“…It is important to note that while DRLs provide a useful benchmark, they should not be used as an absolute standard, as the appropriate radiation dose for an individual patient will depend on many factors, including their medical history, the type of exam being performed, and the specific imaging equipment being used [ 22 ].…”

“…Various studies have used different dose indices for establishing DRLs. Most of the studies [ 13 , 24 , 25 , 27 ] reported CTDI vol index over CTDI w since most of the scanners were multi-slice and programmed in a spiral model; this incorporates pitch in, the quantification of the dose output for a specific protocol, whereby the dose index is represented by CTDI vol [ 22 ]. Overall, CTDI vol and DLP are the recommended dose indices for CT DRLs by ICRP, and the European commissions are the most widely reported dose metrics found in the current review [ 22 ].…”

Even though CTDI vol and CTDI w are still being used to register DRLs in various studies, comparison of doses is a challenge because these two dose indices are not the same.…”

Eligibility criteria: A cohort study (observational design) reporting DRLs in adult patients undergoing computed tomography (CT) for radiation therapy for the region head and neck or pelvis were included. The comprehensive literature searches for the relevant studies published between 2000 and 2021 were performed using PubMed, Scopus, CINHAL, Web of Science, and ProQuest. Results: Three hundred fifty-six articles were identified through an extensive literature search. Sixty-eight duplicate reports were removed. The title and abstract of 288 studies were assessed and excluded if they did not meet the inclusion criteria. Sixteen of 288 articles were selected for full-text screening (studies conducted between 2000 and 2021). Five articles were included in the review after the full-text screening. Conclusion: A globally approved standard protocol that includes scanning techniques, dose measurement method, and DRL percentile needs to be established to make a valuable and accurate comparison with international DRLs.

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. 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.
