Understanding Cervical Spine X-Ray Alignment

Sal Khan introduces Dr. Mahadevan from Stanford University. They discuss the importance of X-ray adequacy and alignment for diagnosing spinal issues.

Dr. Mahadevan explains the four alignment lines: anterior vertebral body line (AVBL), posterior vertebral body line (PVBL), spinolaminar line, and the line through the tips of the spinous processes.

Sal learns how to identify misalignments. They discuss the significance of detecting even slight deviations for preventing spinal cord damage.

Sal applies his newly learned skills by examining actual X-rays, identifying misalignments, and discussing their implications with Dr. Mahadevan.

They conclude by emphasizing the use of advanced imaging techniques like CT scans for detailed analysis when X-rays show any irregularities.
