Abstract:
The past decade has witnessed the application of many advanced bronchoscopic modalities to improve access to the solitary pulmonary nodule (SPN). Although many of the techniques are applied on a regular basis by bronchoscopists, which technique-or which combination of techniques-will offer the best performance and cost-effectiveness remains to be determined. The authors anticipate that bronchoscopic approaches to the SPN will continue to proliferate as technologic advances and clinical data accumulate. Research should focus on combinations of techniques, cost-effectiveness, and incorporation of these tools in diagnostic algorithms for lung nodules/masses.

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...

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
