Nontraumatic Emergent Neuroradiology: Review and Self-Assessment Module

Yoshimi Anzai1 and Basavaraj Ghodke2

1 Department of Radiology, Division of Neuroradiology, University of Washington, 1959 NE Pacific St., NW 011, Box 357115, Seattle, WA 98195-7115.
2 Department of Radiology, Harborview Medical Center, Seattle, WA.

Objective

The educational objectives for this case-based self-assessment module on imaging of nontraumatic emergent neuroradiology are to use case examples to teach the imaging features of CT and MRI of emergent neuroradiologic diagnoses and to improve the reader's understanding of the pathophysiology and clinical management of each clinical scenario. Imaging plays a critical role in assessing patients with acute neurologic symptoms. CT is quick and easy to perform in an emergency setting and is often the technique of choice for any neurologic emergency situations. Clinical correlation is crucial for accurate diagnosis and triaging patients for further evaluation. Persistent or progressive neurologic symptoms despite negative CT should prompt other imaging studies.

Conclusion

At the end of this self-assessment module, readers will be able to generate a concise list of differential diagnoses for imaging findings that often are encountered in patients with nontraumatic neurologic emergency.

Keywords: brain imaging • case-based learning • emergency • neuroradiology • self-assessment
