N2  - 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 patient{u2010}like 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 time{u2010}activity  parameters were calculated and compared between the laboratories. The average visual  scores of the experts for the image sets were 3.3+/{u2010}0.9 (range 2.4{u2010}4.2). 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 {u2010}23 to +16% and for the washout time to reach  half activity from maximum activity (T (1/2)) ranged from {u2010}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
