Tīmeklisturn is a reflection of renal blood flow. Renogram curves looking at uptake and drainage of MAG3 have been defined by O’Reilly et al [16]. Normally, the time required for clearance of 50% of the accumulated radionuclide (t½) is <10 min, while a t½ of >20 min is suggestive, but not diagnostic, of obstruction. Four types of renogram curves ... TīmeklisA normal or slowly declining renogram curve effectively excluded KTO (sensitivity of 96%, negative predictive value of 84%). A parenchymal transit time of > 5 min and a TTB of > 7 min both yielded a sensitvity of 92% and a specificity of 81%.
