Estimation of patient's radiation diagnostic doses in nuclear medicine

Abstract

This study intends to estimate the patients radiation diagnostic doses in nuclear medicine. A total of 60 patients were examined in two Hospitals. The data were collected using a sheet for all patients in order to maintain consistency of the information. The following parameters were recorded age, weight and height to estimate the dose for thyroid scan, renal scan and bone scan. The examinations were collected according to the availability. The mean age, weight and height are 77.37, 66.76 and 1.64 respectively for male in elneelian center.The mean age, weight and height are 59.70, 67.86 and 1.61 respectively for female in elneelain center. The mean age, weight and height are 70.17, 69.34 and 1.62 respectively for male in elmek nimer hospital. The mean age, weight and height are 51.33, 62.40 and 1.68 respectively for female in elmek nimer hospital The mean doses of thyroid, renal and bone scan are 5.04, 9.19 and 20.10 respectively in elneelain center. The mean doses of thyroid, renal and bone scan are 5.24, 8.05 and 22.10 respectively in elmek nimer hospital. Patient doses were measuring during this study used on two hospitals to three types of organ diagnosed. demographic data (age, weight, height, sex, clinical indication, and type of organ diagnosed) were meausured. Dose calibrator were used to measure organ doses. Two different gamma camera machines were used throughout this study. In this study bone scan doses values were higher than the other two types of diagnosed while thyroid scan diagnosed is lowest one.
