“Typical Values“ of Activities Administered to Pedriatics Patients in Renal Exams with 99mTc-DTPA

Abstract

99mTc-DTPA is a radiopharmaceutical employed for mofological and functional assessment of the renal system. The increase in the number of exams in nuclear medicine (NM) requires that optimization procedures are continually implemented and revised. "Picture Archiving and Communication System" (PACs) file system were utilized to count the number of scintigraphy. Record of pediatric exams from the NM service were used to verify the activities administered (MBq). The objective of this work is to evaluate the number of exams and the activities administered of the 99mTc-DTPA radiopharmaceutical in pediatric patients for suggest “typical values”. Results demonstrated that there are a high percentual difference between the activities administered for all age intervals. Furthermore, the activities administered to younger patients (0 to 1 year old) presented the higher “typical value“.
