“…Some surveys abroad showed similar trend. Two surveys conducted in 2013 and 2018in Swiss showed that the CT scanning frequency increased by about 13% from 117 per 1000 population to 132 per 1000 over the ve years [18,19].…”

Objective:To conduct the survey on medical X-ray examination, and to explore the correlation with health economic index, including GDP, numbers of bed, outpatient, medical staff by assessing the frequencies of two categories of medical X-ray examinations. Methods: The numbers of medical radiological equipment and medical X-ray examinations in each medical institution were surveyed, and the frequencies of conventional X-ray examinations and CT scans were calculated, respectively. Their distribution characteristics were discussed through a correlation analysis between number of examination and health economic index, including GDP, beds, outpatients and medical staff. Results: The number of conventional X-ray examinations and CT scans performed in Jiangsu in 2019 was 38,255,027 and 25,149,658, respectively. Based on the total population province wide, the frequencies of the conventional X-ray examinations and CT scans were 452 and 297 per 1,000 population, respectively. The average numbers of conventional X-ray examinations were largely identical between the three categories of institutions, whereas the numbers of CT scans showed great differences. The number and frequencies of both examinationsshowed a strong linear correlation with GDP, number of beds, outpatients and medical staff. Conclusion: Number and frequency of radiodiagnostic examinations have seen a rapid increase in recent years, especially for CT scanning. The correlation between examination number and frequency and GDP, number of beds, outpatients, and medical staff may suggest a new strategy to extrapolate the frequency to the population in a sample survey.

Computed tomography (CT) is a modern examination method whose radiation characteristics vary depending on the population groups, the part of the body being examined, and other implementation conditions. The use of CT has become increasingly widespread. However, there is a growing concern regarding the harm caused by CT radiation. The opinions regarding whether low-dose CT can induce cancer differ. It is necessary to consider the research population, radiation characteristics, and different parts of the body being exposed to radiation before the application of radiation to ensure the knowledge used is scientifically sound and reasonable. Therefore, different studies have different opinions on whether low-dose CT induces cancer, and not all physicians are aware of this. The present review article aimed to impart relevant insights and a correct understanding of the hazardous effects of low-dose CT radiation on the human body and help physicians reduce unnecessary CT radiation exposure.

“…as numerous individuals undergo radiographic examinations each year (12,(39)(40)(41)(42)(43), raising awareness concerning the risk of X-ray irradiation is particularly important (39). However, to date, at least to the best of our knowledge, no specific literature has addressed methods with which to reduce X-ray exposure in China.…”

With the increasing frequency of X-ray examinations in clinical medicine, public concern regarding the harm caused by exposure to X-ray radiation is also increasing. However, some physicians are not completely aware of the dangers of exposure to X-ray irradiation. Individuals specialized in this field, including physicians, have a better understanding of these dangers, which limits the use of X-rays in medicine. the present study aimed to address strategies for reducing the harm caused by exposure to medical X-rays and increase public awareness regarding X-ray radiation. through a literature search and review, combined with the current status of clinical X-ray examination and the authors' professional experience, the present study highlights the importance of reducing X-ray exposure, and proposes several specific recommendations and measures for reducing the frequency or dose of X-ray irradiation. On the whole, the finding discussed in the present review suggest the minimal use of medical X-ray examinations and that alternative tests should be selected whenever possible. When medical X-ray screening and treatments are necessary, the risk-benefit ratio should be assessed, possibly aiming to achieve avoidable exposure. Further attention should be paid to protect sensitive glands and reduce the risks in children.
