Recent studies have confirmed that US is a very useful diagnostic tool for various diseases of the chest. The image information provided by US is helpful for etiologic diagnosis and clinical management. US-guided needle biopsy provides a precise and safe approach for transthoracic tissue sampling of lesions. ⋯ Color Doppler US and amplitude US angiography further extend the diagnostic potential and safety of this invasive procedure. Vascular information can be obtained and the needle shaft can be visualized clearly while conducting a biopsy. US examination and US-guided needle aspiration biopsy have now become indispensable diagnostic tools for various chest diseases.

ReviewImage-guided management of complicated pleural fluid collections.
Percutaneous image-guided catheter drainage with adjunctive ICFT has become the mainstay in the treatment of complicated pleural fluid collections. There are six basic principles of image-guided drainage and ICFT that must be understood to maximize the efficacy and safety of the procedure. 1. There must be a basic understanding of why traditional nonguided thoracostomy drainage fails in a significant percentage of patients. ⋯ Effective closed drainage carries lower morbidity, mortality, and cost than does open surgical drainage. For radiologists and clinicians alike it does not suffice simply to place one or more thoracostomy tubes, round daily, and hope that the occasional use of fibrinolytic agents does the rest. Without a more aggressive approach to catheter position and management the efficacy is no greater than that historically seen with nonguided closed drainage and surgeons will continue to plead for earlier effective open drainage.
