Direct coronal computed tomography of the upper cervical spine

Area of Science:

• Radiology
• Medical Imaging
• Orthopedic Surgery

Background:

• Conventional tomography is the standard for evaluating upper cervical spine lesions, including the odontoid peg.
• Direct coronal computed tomography for cervical spine imaging has not been previously documented.

Purpose of the Study:

• To introduce and demonstrate the utility of direct coronal computed tomography for upper cervical spine imaging.
• To compare orbital radiation dosage between the new technique and conventional tomography.

Main Methods:

• Direct coronal computed tomography images of the upper cervical spine were acquired using a removable head support.
• Gantry tilt was adjusted from the scanogram.
• Orbital radiation doses were compared using thermoluminescent dosemeter chips on a phantom.

Main Results:

• Direct coronal computed tomography provided superior visualization of skeletal features in the upper cervical spine.
• Orbital radiation dose was negligible compared to conventional tomography.

Conclusions:

• The described technique offers enhanced imaging of the upper cervical spine.
• Direct coronal computed tomography may serve as a replacement for conventional tomography in assessing stable upper cervical spine lesions.
