Estimation of Patient Radiation Dose during Nuclear Medicine Examinations in Sudan

Abstract

The aim of this study to Estimate of Patient Radiation Dose in Sudan for patients are referred to nuclear medicine departments for thyroid and kidneys and bone scan, were the number of patients was 322 patients. The study was conducted in the following hospital: Radiation and Isotope Center of Khartoum, Royal Care International Hospital, Al nilain Medical Diagnostic Center, National Cancer Institute, Shandi Hospital in period from Feb 2018- Aug 2021. The Dose calculated using RADAR software. The results showed that the correlation between the effective dose with patients age for renal scan were the change of effective dose increase by rate of 0.0042 for each year of the patients. And for patient’s height foe renal scan were the change of effective dose increase by rate of 0.0017 for each cm of the patients. And for patients’ weight for renal scan were the change of effective dose increase by rate of 0.0047 for each kg of the patients. And for patient’s body mass index for renal scan were the change of effective dose decrease by rate of 0.0017 for each kg\cm^2 of the patients. And for patients age for thyroid scan were the change of effective dose increase by rate of 0.0015 for each year of the patients. And for patient’s height for thyroid scan were the change of effective dose increase by rate of 0.0007 for each cm of the patients. And for patients’ weight for thyroid scan were the change of effective dose increase by rate of 0.0122 for each kg of the patients. And for patient’s body mass index for thyroid were the change of effective dose increase by rate of 0.0011 for each kg\cm^2 of the patients. And for patients age for bone scan were the change of effective dose increase by rate of 0.0091 for each year of the patients. And for patient’s height for bone scan were the change of effective dose increase by rate of 0.0049 for each cm of the patients. and for patients’ weight for bone scan were the change of effective dose increase by rate of 0.0082 for each kg of the patients. and for patient’s body mass index for bone scan were the change of effective dose decrease by rate of 0.0136 for kg\cm^2 of the patients. In conclusion the study showed that comparing between the present study with international studies worldwide, were the present study show the lowest value of dose and effective dose form all others studies for all examination’s thyroid, bone and renal scan.
