Objective:
Staging of bronchial carcinoma presents a diagnostic challenge. In addition to CT scans, endobronchial ultrasound is used. The aim of this study was to compare the diagnostic accuracy of high-resolution multidetector CT (MSCT) with that of endobronchial ultrasound with respect of detection and extension of the bronchial lesions.
Methods:
24 patients with lesions in the central bronchial area were examined using both EBUS and MSCT. Multiplanar reconstructions (MPR) as well as virtual endoscopy (VE) were used as adjuncts in this investigation of the comparative diagnostic accuracy of MSCT and EBUS in the imaging of bronchial lesions.
Results:
No significant difference could be established between EBUS and MSCT in detecting and extension of bronchial lesions. With both procedures, the use of supplementary techniques may be advantageous and helpful in individual cases.
Conclusions:
When compared with EBUS, MSCT with post-processing has equally high sensitivity with regard to the visualization of malign endobronchial lesions.

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...

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...
