Radionuclide and differential radiodiagnosis of renal parenchymal tumors versus nontumorous renal diseases

Modern radiation semiotics of kidney parenchyma cancer and nontumoural diseases of kidney parenchyma is described. Their new indices are shown, the place and significance of radionuclide and roentgenologic methods for the differential diagnosis of kidney parenchyma cancer and nontumoural kidney parenchyma diseases are shown. The plan described is nowadays one of the most rational diagrams. The diagnostic value of roen-- tgenologic and radionuclide investigations of kidney parenchyma cancer is not equivalent. Radio-indication methods state changes which are not characteristic of a particular disease. Therefore, they are used as tests for the further purpose ful special roentgenologic investigation with the minimum traumaticity which improves the diagnosis of kidney parenchyma cancer and permits to reduce investigation periods and material expenditure
