Abstract:
Endoscopic ultrasound-guided fine-needle aspiration has significantly increased the capacity of pulmonary diagnostic procedures. Since this method was introduced, 1212 examinations have been performed at two centres of pulmonary medicine. Data on indications, procedures, findings, diagnostic yield and complications have been recorded. This paper describes the experiences thus gained regarding the possibilities and limitations of the method and assesses the current significance of the technique in pulmonary medicine according to previous studies. In primary diagnosis of mediastinal tissue alterations and in staging of malignant diseases the method offers a low-complication diagnostic measure which has a seminal impact on therapy in many cases, even though in daily practise the diagnostic accuracy of published studies is not always attained.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
