Q

CT Scan

A

(Computed Tomography) is a special type of X-Ray machine. Rather than a single X-Ray (traditional X-Ray), several beans are send simultaneously from different angles.

  • Far more detailed
  • Images from two-dimensional scans can be reconstructed into 3-D images.

Q

Dallas Grading System

A

A system designed to grade the severity of annular disruption on a scale of 0-5. Grade 0 is for normal discs, and Grade 5 represents a tear involving full thickness of the annulus with extra-annular leakage.

A visual analog scale to assess pain in pediatric patients. Doctor explains that each face shows how a person in pain is feeling - Face 0 - very happy because s/he does not hurt at all - Face 1 - hurts just a little bit - Face 2 - hurts a little more - Face 3 - hurts even more - Face 4 - hurts a whole lot - Face 5 - hurts as much as you can imagine (although do not need to be crying to hurt this bad)
