Chest x-ray

Definition

A chest X-ray (CXR) is a radiographic image of the thoracic cavity, including the heart, lungs, and bones. It helps diagnose various pulmonary conditions and assess the impact of diseases on the respiratory system.

5 Must Know Facts For Your Next Test

1. Chest X-rays can reveal changes in lung structure due to chronic conditions like COPD or acute issues such as pneumonia.
2. Nutritional deficiencies, such as low protein levels, can lead to muscle wasting which may be visible on a chest X-ray as decreased diaphragm strength.
3. Excessive fluid intake or imbalances in electrolytes can contribute to pulmonary edema, which is detectable on a chest X-ray.
4. Malnutrition can weaken the immune system, making individuals more susceptible to respiratory infections that can be identified via chest X-rays.
5. Certain nutritional interventions might help alleviate symptoms visible on chest X-rays, such as improving lung function through antioxidants found in a balanced diet.
