According to author's experience static renal scintigraphy using pinhole collimator gives detailed image of kidneys. In group of 14 children with different findings in number of renal reductions or defects kidneys with more defects were found.
There was no solitary renal defect seen only on the image using pinhole collimator, which would lead to a change of the diagnosis. Only single images using pinhole collimator by static renal scintigraphy aren't sufficient; they don' t consider the accumulative capability of kidneys including mathematic analysis of global and separate renal function.
Static renal scintigraphy supplemented by pinhole collimator images becomes a more precise examination, which can better consider the number and extent of renal parenchymal changes.
