Comparative StudyRole of multidetector computed tomography in the assessment of cervical spine trauma.
Clearing the cervical spine has relied on individual and center-based experience. Not long ago, the screening modality of choice was radiography. ⋯ Furthermore, clinical criteria have been validated to assess for cervical spine injuries and determine the need for imaging evaluation based on patient risk. Once imaging is deemed necessary to exclude cervical spine injury based on clinical predictors, multidetector computed tomography becomes the accepted modality of choice, providing accurate and rapid assessment and improving the understanding of injury patterns and stability determinants.

Screening multidetector computed tomography angiography in the evaluation on blunt neck injuries: an evidence-based approach.
Blunt cerebrovascular injuries (BCVI) can cause ischemic stroke and are associated with high mortality rates. These injuries may have an initial silent course and if recognized in a timely fashion can be treated before neurologic deficit occurs. ⋯ However, in recent years, there has been a renewed interest in the use of noninvasive techniques, such as multidetector computed tomography angiography (MDCTA) for the evaluation of these patients. The accuracy of MDCTA with respect to digital subtraction angiography is not completely elucidated; however, MDCTA shows a level of accuracy sufficient to serve as an initial screening examination for blunt cerebrovascular injuries.

Kinematic cervical spine magnetic resonance imaging in low-impact trauma assessment.
Kinematic magnetic resonance imaging can be implemented as a noninvasive adjunct examination for injuries in the cervical spine in the clinical assessment of ligamentous, disk, and soft-tissue injuries, as a basis for determining medical vs. surgical management, and in establishing the degree of functional clinical impairment. This article discusses the clinical indications and application of kinematic cervical spine magnetic resonance imaging method in the diagnosis and management of cervical spine injuries. The spectrum and grading classification of cervical spine injuries using kinematic magnetic resonance imaging is also discussed.

Multidetector row computed tomography in the management of penetrating neck injuries.
Penetrating neck trauma may occur from gun shots, stabbings, and accidental injury. Approximately 50% of gunshot and 10%-20% of stab-wound patients are reported as having severe injuries and the mortality from severe vascular injuries is reported as high as 50%. ⋯ Experience with interpreting and reconstructing computed tomography images, understanding the clinically important findings, and avoiding pitfalls is critical for successful patient care. Therefore, radiologists and clinicians who treat trauma patients need to familiarize themselves with the computed tomography angiography technique and appearances of vascular injury and know when to recommend further evaluation, such as interventional angiography or open surgery.

Multidetector row computed tomography of the injured larynx after trauma.
Laryngeal trauma is rare and can occur as an isolated injury or as part of multitrauma. On the basis of airway patency, it is decided whether the patient needs rapid surgical intervention or whether the patient would profit from preoperative imaging done with multidetector row multislice thin section computed tomography with multiplanar reconstruction in the soft-tissue and bone window setting. Grading the fracture pattern from minor isolated to multiple dislocated fracture lines helps to plan individual treatment options and to prevent long-term voice complications.
