Abstract
The theoretical basis for and the technique of intravenous contrast enhancement by bolus injection for dynamic CT examination of the kidney are described. The clinical applications of this method include the study of normal vascular anatomy of the kidney, congenital kidney abnormalities and form variants, space-occupying lesions, and kidney trauma. In tumoral lesions of the kidney, dynamic CT aids in detecting the lesion as well as in the tumor staging and evaluating operability. CT time density curves can be used to study disturbances in renal perfusion, but the clinical value of this method needs further confirmation.
