Toward More Useful Pressure-Controlled Discography: In Vitro Evaluation of Injection Speed, Sensor Location, and Tube Length

Abstract

Discography can be better performed with low speed injection (≤0.01 cc/second), using an extrasyringeal sensor. Difference of length of connecting tubings did not cause significant pressure differences. These data suggest that automated discography is a helpful adjunct to improve diagnostic accuracy, due to extrasyringeal location of pressure sensor and greater control of injection speed.
