You will need certain equipment to do arthrography. Here's what we use:

• anesthetic solution
  • 1% lidocaine
  • sodium bicarbonate solution to buffer the lidocaine (about 0.5 ml added to 10 ml of lidocaine is common).
• contrast solution
  • gadolinium solution
  • 1% lidocaine
  • iodine-based contrast
• needles
  • needles of various sizes for preparing local anesthesia and contrast solutions and for accessing the joint
• syringes
  • 1 ml and 20 ml for preparing contrast solution
  • 10 ml for preparing local anesthetic solution
• sterile tubing to connect contrast syringe to needle
• sterile towels or drapes for preparing a clean work area
• local antiseptic solution (we currently use Chlora-prep sticks)
