Abstract
The aim of this study was to compare a simple measure obtained visuall y from serial images, the corticopelvic transfer index (CPI), with ren al transit times obtained by deconvolution. The CPI was defined as the time interval between the appearance of the tracer in the renal corte x to its appearance in the renal pelvis. Four groups of subjects as de termined by clinical data and renal transit times were investigated re trospectively: 86 normal kidneys, 20 kidneys with renovascular disorde r, 17 kidneys with obstructive nephropathy and 26 kidneys with dilated pelves without obstructive nephropathy. There were good correlations only between the CPI and mean parenchymal transit time (MPTT; r = 0.6) and the whole kidney transit time index (WKTTI; r = 0.8). It was conc luded that in centres where gamma-camera studies with deconvolution an alysis are not possible, the CPI could be a useful parameter in renal radionuclide scintigraphy for suspected renovascular disorders.
