Mri Findings

Clearance of cervical spine (CS) precautions in the neurologically altered blunt trauma patient can be difficult. Physical examination is not reliable, and although computed tomography (CT) may reveal no evidence of fracture, it is generally believed to be an inferior modality for assessing ligamentous and cord injuries. However, magnetic resonance imaging (MRI) is expensive and may be risky in critically ill patients. Conversely, prolonged rigid collar use is associated with pressure ulceration and other complications. Multidetector CT raises the possibility of clearing CS on the basis of CT alone. We performed a retrospective review at our Level I trauma center of all blunt trauma patients with Glasgow Coma Scale Score 14 or less who underwent both CT and MRI CS with negative CT. One hundred fourteen patients met inclusion criteria, of which 23 had MRI findings. Seven (6%) of these had neurologic deficits and/or a change in management on the basis of MRI findings. Although use of the single-slice scanner was significantly associated with MRI findings (odds ratio, 2.62; P = 0.023), no significant clinical risk factors were identified. Patients with MRI findings were heterogeneous in terms of age, mechanism, and Injury Severity Score. We conclude that CS MRI continues play a vital role in the workup of neurologically altered patients.

Resonance Imaging

Due to increased use of computed tomography (CT) and ultrasonography, technological advances in equipment design, and increased availability of imaging equipment in the emergency department, imaging studies have revolutionized the assessment of the trauma patient in the past three decades. This review examines commonly used imaging modalities in trauma evaluation, initial and additional imaging, brief introduction to CT, and an overview of CT image processing and reviewing a CT scan. Head imaging, spine imaging, chest imaging, and abdominal and pelvic imaging are presented, along with injury grading, solid-organ injury appearances and specific abdominal solid-organ injuries, urinary system injury, penetrating trauma, unexplained intraperitoneal fluid, vascular injury and musculoskeletal injury. Figures show lateral view of the cervical spine; volume rendering of the pelvis; CT windows; CT imaging of acute intracranial bleeding, herniation in acute subdural hemorrhage, post-traumatic pseudoaneurysm of descending thoracic aorta, subscapular hematoma of the liver, liver laceration, pseudoaneurysm of the liver, shattered kidney and the nonperfused right kidney attributable to a traumatic renal artery injury, tigroid spleen, a focus of gas and stranding adjacent to the lateral wall of the ascending colon, extravasated urinary contrast (white material) surrounding the proximal right indicating ureteral laceration or transection, intraperitoneal bladder rupture, and contrast extravasation in the liver; magnetic resonance imaging versus CT of shear injuries; and magnetic resonance imaging in the setting of cervical spine trauma.  This review contains 18 highly rendered figures, 23 tables, and 83 references.
