Study the difference between the measurement of the radiation dose of MRI and CT scan

Radiation dose or absorbed dose means that the amount of energy absorbed by human tissue, and accurately is the concentration of energy deposited in tissue, when exposure to ionizing radiation, effective dose is the dose that will achieve the desired effect its unit is (millisievert or mSv). Ionizing radiation used in computed tomography (CT) scans as well as the associated health risks are an ongoing and growing concern.
The aim of this study is to prove the use of X-rays and computed tomography with a small dose of ionizing radiation to produce images for medical examination.
An MRI scan uses powerful magnets and radio waves to create images instead of ionizing radiation. Therefore, you are not exposed to radiation when you have an MRI scan, unlike a CT scan or X-ray. In addition to reducing the examination time and cost.
Material and methods show that individual doses measured for a routine whole-body CT protocol are less than 20 mGy for all parts of the body. Thus, we conclude that the measured doses of the external organs are higher than those in the internal organs under the same conditions that are exposed to radiation Knowing that MRI does not use radiation (such as X-rays or CT scans) there are more MRI machines being produced from several companies around the world.

Result in this study, it was done evaluate the benefits of MRI and CT in diagnoses and treatment as well as for their side effects, at present and in the future.Conclusions. We have also concluded that CT is specific in certain areas of the human body such as the lungs and abdominal area and identify the areas of bone fractures, and magnetic resonance (MRI) gives us excellent image of high-definition of the spinal cord, brain and membranes, and the areas of the joints with animated images and a three – dimensional and in a record time of 15-30 minutes.
Where the diagnosis could be re-diagnosed during the procedure and after the occurrence of any side effects, unlike the tomography, which is specified in certain cases mentioned earlier, and a period of time of 5-10 minutes and cannot be returned except in special cases forced to have the effect of radiation. The final conclusion of our work, which is not only important in diagnosing, is that in the case of CT, there are no disturbing sounds and the presence of an area in which the patient can settle, unlike magnetic resonance imaging, Where the annoying resonance sounds are added to the narrowness and smallness of the place where the patient is located, but they are not considered to be of medical importance.
