Overview

Bacterial pneumonia is primarily diagnosed with chest x-ray and CT scan in certain cases. Other diagnostic tests are available but are frequently not utilized compared to the aforementioned two modalities. These include ultrasonography, chest MRI, and needle biopsy of the affected lung. Bronchopsy may also be used to diagnose pneumonia.

Lung Ultrasound

Ultrasonography is very useful in assessing the pleural fluid including its amount, viscosity and loculations as well as pulmonary septations. It can be helpful in cases of complex pleural collections. Results of ultrasonography rely upon the homogeneity, shape, marginal characteristics as well as presence or absence of air bronchograms. Pneumonia progresses to hepatization in which it appears liver-like on imaging, with the exception of branching structures naturally present within the lungs.
