Recommended MRI Cervical Spine Protocols and Planning

MRI Cervical Spine localiser

A three-plane localizer must be taken at the beginning to localize and plan the sequences. Localizers are normally less than 25 seconds, and they consist of T1-weighted low-resolution scans.

T2 tse sagittal 3mm

Plan the sagittal slices on the coronal plane; angle the positioning block parallel to the spinal cord. Check the positioning block in the other two planes. An appropriate angle must be given in the axial plane (parallel to the line along the center of the vertebral body through the length of the spinous process). Check the positioning block in the sagittal plane; the field of view (FOV) must be big enough to cover the entire cervical spine from the pons down to T3 (normally 260mm). The slices must be sufficient to cover the spine from the lateral border of the right transverse process to the lateral border of the left transverse process. A saturation band must be placed over the neck (in front of the esophagus) in the sagittal plane. This is to avoid swallowing and pulsation artifacts over the spinal area. The phase direction should be head to foot to avoid motion artifacts from the neck.

T2 TSE Axial 3mm

Plan the axial slices on the sagittal plane and angle the position block perpendicular to the spinal cord. Additional blocks must be placed if there is a disc prolapse at any other level (e.g., T2, T3).. An appropriate angle must be given in the coronal plane, parallel to the intervertebral disc space. The slices should be sufficient to cover the entire C spine from C2 to T1. A saturation band must be placed over the neck (in front of the esophagus) in the sagittal plane. This is done to avoid swallowing and vascular pulsation artifacts over the spinal area.

Indications For contrast enhanced cervical spine scan

Use T1 TSE fat-saturated axial and sagittal sequences after the administration of IV gadolinium DTPA injection (copy the planning outlined above). The document below provides access to the recommended dosage of gadolinium DTPA injection, as advised by the manufacturer.

Additional sequences for spinal AVM and lesions obscured by CSF flow.

T2 SPACE 3D sagittal 0.7 mm isotropic

Plan the sagittal 3D block on the coronal localizer, angling the positioning block parallel to the spinal cord. Verify the positioning block in the other two planes. In the axial plane, ensure the block is angled appropriately, parallel to the line running through the center of the vertebral body along the length of the spinous process. Check the positioning block in the sagittal plane to ensure the field of view (FOV) is large enough to cover the entire cervical spine, from the pons down to T2 (typically 250mm). The slices should sufficiently cover the spine from the lateral border of the right transverse process to the lateral border of the left transverse process. Place a saturation band over the neck (in front of the esophagus) in the sagittal plane to avoid swallowing and pulsation artifacts over the spinal area. The phase direction should be head to foot to prevent motion artifacts from the neck.
