“…With external accreditation standards requiring medical radiation students to become competent in CT, the implementation, and utilisation of CT simulator is imperative (MRPBA, 2019). Conventional methods and actual scanning time are effective in developing theoretical and practical CT elements (Hawarihewa et al, 2021); this is reflected in the mixed responses regarding whether simulator technology has comparable effectiveness to the real CT experience. However, the use of CT simulation certainly appears to assist students' perception of CT competence, within a safe learning environment (Liley et al, 2018; Lee et al, 2020).…”

Background Simulation-based learning is a crucial educational tool for disciplines involving work-integrated learning and clinical practice. Though its uptake is becoming increasingly common in a range of fields, this uptake is less profound in diagnostic radiography and computed tomography. Aim This study explored whether CT simulator software may be a viable option to facilitate the development of practical clinical skills in an effective, safe and supported environment. Methods A cross-sectional mixed methods design was employed. Students in their third year of study undertook formal simulation CT learning using the Siemens SmartSimulator, prior to a six-week off-campus clinical experience. A pre- (n = 42, response rate = 39%) and post-clinical placement Likert scale survey was completed (n = 21, retention rate = 50%), as well as focus group interviews to gather qualitative data (n = 21). Thematic analysis was employed to explore how the simulator developed students’ knowledge of CT concepts and preparedness for clinical placement. Results Survey scores were high, particularly in terms of satisfaction and relevancy. Focus groups drew attention to the software’s capacity to build on foundational principles, prepare students for placement and closely emulate the clinical environment. Students highlighted the need for continual guidance and clinical relevance and maintained that interactive simulation was inferior to real-world clinical placement. Conclusion The integration of CT simulator software has the potential to increase knowledge, confidence, and student preparation for the clinical environment.

“…The advantages of magnetic resonance imaging, which doctors prefer to be clear, can be three -dimensional, easy to store on the computer or disk and re-use several times. During surgery, several images can be taken by MRI to identify the results of the operation without side effects [8,9].…”

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.
