Determination of renal circulation by means of angiocinedensitometry. 1978

H K Deininger, and F Heuck, and K Vanselow

This new X-ray method is based on the densitometric measurement of the speeds and the flow of injected contrast media during an angiographic examination of the vessels and the parenchyma of the kidney. Pairs of highly sensitive photoconductive cells and a Wheatstone bridge circuit are used. Minimal doses of contrast media can be detected before vascular reaction influences the renal circulation. The measurement of various parameters allows the simultaneous hemodynamic analysis of kidney function and of factors related to the morphological substrate.

D001783 Blood Flow Velocity A value equal to the total volume flow divided by the cross-sectional area of the vascular bed. Blood Flow Velocities,Flow Velocities, Blood,Flow Velocity, Blood,Velocities, Blood Flow,Velocity, Blood Flow
D001811 Blood Volume Determination Method for determining the circulating blood volume by introducing a known quantity of foreign substance into the blood and determining its concentration some minutes later when thorough mixing has occurred. From these two values the blood volume can be calculated by dividing the quantity of injected material by its concentration in the blood at the time of uniform mixing. Generally expressed as cubic centimeters or liters per kilogram of body weight.
