This review tried to cover the definition, current status, clinical significance, indications, contraindications, ultrasound evaluation, as well as preparations, steps, molecular diagnosis, cytology diagnosis, and possible pitfalls of this technique. Our purpose is trying to make this procedure universalized and standardized in order to serve more patients by providing clinicians with some helpful references and advices.
