Musculoskeletal Ultrasonography (US) has unique advantages such as excellent spatial resolution for superficial structures, dynamic capability, direct correlation and provocation of the symptom. In this regard, US is increasingly used to evaluate problems in small joints such as foot and ankle. However, it is almost impossible to evaluate every single anatomic structure within a limited time.Therefore, US examination can be a faster and more efficient one when the radiologists know where to look and image the patient with typical symptoms. In this review, common etiologies of heel pain will be discussed in a problem-based manner. Knowing the common pain sources and being familiar with their US findings will help the radiologist to perform an accurate and effective US examination.
