Achilles tendon: MR imaging at 1.5 T

Area of Science:

• Orthopedic imaging
• Musculoskeletal radiology
• Sports medicine imaging

Background:

• Achilles tendon injuries are common in athletes and can significantly impact mobility.
• Accurate diagnosis of Achilles tendon abnormalities is crucial for effective management.
• Magnetic resonance (MR) imaging offers detailed visualization of soft tissues.

Purpose of the Study:

• To evaluate the utility of 1.5 T magnetic resonance (MR) imaging in assessing Achilles tendon pathology.
• To correlate MR imaging findings with the degree of Achilles tendon continuity.
• To explore the role of MR imaging in guiding diagnosis, treatment, and rehabilitation of Achilles tendon injuries.

Main Methods:

• Thirty Achilles tendon examinations were performed using 1.5 T MR imaging.
• Twenty examinations were from patients without suspected abnormalities, and ten were from patients with suspected abnormalities.
• MR imaging findings were analyzed for signal intensity, tendon morphology, and continuity.

Main Results:

• Normal Achilles tendons appeared hypointense and flattened on MR images.
• Partial tears showed high-signal intratendinous collections.
• Complete ruptures presented as tendinous discontinuity, while surgical repairs displayed inhomogeneous signals.
• Chronic tendinitis was characterized by diffuse tendon thickening.
• MR imaging successfully determined the degree of tendinous continuity in all cases.

Conclusions:

• 1.5 T MR imaging is a valuable tool for diagnosing Achilles tendon abnormalities.
• The technique accurately assesses tendon continuity, crucial for differentiating tears and evaluating surgical repairs.
• MR imaging findings can inform treatment decisions and guide the pacing of rehabilitation for Achilles tendon injuries.
