Radiology at the Orthopaedic Institute

Our Services

The innovative techniques and technologies available at the Orthopaedic Institute include:

• High-field, high-resolution MRI operating at 3 Tesla used for joint and spine disorders, bone and soft tissue disorders, and rheumatologic diseases. High-resolution MRI at 3 Tesla (the highest-strength magnetic field available for medical practice) allows better detection of abnormalities than standard MRI.
• MR arthrography for better evaluation of shoulder, wrist, elbow and hip joints to find the cause of pain and limited function. This technique (in which we inject the joint with a material that enhances imaging) improves analysis of cartilage.
• MRI techniques to analyze cartilage quality before cartilage is lost, which allows us to assess the risk for osteoarthritis.
• Metal-suppression techniques that allow us to use MRI with patients who have joint replacements, implants and other hardware.
• MR technologies to suppress motion in patients with pain or claustrophobia, allowing us to obtain better-quality images.
• Joint injection for osteoarthritis pain treatment including local anesthetics, corticosteroids and viscosupplements such as hyaluronate and Synvisc (materials similar to joints’ natural lubrication fluid).
• Bone mineral density measurements using dual energy X-ray absorptiometry.
• Tomosynthesis (a technique that allows precise evaluation without increased radiation) for better detection of fractures and fracture healing.

MRI and Claustrophobia

While open scanners are helpful for patients with claustrophobia, their image quality is generally worse than that produced by our 3 Tesla scanner. Poor image quality may limit what we can learn from the images.

Keep in mind that:

• Our MRI is shorter, wider and better lit as compared to other MRI machines.
• Our staff understands claustrophobia.
• Imaging of the lower extremities – foot, knee and leg exams – do not require entering the tube completely. Only the leg is in the tube.
• Imaging of the shoulders or spine requires entering the tube, and sedation should be considered. After receiving a sedative, you should not drive a car or operate machinery.
• Our motion-correction imaging allows for shorter exam times and less time spent in the scanner.
