“…It is also interesting that the reduction in renal artery blood flow is proportional to the osmolality of the injected contrast bolus (Russell & Sherwood, 1974). We have shown the magnitude of the vasopressin response also to be related to the osmolality of the injected contrast agent.…”

We have previously reported that intravenously administered contrast media produce a rise in plasma vasopressin (antidiuretic hormone) concentrations. We have now shown that this occurs both when contrast medium is injected into a peripheral vein and when it is centrally injected into the right atrium. The peak vasopressin concentration recorded varies with the osmolality of the contrast medium. The vasopressin response was greater when contrast agent was centrally injected.

“…A biphasic change in blood flow in the renal artery during renal arteriography has been reported by Russell and Sherwood (1974). They found a rise in blood flow 10 s after the injection of contrast medium, followed by a fall 35-45 s after the contrast injection.…”

“…Contrast agents are known to decrease renal blood flow (Russel & Sherwood, 1974) and this may account for the lower values obtained for the renal cortex. It should be remembered that the values obtained using xenon are derived using compartmental analysis, identifying a physiological rather than an anatomical compartment.…”

Measurement of tissue perfusion by dynamic computed tomography

A method for quantifying tissue perfusion by dynamic computed tomography (CT) is described. By applying a nuclear medicine data processing technique to time-density data from a single-location dynamic CT sequence, tissue perfusion can be determined from the maximum gradient of the tissue time-density curve divided by the peak enhancement of the aorta. Using this method, splenic perfusion was measured at 1.2 ml min-1 ml-1, normal renal cortical perfusion at 2.5 ml min-1 ml-1 and normal renal medullary perfusion at 1.1 ml min-1 ml-1. Changes in cortical and medullary perfusion in renal failure and hypertension were demonstrated. The ability of dynamic CT to provide quantitative functional information is not well recognized and is potentially of value when studying structures, such as the renal cortex and medulla, that cannot be anatomically resolved by standard functional imaging techniques.
