“…Table 3 compares the examination and projection measurements of this study with those of other studies. The results showed a good agreement between the results of the present study and those of Rasuli et al (13) and Mettler et al (5) as depicted in Table 3. The variation with other works is related to the difference in irradiation parameters (e.g., tube voltage, total filtration, and beam direction).…”

“…ED value is the total of the weighted equivalent doses to the determined organ, and gives a useful quantity to assess radiation hazards (ICRP). Monte Carlo method requires the ESD, tube voltage, X-ray tube filtration, current-time product, age, sex, height, and weight of patient, as well as determining the area of the anatomical regions across images (12)(13)(14). ESD can be expressed by the following equation 5:…”

Background: In conventional X-ray examinations, patients are exposed to radiation. Biological hazards from radiation of any source is expressed as effective dose, and is measured in millisieverts (mSv). The purpose of this study was to assess and calculate the effective dose values for patients undergoing posteroanterior (PA) chest, abdomen, anteroposterior (AP) pelvis, and cervical spine X-ray examinations in general hospitals of Erbil city and compare it with those of other studies. Materials and Methods: A total of 255 patients between 20-70 years of age participated in this work (85 per hospital). The patients’ characteristics included age, sex, examination type, projection posture, and exposure parameters captured by NOMEX Multimeter including tube potential and current-time product. The mean effective doses (EDs) of four different examinations (chest (PA), pelvis (AP), abdomen, and cervical spine) were measured using the Monte Carlo method and compared with those of other studies. Results: The mean EDs were calculated 1.04, 2.01, 3.12, and 3.22 mSv for chest (PA), pelvis (AP), abdomen, and cervical spine, respectively. All ED values in this study were higher than those of published studies. The aim of the study was to increase the awareness of the radiographer and patients undergoing conventional X-ray diagnostic radiology on the risk of ionizing radiation for radiological protection in Erbil hospitals. Conclusion: The mean EDs were increased by an increase in the age; this may increase the probability of cancer incidence and heritable diseases. Hence, dose optimization is required due to more probable incidence of cancer when compared to other studies.

“…The challenges facing Iran are to build the healthcare infrastructures, to provide medical imaging equipment and try to attract qualified specialists with the limitation of financial resources [9,10]. Few patient dose assessments have been conducted in Iran [11][12][13][14][15][16][17]. Iran also did not participate in the IAEA international patient dose survey, which makes these types of studies more important [18].…”

Introduction: The main purpose of this study was to investigate patient dose in pelvic and abdomen x-ray examinations. This work also provided the LDRLs (local diagnostic reference levels) in Khuzestan region, southwest of Iran to help establish the NDRLs (national diagnostic reference levels). Methods: Patient doses were assessed from patient's anatomical data and exposure parameters based on the IAEA indirect dosimetry method. With regard to this method, exposure parameters such as tube output, kVp, mAs, FFD and patient anatomical data were used for calculating ESD (entrance skin dose) of patients. This study was conducted on 250 standard patients (50% men and 50% women) at eight high-patient-load imaging centers. Results: The results indicate that mean ESDs for the both pelvic and abdomen examinations were lower than the IAEA and EC reference levels, 2.3 and 3.7 mGy, respectively. Mean applied kVps were 67 and 70 and mean FFDs were 103 and 109, respectively. Tube loadings obtained in this study for pelvic examination were lower than all the corresponding values in the reviewed literature. Likewise, the average annual patient load across all hospitals were more than 37000 patients, i.e. more than 100 patients a day. Conclusions: The authors recommend that DRLs (diagnostic reference levels) obtained in this region, which are the first available data, can be used as local DRLs for pelvic and abdomen procedures. This work also provides that on-the-job training programs for staffs and close cross collaboration between physicists and physicians should be strongly considered.

“…In practice, there are a number of causes behind these variations. For instance, setting different exposure factors among different X-ray units for the same X-ray projection would lead to different radiation exposure [31]; operators with different experience levels may cause the variability in the radiographic practice; finally, patients' sizes and could also impose certain limitations that can be reflected on the patients dose consistency at different units [32].…”
