computed tomography and dynamic computed tomography revealed that hypertensive disease was characterized-by normal volume and thickness of the renal cortical layer and symmetric time-density curves , whereas a hypertensive type of chronic glomerulonephritis featured lower renal cortical layer thickness , reduced renal volume , symmetrically decrease amplitudes of the first and second peaks of the time-density curve , chronic pyelonephritis showed asymmetric time-density diagrams due to the lower density areas in the afflicted kidney .
