To evaluate and compare the glenoid track method in 3D-reconstructed computed tomography (3D-CT) scans with magnetic resonance imaging (MRI) and/or arthro-MRI. Forty-four shoulders with clinical and radiographic diagnosis of traumatic anterior instability were assessed using 3D-CT, MRI, and/or arthro-MRI scans. Glenoid track (GT), Hill-Sachs interval (HSI), and glenoid bone loss (GBL) were determined by a radiologist using 3D-CT images, and classified as on-track/off-track.

Methods: This study retrospectively evaluated 53 shoulder radiographs and MRI/MRA to compare the measurements of HSL through Hardy's radiographic method. Imaging exams used in the study were conducted between the March 2013 AND September 2015.
Objective: To demonstrate the relationship between the size, degree of retraction and topography of rotator cuff injuries and the degree of rise of the humeral head, and to evaluate the influence of gravity, using magnetic resonance imaging (MRI).
Methods: We evaluated 181 shoulder MRIs from 160 patients aged over 45 years, between November 2013 and July 2014. The patients were divided into two groups: one control (no lesion or partial damage to the rotator cuff); and the other with complete tears of the rotator cuff.
Objective: Radiologists should be familiar with MRI findings suggestive of spondyloarthritis and its differential diagnosis. Because most publications describing these features are found in the rheumatologic literature, the purpose of this review is to present these imaging findings of axial spondyloarthritis to radiologists.
Conclusion: New imaging outcomes have improved the diagnosis and follow-up of spondyloarthritis and the assessment of therapeutic modalities.
Purpose: To evaluate the imaging findings of patients with clinical symptoms of lower back pain who underwent magnetic resonance imaging (MRI) of the lumbar spine with axial loading.
Materials And Methods: We examined 120 patients by MRI, before and after axial loading, using a compression device that applied 50% of their body weight for a load time of 5min. The dural sac cross area (DSCA) was examined by two experienced radiologists before and after axial load, and their findings were compared.
