X-Ray Scaning
An X-ray is a quick and painless procedure that produces images of the internal structures of the body, specially the bones.
In this procedure, X-rays beams pass through the body. These beams are absorbed in different amounts depending on the density of the material they pass through. Metal and bones are dense materials that show up as white on an X-ray report. The air in the lungs show up as black. Fat and muscles appear as different shades of grey.
Sometimes, a contrast medium – such as barium or iodine are introduced in the body to provide a better detail on the images. An X-ray technology is used to examine the different parts of the body. It is used to detect fractures and infections in the bones and teeth. It is also used to detect arthritis, dental decay or osteoporosis. An X-ray can also reveal bone tumors. An X-ray is used to detect problems in the chest such as lung infections or conditions, enlarged heart, blocked blood vessels or breast cancer. It is used to also detect abdominal problems such as digestive tract problems or swallowed items.
There are some risks associated with x-rays as the body undergoes radiation exposure. Sensitivity to radiation depends on the age, with children being more sensitive than adults.
Freequently Asked Questions About X-Ray
Q1. What is X-Ray used for?
X-rays are used to examine most areas of the body. They are primarily used to have a closer look at the joints and bones, although they’re sometimes also used to detect problems affecting the soft tissues. An X-ray is useful for detecting bone fractures and breaks.
Doctors suggest an X-ray to check symptoms in the body. It is used for diagnosing injuries and for dental checks. It is also used for mammography, to study joint changes and arthritis.
Q2. What is the Difference between an MRI, CT and an X-Ray?X-rays and CT scans use a small amount of ionizing radiation to produce images, while an MRI scan uses powerful magnets and radio waves to create images instead of ionizing radiation.
An MRI scan does not expose you to radiation, while a CT scan or an X-ray exposes you to radiations. An MRI scan produces a 3-dimensional image of the internal body parts. These are clear images of the internal soft tissues. A CT scan or an X-ray does not produce as clear images as an MRI scan. A CT scan or an X-ray are often used to detect conditions with the nerves or brain and muscles.
Q3. What are the 2 types of X-Rays?The two types of X-rays are characteristic radiation and bremsstrahlung radiation.
Characteristic Radiation – When a high energy electron collides with an inner shell electron, both are ejected from the tungsten atom leaving a ‘hole’ in the inner layer. This is filled by an outer shell electron with a loss of energy emitted as an X-ray photon.
Bremsstrahlung Radiation – When an electron passes near the nucleus it is slowed and its path is deflected. Energy lost is emitted as a bremsstrahlung X-ray photon. Approximately 80% of the population of X-rays within the X-ray beam consists of X-rays generated this way.
Q4. How much does a X-Ray cost?An X-ray test is cheaper as compared to an MRI or a CT scan. Different states and countries have different prices of X-rays. The basic prices of X-rays in India are between Rs. 150 to 200.
