Radiograph

Radiograph is a type of medical imaging that uses X-rays to visualize the internal structures of the body. It is a non-invasive procedure that can be used to diagnose and monitor various medical conditions.

History

The discovery of X-rays was made by Wilhelm Conrad Roentgen in 1895. He was awarded the first Nobel Prize in Physics in 1901 for his discovery. The first radiograph was an image of Roentgen's wife's hand.

Procedure

A radiograph is taken by passing a controlled amount of X-ray radiation through the body, capturing the resulting image on a film or digital sensor. The amount of radiation absorbed by the body is dependent on the density and composition of the tissues and structures within the body. This results in different shades of black and white on the radiograph, allowing for the visualization of internal structures.

Types of Radiographs

There are several types of radiographs, including:

• Chest radiograph: Used to diagnose conditions affecting the lungs, heart, and chest wall.
• Abdominal radiograph: Used to diagnose conditions affecting the abdomen.
• Bone radiograph: Used to diagnose conditions affecting the bones.
• Dental radiograph: Used to diagnose conditions affecting the teeth and jaw.

Risks

While radiographs are generally safe, there is a small risk of radiation exposure. However, the benefits of a radiograph often outweigh the risks, especially when it helps in diagnosing serious conditions.
