The aim of this study was to evaluate the quality of dynamic radionuclide renal imaging in Egypt. 13 nuclear medicine departments participated. A functional renal phantom was imaged and interpreted as a patientlike study. Reconstruction and print outs were performed according to the clinical routine of each laboratory. Four nuclear medicine specialists anonymously evaluated the quality of the image sets. The visual scores of the experts were ranked from one to five. In addition, several numerical timeactivity parameters were calculated and compared between the laboratories. The average visual scores of the experts for the image sets were 3.3+/0.9 (range 2.44.2). Only six laboratories received a score value of 2 or higher. The average error for the time to reach maximum activity (T (max)) ranged from 23 to +16% and for the washout time to reach half activity from maximum activity (T (1/2)) ranged from 39 to +63%. These results suggest that the difference in calculated parameters between laboratories is most probably due to variations in study protocols, analysis programs and human error. The need for external quality assurance and quality improvement in nuclear renal imaging is evident and is recommended for regular use
