title: Contrast enhancement by bolus technique in the CT examination of the kidney.
abstract: Clinical results of contrast enhancement by bolus technique in the CT study of the kidney, performed with a two second scanner, are presented. The value of the method is discussed in relation with congenital abnormalities and more extensively in the evaluation of mass lesions of the kidney. In comparison with the widely used contrast infusion technique for CT examination, early scans after contrast enhancement by bolus technique allow better study of anatomical details of the normal kidney and variants. Furthermore in mass lesions assessment of vascularity leads to better differential diagnosis.
