bronchopneumonia on CXR

Diffuse and patchy

Lobar pneumonia is usually caused by:

Streptococcus pneumonia

Phases of lobar pneumonia

congestion, red hepatization, gray hepatization, resolution

Lobar pneumonia on chest x-ray

bronchopneumonia refers to

focal/patchy areas of consolidated acute suppurative inflammation in one or more lobes. Usually, it involves lower lobes (basal) bilaterally.

Hemothorax

blood in the pleural cavity

Pneumothorax CXR findings

-Hyper-translucent (black) area at site of pneumothorax
- Shift of mediastinum toward the unaffected side
- Lung collapse
- air in the pleural cavity caused by a puncture of the lung or chest wall

Pneumothorax on CT

Heart MRI

Diagnostic procedure that uses strong magnets and radio waves to produce images of the heart. Is non invasive and safer than other tests.
