CT & MRI Arthrogram

An Arthrogram is a type of CT or MRI, where a contrast agent is injected directly into a joint before the area is scanned (shoulder, knee, wrist, ankle, etc) so that a more comprehensive image and accurate diagnosis of the soft tissue injury can be determined. This dye outlines cartilage, ligaments, labrum and joint spaces.

Your GP or Specialist may request this in addition to a general CT or MRI to identify ligament tears (labral tears or rotator cuff tears), meniscal injuries or cartilage defects.

Arthogram is considered a safe procedure, however with any injection there can be some risks involved. These are rare, but include:

  • Bruising or swelling at the injection site

  • Localized infection at the injection site

  • Temporary discomfort

  • Allergic reaction to medication

Contact your GP immediately if you experience any of the following:

  • Fever, chills or generally unwell in the days following the injection

  • Redness, pain or swelling at the injection site

  • A significant increase of pain in the area following the injection
