Diagnostic 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 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...
متن کاملA SOFTWARE ENGINE TO JUSTIFY AN EXPERT SYSTEM’S CONCLUSIONS FOR DETECTING RENAL OBSTRUCTION FROM Tc-99m MAG3 SCANS
Objectives: We have previously developed a renal expert system (RENEX) as a decision support tool to assist in the interpretation of Tc-99m MAG3 scans to detect renal obstruction in patients referred for diuresis renography. A decision support system may give the right answer for the wrong reasons. This study is to describe and evaluate a software engine to justify the conclusions reached by RE...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
