| Abstract | [Summary] Renography was performed with 123I-Orthoiodohippurate (123I-OIH) using a gamma camera and digital data acquisition system for the evaluation of renal structure and function. As for sequential renal scintigrams, both highquality parenchymal and excretory images were simultaneously obtained with a single radiopharmaceutical. They were assessed to be useful in morphological evaluation of not only renal parenchymal diseases but also obstructive nephropathy. Regional renograms and functional images derived with image processing were useful in the evaluation of regional function and extension of the regional disorder, and also in the evaluation of parenchymal function independently of pelvic function. Furthermore, calculation of renal Mean Transit Time (M.T.T.) was applied by means of determining transfer function by using the direct operational method and the values of M.T.T. were compared in various renal disorders. The mean value of M.T.T. in healthy cases was 2.99+1.72 (mean+-S.D.) minutes. The mean values of the cases with hydronephrosis and diffuse parenchymal disease were significantly prolonged. It was thought that estimation of M.T.T was useful in quatitative assessment of renal function. |
