[Non-quantitative analysis of the renography using 99mTc-DTPA; clinical efficacy and limitation].

The purpose of this paper is to evaluate the efficacy and limitation of the non-quantitative analysis of renography using 99mTc-DTPA, and to determine the clinical indication of the quantitative analysis of the study. We evaluated the clinical records of the patients and the findings of dynamic imagings and renograms. The non-quantitative analysis of the examination seemed to be useful to the selected cases, and quantitative analysis appeared to be dispensable except for the cases to evaluate the grade of parenchymal damages and causes of asymptomatic hematuria.
