Compliance to radiography practice of high-kilovoltage technique for chest radiography in South South Nigeria

Abstract Background The production of a good quality chest radiograph depends on the selection appropriate kilovoltage and current–time product while keeping radiation dose to patients as low possible. This study assessed radiographers’ level compliance use high kV standard for postero-anterior (PA) X-ray in South region Nigeria. Results Seventy-seven 82 questionnaires administered were completely filled returned giving response rate 94%. Of these 77 respondents, only 74% ( n = 57) aware high-kV technique recommended procedure PA X-ray. Departmental protocols (technique chart with exposure factors) also non-existent all hospitals/diagnostic centres used this study. Thirty-one respondents males (40%); 44% 34) working public hospitals 32% 25) less than five years experience technique. On benefits, more 50% familiar benefits using X-rays. Responses varied from 77% 59) patient reduction 51% 39) better imaging airways. X-rays showed 13% compliance. Factors influencing included system (film screen /digital), tube rating unit preset/manual factors p < 0.05). Conclusions present revealed region, suggesting potential increase ionizing during radiography, hence need improve adherence standard.
