Magnetic Resonance Imaging of the Achilles Tendon
Several different clinical scenarios warrant evaluation of the Achilles tendon with magnetic resonance imaging (MRI). However, the main reasons to image the Achilles are pain, trauma, infection, or a mass. Less commonly, an MRI may be used to screen for hypercholesterolemia. Although a diagnosis of Achilles tendon rupture is usually evident clinically, the gap between the ruptured ends of the tendon may be difficult to ascertain by physical examination alone. This gap is frequently used to determine which technique will be employed for surgical repair. When the gap is small, and the injury acute, then nonoperative management may be selected (see Chapter 5). In the chronic rupture, when the gap is less than 6 cm, the augmentation techniques can be applied and when the gap is greater than 6 cm, then tendon transfer is selected. It is often useful for the surgeon to know which technique will be best utilized for preoperative planning, and in these situations MRI can...
