Comparison of MRI FRACTURE sequence and CT for three-dimensional bone imaging in patients with shoulder dislocation

Motivation: It is highly desirable to evaluate both soft tissue and bone in a single examination. FRACTURE could be used as a viable auxiliary method of conventional MRI to allow evaluating soft tissue injury and quantifying bone defect simultaneously. Goal(s): To evaluate the equivalence of FRACTURE and 3D-CT in quantifying bone loss in patients with shoulder dislocation and measuring the morphological parameters of the shoulder. Approach: Fifty-six patients with shoulder dislocation underwent both MRI (including FRACTURE) and CT scanning. Paired t-test was utilized to assess the difference between them. Results: There was no statistical difference between the measurements of 3D-CT and FRACTURE. Impact: FRACTURE, a radiation-free and reliable examination, could serve as an effective auxiliary method to conventional MRI. It allows for simultaneous evaluation of soft tissue injury and accurate quantification of bone defect.
