Evaluation of Patient and Staff Doses in Brain Intervential Radiography
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2016, Vol 4, Issue 4
Abstract
Abstract: Interventional Radiology (IR) improved the diagnosis and treatment of many of pathologies. This study aimed to evaluate the patient ESAK in brain IR procedures. A total of 100 patients were examined in Royal Care hospital, Khartoum, Sudan. Patients ESAK was calculated using patients imaging parameters and X ray tube output. Patient individual exposure parameters were recorded. The mean exposure parameters values were 70.0 kV for the tube voltage, mAs=10.3 for the tube current time product. The mean patient age was 41.0. The mean ESAK was 11.5 and dose value in terms of dose area product (DAP) was 1238.8 and the mean fluoroscopic time (f.t) was 4.22±.86 minute. and D.O.P (32.75±1.893, 34.50±6.05). The correlation coefficient which is defined as a measure of the degree of linear relationship between two variables, usually labeled X and Y used in this study to describe the relation between two variables affect patient dose ESD(mGy) against tube current time product(mAs) and floro time(f.t) and dose area product (DAP) . And (DAP) against duration of procedure (D.O.P) Positive correlation coefficients were obtained between these values. This means if the value of mAs or kV increases the value of the ESD increases.
