Difference Between X-Ray and CT Scan

X-ray and CT scans are imaging techniques used to diagnose internal illness. Both of these tests use a low ionization energy beam to detect internal defects such as bone fracture, internal swelling, and pre-surgery checkups.

Also, these tests provide clear and significant images of the internal body.

X-Ray vs CT Scan

The difference between X-ray and CT scan is that X-ray produces a single image whereas CT scan produces multiple images from different angles. X-ray produces an image in a single position whereas, in a CT scan, multiple images are produced from different angles.

X Ray vs CT Scan

X-ray is a low ionization energy imaging test. Depending upon the density of the bones, these rays are absorbed in various portions. denser body parts, such as bones and teeth, are represented by white color in X-ray film.

On the other hand, lesser dense parts such as muscle and fat appear in grey and air-filled in lunges are shown in black color.

CT scan is technically known as a computerized tomography scan. Also, a separate computer program and processing is used to construct cross-sectional slides of the blood vessels, bones, and soft tissues of our body.

Moreover, CT scan images provide more detailed information than plain X-rays do.

Comparison Table

Parameters of ComparisonX-RayCT Scan
DefinationX-ray is a rapid and painless test that creates images of the bony structure present inside our body.CT scan is formed by combining a sequence of X-ray images taken from multiple angles around our body.
DiagnosisX-ray is used to investigate problems that occurred in many body parts such as bones and teeth, ribs, chest, and abdomen.CT scan is used to construct cross-sectional slides of the blood vessels, bones, and soft tissues of our body.
DetailsX-ray does not provide much information as X-ray istaken in a single position and one angle.CT scan images provide more detailed information than plain X-rays do.
PriceX-ray is quiet affordable and pocket friendly.CT scan is little bit costly as compared to an X-ray.
Ionisation Energy LevelX-ray uses a low ionisation energy beam.CT-scan uses a high ionisation energy beam as compared X-ray.

What is X-Ray?

X-ray is a rapid and painless test that creates images of the bony structure present inside our body. X-ray beams are ejected through a machine and the patient is allowed to stand in front of the machine.

These beams penetrate through our body and are made to project an image on a screen or film.

Depending upon the density of the bones, these rays are absorbed in various portions. Furthermore, denser body parts, such as bones and teeth, are represented by white color in X-ray film.

On the other hand, lesser dense parts such as muscle and fat appear in grey and air-filled in lunges are shown in black color.

For some special types of X-ray tests, some non-toxic iodine or barium solutions are given to patients for drinking. These solutions provide a better and more detailed image of the affected area.

X-ray is used to investigate problems that occurred in many body parts such as bones and teeth, ribs, chest, and abdomen.

In the case of bones and teeth, an X-ray is used to detect fractures, bone cancer, arthritis, osteoporosis, tooth decay. Whereas in the case of the chest, an X-ray is used to diagnose lungs infection, enlarged heart, breast cancer, and blocked blood vessels.

However, abdominal X-rays are used to detect digestive tract infections and sometimes swollen items in the case of children.

What is CT Scan?

A CT scan is technically known as a computerized tomography scan. It is formed by combining a sequence of X-ray images taken from multiple angles around our body.

Furthermore, a separate computer program and processing is used to construct cross-sectional slides of the blood vessels, bones, and soft tissues of our body. Moreover, CT scan images provide more detailed information than plain X-rays do.

CT scan is mainly used to diagnose internal injuries from any type of accident or any other trauma. Also, a CT scan is preferably used to schedule surgery or medical therapy and analyze an injury or a disease.

Furthermore, a CT scan is mainly used to detect any bone and muscle disorders, infection, tumor, internal blood clot or injuries, and internal bleeding. Since a CT scan captures more details than an X-ray, the amount of radiation is also more as compared to a plain X-ray.

In a special type of CT scan, a special non-toxic chemical known as contrast material is inserted into the patient’s body through injection or by an oral method.

If the esophagus or stomach is being scanned, contrast material is given through the oral method. If gallbladder, urinary tract, liver, or blood vessels are being scanned, then contrast material is given through injection.

Main Differences Between X-Ray and CT Scan

  1. X-ray displayed only a single film for an affected part. Whereas, CT scan displays a film by combining multiple X-rays from different angles.
  2. X-ray is used to detect fractures, bone cancer, arthritis, osteoporosis, tooth decay, lungs infection, enlarged heart, breast cancer, and blocked blood vessels. On the other hand, a CT scan is used to diagnose any bone and muscle disorders, infection, tumor, internal blood clot or injuries, and internal bleeding.
  3. In some special kinds of X-rays, some non-toxic iodine or barium solutions are provided to patients for drinking. Whereas in CT scan, some non-toxic contrast material is given to the patients.
  4. The price for an X-ray is quite low and is affordable. On contrary, a CT scan is quite expensive and is not easy to afford.
  5. X-ray uses a low ionization energy beam of rays whereas CT scan uses a bit higher ionization energy beam as compared to X-ray.
