Also known as arthrology, an arthrogram procedure is a medical imaging technique used to assess a bone fracture, a worn-down cartilage, or a ligament tear. Arthrograms are particularly useful when other imaging techniques such as X-ray fail to provide sufficient detail or pinpoint the problem. The procedure of arthrogram is a simple one wherein a dye is injected into the bones and then scanned via MRI, CT scan, or fluoroscopy. This dye helps in highlighting the mass and bones, making differentiation easier.
What Happens During the Test?
Here's a brief overview of the arthrogram procedure:
- Preparation: The patient is positioned to enable easy access to the joint under examination. The skin around the joint is cleaned and sterilised to prevent infection.
- Local Anesthesia: The area around the joint is numbed by injecting a local anesthetic.
- Contrast Injection: A needle is inserted into the joint space using fluoroscopy or ultrasound guidance. To enhance imaging, contrast material (iodine-based dye) is injected into the joint.
- Imaging: X-rays, MRI, or CT scans are taken to visualise the contrast material within the joint, providing detailed images of the joint's structures, including cartilage, ligaments, and the joint capsule.
- Post-Procedure: The needle is removed, and the injection site is cleaned and bandaged. The patient may be advised to rest the joint and avoid strenuous activities for a short period.
Arthrograms help diagnose joint abnormalities, including tears in ligaments, cartilage, or labrum. The principal role is played by the contrast material (dye) as it helps in clearly visualising joint structures, cartilages, etc.
Conclusion
Health insurance is crucial in covering the costs of an arthrogram procedure, ensuring access to diagnostic imaging that aids in accurate diagnosis and effective treatment planning.
