The rate of repeating X-rays in the medical centers of Jenin District/Palestine and how to reduce patient exposure to radiation

Abstract

Reduction of the patient’s received radiation dose to as low as reasonably achievable (ALARA) is based on recommendations of radiation protection organizations such as the International Commission on Radiological Protection (ICRP) and the National Radiological Protection Board (NRPB). The aim of this study was to explore the frequency and characteristics of rejected / repeated radiographic films in governmental and private centers in Jenin city. The radiological centers were chosen based on their high volume of radiographic studies. The evaluation was carried out over a period of four months. The collected data were compiled at the end of each week and entered into a computer for analysis at the end of study. Overall 5000 films (images) were performed in four months, The average repeat rate of radiographic images was 10% (500 films). Repetition rate was the same for both thoracic and abdominal images (42%). The main reason for repeating imaging was inadequate imaging quality (58.2%) and poor film processing (38%). Human error was the most likely reason necessitating the repetition of the radiographs (48 %). Infant and children groups comprised 85% of the patient population that required repetition of the radiographic studies. In conclusion, we have a higher repetition rate of imaging studies compared to the international standards (10% vs. 4-6%, respectively). This is especially noticeable in infants and children, and mainly attributed to human error in obtaining and processing images. This is an important issue that needs to be addressed on a national level due to the ill effects associated with excessive exposure to radiation especially in children, and to reduce cost of the care delivered.

Investigation of the Relationship between Body Parameters and mAs Using Non-Contact Two-Dimensional Thickness Measurement in Chest Digital Radiography

“…However, body thickness measurements, which were previously determined using a caliper/ruler [ 2 ], are prone to errors, with inaccurate thickness measurements potentially leading to improper exposure and inadequate image quality. In line with this, X-ray images of inadequate quality must be re-acquired, and the radiation dose to the patient must be increased [ 8 , 9 , 10 ]. Therefore, images of patients whose body parameters could not be accurately measured may have to be acquired with slightly higher exposure parameters to increase image quality.…”
