Life Time Attributable Cancer Risk Estimated Using Scanner Reported Dose Length Product during Chest Computed Tomography Imaging in Young Children

引用

Open Journal of Radiology 2024年第2期14卷 74-82页

作者： Mousa Bakkari Khaled Soliman Abdullah Alrushoud Marwan Fahad Alosaimi Hanaa alsheikh Abdelwahed Alhejaili Medical Physics Department Prince Sultan Military Medical City Riyadh Saudi Arabia Radiogiadnostic and Medical Imaging Department Prince Sultan Military Medical City Riyadh Saudi Arabia

This study aims to estimate the lifetime attributable cancer risk (LAR) for pediatric chest computed tomography (CT) examinations in five age groups using recently published age and region-specific conversion coefficients multiplying the widely available scanner registered dose length products (DLP) displayed on the CT console and hence calculating the Effective Dose (ED). The ED is then multiplied by the International Commission on Radiological Protection (ICRP) published risk factor for LAR. The obtained LAR values are compared with the international literature. Factors that may affect the LAR value are reported and discussed. The study included one hundred twenty five chest CT examinations for both males and females aged from less than one year to fifteen years. The patients reported data are from one single medical institution and using two CT scanners from June 2022 to December 2023. The results of this study may serve as benchmark for institutional radiation dose reference levels and risk estimation.

Relationship between Whole Body Iodine-131 Effective Half-Life and Estimated Glomerular Filtration Rate for Papillary Thyroid Cancer Patients Undergoing Radioactive Iodine Therapy

引用

Journal of Applied Mathematics and Physics 2023年第8期11卷 2472-2479页

作者： Asim Abualnaja Hanaa alsheikh Khaled Soliman Meshal Alnefaie Abdulraheem Alsheri Medical Physics Department Prince Sultan Military Medical City Riyadh Saudi Arabia Radiodiagnostics and Medical Imaging Department Prince Sultan Military Medical City Riyadh Saudi Arabia

Background: The aim of this work was to examine the relationship between the estimated glomerular filtration rate (eGFR) as indicator of renal efficiency potentially related to the ability to release radioactive iodine from the patients bodies and the radioactive iodine whole body effective half-life (WBEHL) defined as the time taken for the administered activity to decay to half of its value for papillary thyroid cancer (PTC) patients undergoing radioactive iodine therapy (RAIT) in a tertiary care medical Centre. Methods: This retrospective observational study included seventy nine patients, sixty females and nineteen males. The patients were divided in two subgroups, those who have WBEHL of less than 11 hours (n = 51) and those with more than 11 (n = 28) hrs based on k-means clustering technique. Results: Analysis of variance (ANOVA) was used to find out if there is a statistically significant difference between the two subgroups Conclusion: There was not a statistically significant difference between the short and the longer WBEHL patients’ groups analyzed in this study. .

AIM To assess the association of inter-ethnic vs intra-ethnic marriage with severity of coronary artery disease(CAD) in men undergoing *** We conducted a prospective multicenter,multi-ethnic,cross sectional observational study at five hospitals in Saudi Arabia and the United Arab Emirates,in which we used logistic regression analysis with and without adjustment for baseline differences. RESULTS Data were collected for 1068 enrolled patients undergoing coronary angiography for clinical indications during the period of April 1^(st),2013 to March 30^(th),2014. Ethnicities of spouses were available only for male patients. Of those enrolled,687 were married men and constituted the cohort for the present analysis. Intra-ethnic marriages were reported in 70% and inter-ethnic marriages in 30%. After adjusting for baseline differences,interethnic marriage was associated with lower odds of having significant CAD [adjusted odds ratio 0.52(95%CI:0.33,0.81)] or multi-vessel disease(MVD) [adjusted odds ratio 0.57(95%CI:0.37,0.86)]. The adjusted association with left main disease showed a similar trend,but was not statistically significant [adjusted odds ratio 0.74(95%CI:0.41,1.32)]. The association between interethnic marriage and the presence of significant CAD and MVD was not modified by number of concurrent wives(P interaction > 0.05 for both).CONCLUSION Among married men undergoing coronary angiography,inter-ethnic,as compared to intra-ethnic,marriage is associated with lower odds of significant CAD and MVD.
