Biokinetics, dosimetry, and radiation risk in infants after 99mTc-MAG3 scans
BACKGROUND Renal scans are among the most frequent exams performed on infants and toddlers. Due to the young age, this patient group can be classified as a high-risk group with a higher probability for developing stochastic radiation effects compared to adults. As there are only limited data on biokinetics and dosimetry in this patient group, the aim of this study was to reassess the dosimetry ...
متن کاملDiagnostic performance of an expert system for interpretation of 99mTc MAG3 scans in suspected renal obstruction.
UNLABELLED The purpose of the study was to compare diuresis renography scan interpretation generated by a renal expert system with the consensus interpretation of 3 expert readers. METHODS The expert system was evaluated in 95 randomly selected furosemide-augmented patient studies (185 kidneys) obtained for suspected obstruction; there were 55 males and 40 females with a mean age +/- SD of 58...
متن کاملRENEX: an expert system for the interpretation of 99mTc-MAG3 scans to detect renal obstruction.
UNLABELLED A renal expert system (RENEX) has been developed to assist physicians detect renal obstruction in patients undergoing pre- and postfurosemide 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) scans. RENEX uses quantitative parameters extracted from the dynamic renal scan data and heuristic rules in the form of a knowledge base (KB) obtained from expert interpreters to conclude whether a ki...
متن کاملAdministered activity optimization in 99mTc-MAG3 renography for adults.
OBJECTIVE The objective of this work was to determine the minimum administered activity of (99m)Tc-mercaptoacetyltriglycine (MAG3) needed both to estimate effective renal plasma flow (ERPF) with adequate precision and to obtain good image quality. METHODS Three groups of 10 patients each were injected with 45, 71, or 132 MBq of MAG3. Renograms and perfusion and clearance images were obtained....
متن کاملA software engine to justify the conclusions of an expert system for detecting renal obstruction on 99mTc-MAG3 scans.
UNLABELLED The purposes of this study were to describe and evaluate a software engine to justify the conclusions reached by a renal expert system (RENEX) for assessing patients with suspected renal obstruction and to obtain from this evaluation new knowledge that can be incorporated into RENEX to attempt to improve diagnostic performance. METHODS RENEX consists of 60 heuristic rules extracted...
