Purpose of Examination

Ultrasound, by using the difference in breast tissue density, converts the depth of echo waves into the image of tissues to distinguish whether there is any abnormality in the chest.

The advantiges of this examination include easily operation, rapidity, noninvasiveness, and no radiation exposure, Ultrasound is a safe examination that provides images quickly.

Indications

• Parenchymal lung lesions: pulmonary collapse or obstructive pneumonia which are caused by a tumor blocks the airway
• Pericardial lesions: pericardial effusion, neoplasms, etc.
• Neck lymphatic metastasis.

Examination and Therapy Programs

• Chest ultrasound imaging.
• Ultrasound-guided fine needle aspiration.
• Ultrasound-guided biopsy of thoracic or pleural lesions.
• Ultrasound guided pleural effusion drainage or chest tube insertion and drainage.
