 31,34,36 Despite the numerous previous studies conducted, the treatment implications of 3.4% difference 41 or 1 standard deviation, 35 are unclear.…”

“…However, several authors are making an attempt to replace CT with MRI in order to reduce cost for imaging studies and avoid possible radiation exposure. [13,14,15,16] Owens and co-workers proposed a unique method of obviating use of CT using MRI. [15] The role of preoperative imaging study is, first of all, to assess the glenoid shape and morphology in shoulders with recurrent anterior instability in addition to quantifying glenoid bone loss [5] .…”

BACKGROUND Glenoid track is a new classification system developed to biomechanically quantify the effects of a combined glenoid and humeral head bony defects on instability that can be utilized to assess the risk of engagement of a Hill-Sachs lesion in a patient with anterior shoulder instability. The aim of the study is to evaluate the humeral head engagement on the glenoid by utilizing glenoid track method and to compare the results with the arthroscopic findings. METHODS We performed a prospective study of 31 patients with recurrent shoulder dislocation over a period of two years. A 64 slice CT scanner was used. Using post processing technique, the glenoid track was calculated to classify the shoulders as on-track or off-track. RESULTS The glenoid track and concurrent Hill Sachs interval were calculated into 4 entities-"Off-track" lesion with <25% glenoid bone loss [41. 94%], > 25% bone loss [6. 45%], "On-track" lesion with <25% glenoid bone loss [51. 61%] and >25% glenoid bone loss [0]. CONCLUSIONS The glenoid track concept postulated that a Hill-Sachs lesion outside this track was at a high risk for engagement and thus recurrent instability. CT measurement as a predictor of off-track and on-track lesion, using the differences between Hill-Sachs and glenoid track had a p value of 0.0001. The glenoid track concept is important to assess the overall risk for engagement prior to surgery and help in guiding surgical decision making such as bony augmentation procedure.

“…Some studies have suggested that quantitative measurements made on conventional MRI sequences are similar to those made on CT [16–19], whereas others have shown a higher performance of CT [4, 20, 21]. More recently, 3D MRI sequences were implemented with a Dixon fat-suppression technique which enabled soft tissue subtraction and increased contrast from lamellar bone [22–24].…”

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.
