Asymmetry of the Odontoid Lateral Mass Interval in Pediatric Trauma CT: Do We Need to Investigate Further?

Ayelet Eran

Ayelet Eran

This project was conducted during my fellowship at Hopkins under the supervision of Drs. Izbudak and Yousem. We sought to find parameters that would differentiate injured and noninjured children who sustain cervical spine trauma and have asymmetry of the odontoid lateral mass intervals. We encountered this problem frequently during routine CT work in a busy trauma center. Had we opted to send … more »

Spinal Cord Injury after Blunt Cervical Spine Trauma: Correlation of Soft-Tissue Damage and Extension of Lesion

Rafael Martínez-Pérez

Rafael Martínez-Pérez

MRI sequences are constantly evolving, and new techniques enable not only improved diagnostic but also prognostic information. The ability of MRI to predict outcomes in cervical spine trauma has, however, been relatively limited to the detection of cord compression, edema, and intramedullary hematoma. Our group believes that these factors explain only part of the pathologic process determining the ultimate neurologic outcome. … more »

Evaluation of the Intervertebral Disc Angle for the Assessment of Anterior Cervical Discoligamentous Injury

Saeed Fakhran

Saeed Fakhran

The evaluation of patients following cervical spine trauma is an integral part of any busy neuroradiology practice. CT is usually the first imaging modality obtained in these patients, having long supplanted plain film imaging. While CT is known to provide exquisite detail of the bony anatomy of the cervical spine and is an excellent tool to exclude acute bony injury, patients … more »

Tectorial Membrane Injury: Frequently Overlooked in Pediatric Traumatic Head Injury

Thierry A.G.M. Huisman

Thierry A.G.M. Huisman

We chose to retrospectively review the neuroimaging findings in pediatric tectorial membrane injuries/retroclival hemorrhages (REH) to better understand the incidence and mechanisms of injury that may lead to these findings. In addition, and maybe foremost, we aimed to alert the readership about the importance of actively reviewing this area carefully in the pediatric population. The cranio-cervical junction is at increased … more »

Reliability of the STIR Sequence for Acute Type II Odontoid Fractures

Forrest Lensing

Forrest Lensing

As the use of MR imaging in the emergency department increases, it has become increasingly important to recognize the pitfalls associated with MR imaging in the acute setting. We arrived at our research topic after seeing several elderly patients imaged acutely with MRI of the cervical spine. These patients had little or no bone marrow edema on STIR imaging despite the … more »

Screening Cervical Spine CT in the Emergency Department, Phase 2: A Prospective Assessment of Use

Brent Griffith

Brent Griffith

This study was the second phase of a collaborative effort between the departments of radiology and emergency medicine, aiming to evaluate and address potentially inappropriate utilization of screening cervical spine CT in the emergency department.

Blunt trauma with potential cervical spine injury is a common reason for presentation to emergency departments. Because failure to diagnose injury of the cervical spine can have disastrous … more »

Marrow Edema Variability in Acute Spine Fractures

Mark Brinckman

Mark Brinckman

We chose to investigate the utility of marrow edema in the setting of acute fractures when we began to recognize some patients at our institution had known acute spine fractures on routine CT imaging, but when subsequently imaged by MRI, they lacked the presence of marrow edema. In an attempt to understand this phenomenon better, we developed a hypothesis that marrow … more »
