X-ray provides the image of fractured and dislocated bones, pneumonia, and tumors CT scan provides images of soft tissues, internal organs which is very clear and understandable.X-ray machines use the light or radio waves to produce the image by scanning the affected body part and result in a 2D image CT scan is the advanced type of X-ray image producer which provides 3D image and scanned the body with 360 degrees and produces multiple X-ray which can view on the computer screen.The X-ray machine was discovered by Wilhelm Rontgen in 1895, whereas CT scan was invented Godfrey Hounsfield and Allan Cormack in 1972.Key Differences Between X-ray and CT scanįollowing are the substantial difference between X-ray and CT scan: It helps in diagnosing soft tissues, blood vessels, various internal organs. Often the patient is asked to drink a solution prior to the test, which contrasts to the CT scan image and helps radiologist to view a clear image. Once it starts scanning, the X-ray machines rotate around at 360 degrees and create many images of that part called ‘ slices,’ which can be viewed by radiologists on the monitor. It focuses on target areas much better than X-rays.ĭuring CT scan procedure, the patient is asked to lie on the table, that slides into the CT scanner. CT scan machines look likes a square box with a tunnel inside, which is considered as advanced type X-ray machines and works on the same principles as X-ray machines.ĬT scan is used to scan organs, soft tissues which provide with multiple x-ray images to create a final image, which is viewed on the monitor of the computer. Also known as a CAT (computed axial tomography) scan. In 1972, Engineer Godfrey Hounsfield and physicist Allan Cormack invented the CT (Computed Tomography) scan. Soft tissues like muscles, fats and other organs absorb x-rays to the different extent, due to which denser objects like bones absorbs much radiation and hence appear white in color on photographic film whereas soft tissues appear in shades of gray as they absorb lesser radiation. An x-ray machine produces a small explosion of radiation that passes through the focused body part which has to be examined, once this radiation passed through the body, a recorded image is produced on photographic film. It is the most commonly and easily used method all over, for detecting bones fracture, dislocation of bones, tumors, pneumonia.Īs said above these X-ray machines uses radiations of light or radio waves, these radiations pass through objects like bones, which appear white on X-ray film.

X-ray is the fastest and easiest way for health care professionals to diagnose about the bones, soft tissues, other body injuries. X-ray machines use light or radio waves kind of radiations. Radiographs are the image formed of the scanned body part on the film. Later other scientist began taking these radiographs. Wilhelm Rontgen invented the X-ray machine in 1895. Not easily available in rural and small hospitals. Sometimes radiations can be harmful if precautions not taken. Internal organs injuries details are not clearly visible. Uses 360-degree x-ray beam and images produced can be seen on the computer screen which is more powerful and clear. Used to produce deep and high-quality images. Internal organs, soft tissues, blood vessels. Godfrey Hounsfield and Allan Cormack in 1972.įractured bones, dislocation of bones, pneumonia, tumours. X-ray machines uses the light or radio waves as radiation for scanning the effected body part like fracture, bones dislocation, lungs infections, pneumonia, tumours.ĬT scan (Computed Tomography) process is a kind of advanced x-ray machines, which provide the much detailed structure of the affected body part and even more clear images of the internal soft tissues and organs. Given below are the few more differences in table form, which will help to distinguish among them more clearly. The process of diagnosing is performed under the supervisor known as Radiologist.

There are various types of machines used to detect diseases but most commonly these two are used. To know the better and accurate cause of disease, illness, fractures, bones abnormalities or pain, doctors advised for X-rays or CT Scan (Computed Tomography) process. Images produced by X-ray are in 2D, whereas 3D images are formed in CT scan. Secondly, X-ray machines sometimes fail in diagnosing soft tissues, muscles damage and other body organs, which is possible through Computed Tomography procedure commonly known as CT scan.
