Importance of MRI Cervical Extension Flexion
Dynamic MRI plays an essential role in diagnosing movement-related spinal disorders. When the neck flexes or extends, the cervical vertebrae shift slightly. In individuals with disc herniation, ligament laxity, or prior spine surgery, these shifts can cause compression on the spinal cord or nerve roots, producing symptoms that a conventional neutral-position MRI might miss.
Doctors recommend this test for patients experiencing:
-
Neck stiffness or limited range of motion
-
Symptoms worsening when moving the neck
-
Suspected spinal instability after trauma or surgery
-
Chronic numbness or weakness in arms or hands
-
Cervical spondylotic myelopathy
MRI Cervical Extension Flexion helps clinicians make accurate diagnoses, plan surgeries, and monitor post-treatment outcomes. It ensures subtle motion-induced spinal problems are not overlooked.
Benefits of Cervical Spine Flexion Extension MRI
-
Detects motion-dependent spinal cord compression that static scans can miss
-
Provides a better understanding of cervical disc and ligament movement
-
Helps in diagnosing early cervical myelopathy or instability
-
Safe, non-invasive, and does not use ionizing radiation
-
Valuable for preoperative assessment and postoperative evaluation
-
Aids in personalized treatment planning for spine and neurological conditions
This technique is especially beneficial for orthopedic surgeons, neurologists, and rehabilitation specialists managing neck movement disorders.
How MRI Cervical Flexion and Extension is Performed
The procedure takes approximately 30–45 minutes. The patient is asked to lie still on an MRI table that slides into the scanner. During the test:
-
The radiologist positions the patient’s neck in a neutral position first.
-
The scan is repeated while the patient’s neck is gently bent forward (flexion).
-
A final scan is taken while the neck is extended backward.
No contrast dye is typically required unless the doctor suspects infection, inflammation, or tumor. The test is painless, though patients may feel mild strain when holding specific neck postures briefly. After imaging, a radiologist interprets the results, comparing flexion and extension images to identify abnormalities.
MRI Cervical Spine – Flexion Extension Parameters
Common imaging parameters used in MRI Cervical Flexion-Extension studies include:
-
T1-weighted, T2-weighted, and STIR sequences
-
Slice thickness: 3–4 mm
-
Planes: Sagittal and axial
-
Field of view: 24–28 cm
-
No intravenous contrast (unless clinically indicated)
-
Dynamic positions: Neutral, Flexion, Extension
These parameters allow accurate comparison of spinal cord and disc alignment changes between positions.
