Purpose

To demonstrate the clinical utility of Angiography CT (ACT) for the evaluation of the bony cervical spine in the trauma patient.

Methods & Materials

ACT scans of the cervical spine were acquired in multi-trauma patients undergoing emergent cerebral/cervical angiography using rotational angiography sequences with or without contrast. Post processing and review of the cervical spine in standard orthogonal planes was performed on a 3D workstation. Comparison was made with conventional CT including sagittal and coronal reconstructions.

Results

ACT demonstrates fractures of the cervical spine equal to that of conventional CT. Although the evaluation of the soft tissues is limited, the ability of ACT to be acquired during angiography may obviate the need for conventional CT in patients with multiple traumatic injuries who require emergent angiography.

Conclusion

ACT provides a fast, accurate and novel way to assess bony cervical spine pathology in a multi-traumatic patient and may preclude the need for conventional CT in certain clinical situations.
