Background
The purpose of this educational exhibit is to review the role of ultrasound and MRI in the evaluation of traumatic and non-traumatic Achilles tendon pathology and to provide a pictorial review of the characteristic findings.

Educational Goals / Teaching Points
- Review important anatomic considerations when reviewing the Achilles tendon - Discuss risk factors for and the appearance of Achilles tendinopathy - Discuss the classification of Achilles tendon injuries by anatomical area - Differentiate between commonly seen entities such as retrocalcaneal bursitis, retroAchilles bursitis, Achilles paratenonitis and Achilles paratendinitis - Review the role of ultrasound and MRI in the diagnosis of Achilles tendon pathology

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
- Achilles tendon rupture - Non-insertional Achilles tendinosis - Insertional Achilles tendinosis - Achilles paratendinitis - Adhesive tendinopathy - Retrocalcaneal bursitis - Achilles tendo-fasciitis - Ultrasound-Guided percutaneous interventions - Dynamic ultrasound - Magnetic Resonance Imaging

Conclusion
Achilles tendon pathology is a common source of morbidity in athletes and the general population and as a result, musculoskeletal radiologists must be familiar with the anatomy and pathology of the tendon. This exhibit reviews the relevant anatomy, the imaging features and classification system of the common classes of injuries encountered. Ultrasound and MRI are compared with regards to diagnosis and staging of injury.
