Sonography and radiography are two important parts for medical diagnosis. These two imaging technologies help to draw images of inside body parts and tissues. Doctors get valuable information about their patients from those images which help them to diagnose diseases and provide appropriate treatment for them. Though both sonography and radiography are used for medical imaging purposes but they work on different technologies. There few basic technical difference between sonography and radiography. Read on to know more about the differences between these two medical imaging technologies.
Sonography uses ultra sound waves to produce images and radiology uses different radiation to produce images. This is the core difference between these two useful imaging systems. Doctors use radiography to diagnose few major health problems and injuries. Sonography uses ultra sound waves to produce images. Here is a brief description of the two technologies to understand the difference between them in a better way.
Sonography:
In sonography technology technicians apply ultra sound on the skin and send ultra sound waves inside the body by a transducer or probe. Then this transducer receives the sound waves coming back. A computer attached to the device receives those sound waves to produce inside images of body. This is how Ultra sound technology works. This technology doesn’t use any kind or radiation. That is why there is no possibility of radiation expose for the patients. From sonography we can see moving images of inside body parts. If patients are suffering from any swelling or infection or pain inside the body then doctors refers to a sonography test. This is a very common technology used on pregnant woman to observe the babies condition inside mother’s womb. This technology also can develop images of other body organs such as heart, kidney, blood vessels, liver, gallbladder, uterus, and so on and help doctors to determine any abnormalities.
Radiography:
In radiography, ionizing electromagnetic rays are being used to produce images of inside body parts. The very common use of this technology is x ray. This technology is being used to see the inside bone structure and doctors can determine any abnormality from those x ray images. There are many others medical equipments which use radiography technology such as mammography, fluoroscopy, angiography, CT scan, and many others. Radiography is used to check bone fractures or abnormal growths from bones, blockage or leakage from the vessels, abnormal grown inside the breast, detect brain tumors and many more major health issues. As there is chance of radiation exposure during radiography tests, technicians and doctors need to follow the all the protection protocols and do the tests under careful supervision. Radiography technicians should follow the step by step procedure and take care of the safety measures.
These are the brief description of these two major diagnostic technologies. With many more inventions and use of advance technologies many new characteristics are being added. Diseases like cancer can be determined in earlier with help of these imaging technologies. Doctors now can diagnose disease and do a better treatment with the help of sonography and radiography technology.
