Arthrogram & MR Arthrogram at Evolution Imaging

An arthrogram is a specialized imaging procedure used to visualize the inside of a joint with enhanced clarity. It involves the injection of a contrast material—commonly referred to as “dye”—directly into the joint space. This contrast helps highlight structures that may not be visible on a standard X-ray, including cartilage, ligaments, tendons, and the joint capsule.

This diagnostic tool is especially helpful when standard imaging does not provide enough information about the cause of joint pain or limited motion.

Why Arthrograms Are Performed

Arthrograms help diagnose unexplained joint pain or dysfunction by clearly showing soft tissue structures. They are commonly used to evaluate:

  • Tears in ligaments, tendons, or cartilage

  • Abnormalities of the joint capsule

  • Loose bodies within the joint

  • Cysts or abnormal growths

  • Post-surgical evaluations

  • Guided needle placement for joint injections

How it Works

1. Contrast Injection
A radiologist will inject contrast material directly into the joint using a thin needle, often guided by fluoroscopy or ultrasound. In some cases, a local anesthetic is applied to numb the area. If excess joint fluid is present, it may be removed before the contrast is introduced.

2. Imaging the Joint
Once the contrast is injected and distributed, a series of images is taken using one or more of the following imaging techniques:

  • X-ray – Shows joint outlines enhanced by the contrast.

  • Fluoroscopy – Offers real-time, moving X-ray images.

  • MRI (Magnetic Resonance Imaging) – Offers high-resolution images of soft tissue.

Types of Arthrograms

  • Uses X-rays or fluoroscopy with an iodine-based contrast.

  • Uses a gadolinium-based contrast and MRI to provide detailed soft tissue images.

    • Direct Arthrography: Contrast is injected directly into the joint.

    • Indirect Arthrography: Contrast is injected into the bloodstream and absorbed into the joint (less common).

What to Expect After the Procedure

After your arthrogram, you may be advised to rest the joint for 12–24 hours. Mild discomfort such as swelling, pain, or a feeling of fullness is normal and can usually be relieved with ice packs and over-the-counter pain medication.

Contact your physician if you experience:

  • Persistent or worsening pain

  • Swelling, redness, or warmth

  • Fever

MR Arthrography: Enhanced Imaging

When combined with MRI, the procedure becomes MR Arthrography, a powerful tool for detecting subtle joint abnormalities. The gadolinium contrast coats soft tissue structures inside the joint, improving their visibility on MRI.

Benefits of MR Arthrography include:

  • Clear visualization of small tears and detachments

  • Better outline of cartilage surfaces and irregularities

  • Detection of loose bodies within the joint

  • Detailed assessment of postoperative changes
