Purpose: To evaluate the magnetic resonance imaging (MRI) findings to improve the diagnostic accuracy for transverse process fractures and sacral fractures. Materials and Methods: The lumbosacral MRI scans of 214 patients (mean age, 60 years; male-to-female ratio, 85:129), who had spine trauma between January and November 2015 were included. Two radiologists evaluated the presence, number, level, and anatomic site of the fractures on MRI with computed tomography as reference standard. Imaging findings were described as cortical disruption, marrow edema, or soft tissue edema on T1-, T2-, and fat-suppressed T2-weighted images. A statistical analysis was performed to compare the diagnostic accuracy of the MRI pulse sequences for the transverse process and sacral fractures. Results: Of 168 fractures, 26 (15.5%) and 13 (4.9%) were in the transverse processes and sacra, respectively. A paravertebral soft tissue edema occurred in the transverse process fractures (80.8%) and presacral soft tissue and marrow edemas occurred in the sacral fractures (46.1%). The sensitivity for the transverse process fractures was 88% on the T2-weighted image. It was 92% on fat-suppressed T2- and T1-weighted images for sacral fractures. Conclusion: Bone marrow and soft tissue edemas on the MRI could potentially improve the diagnostic accuracy of an MRI for fractures in the transverse process and sacrum. [ABSTRACT FROM AUTHOR] |
