Radiology is a science term that refers to different types of tests that gives you a result in a picture for any part of the human body. Those tests provide the doctors with images that help them to see the body from the inside. Various imaging techniques are considered as a 'part of radiology including x-ray, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound and more' (History of radiology, 2017). 'When X-rays pass through human tissue, the energy imparted can be so high as to entrain genetic damage to the cells involved, subsequently resulting in radiation damage' (Vehmas, 2004). It is a very significant medical inventory that helps in the diagnosis of many diseases, particularly cancer
In 1895, the history of radiology started at the hands of Wilhelm Roentgen. He took a picture of an X-Ray of his wife and he also won a prize of Nobel because of his discovery in 1901. 'He had experimented with passing electric currents through a tube and by doing so, he succeeded to figure out how to turn this experiment into an X-ray by resulting in an image of the human body' (History of radiology, 2017).
There are many advantages of the radiology in medicine. The rapid developments in clinical radiology technology and theory have dramatically enhanced the diagnosis and treatment of diseases. Here are some of the clinical radiology benefits for the patient:

Radiologists are doctors who diagnose and treat patients by using a variety of machines that takes pictures of the inside of the human body. There are many types of tests for radiologists to use and it depends on what exactly they need to see and find out. Those tests are x-rays, CTs, and MRIs. Those machines can diagnose everything from small to serious diseases.
Although there are bunches of benefits to applying radiology, there are hazards intrinsic to the environment that needs to be understood and acknowledged especially when using MRIs. 'During imaging, the patient will be exposed to three types of magnetic fields simultaneously: The static (main) magnetic fields, Time-varying magnetic field gradients, and Radiofrequency (RF) magnetic fields'(Fletcher, 2019). The hazards that might be caused by these fields can affect the staff, the patients, and other persons within the magnetic field environment. To avoid these dangers from happening, some recommendations can be followed to do so 'MRI facilities should have their own set of Local Rules & Identify a safety officer responsible for ensuring that procedures are in effect and enforced to ensure safety in the MR environment' (Hoong, Ahmed, Nizam and Adbualla, 2003). In addition, 'having an X-ray exposes you to a less amount of radiation as well, the level depends on the part of your body that you need to have an image for it, for example, X-rays of your teeth will use less radiation than an X-ray of your spine' (Hoong, Ahmed, Nizam and Adbualla, 2003). It's important to be aware of the dangers of X-Ray and to what extent they might affect badly. It is well known that ionizing radiation in the higher dose range can cause malignancies such as cancer or damage to the unborn child in the womb. Indeed, these findings must be transferred to the lower dose range relying on appropriate presumptions and modeling.
Here are the different types of radiology in medicine:
- X-rays are the type of radiology that existed fifty years ago, and it was the first type used ever for imaging the human body.
- Ultrasound is used for checking little and soft tissues of the body. It provides 3d images as well.
- CT scans are a bit like x-rays but a little bit more accurate. It has been used to detect urgent and serious diseases and it always gives very clear images and accurate ones.
- MRI is a test that uses strong magnets and radio signals.
Today, radiology is a very essential discovery that has developed the performance of treatments in the medical field. It can be considered a vital diagnostic tool for several diseases. It also helps to control the process of the treatments for those diseases and to predict some of the outcomes that might occur. Radiology is the section of medicine that became very essential for all medical sections from the smallest fields t the biggest ones. All doctors believe that this discovery has changed and improved the world of medicine.
