[Function scintigraphy of the heart in patients with heart valve diseases].

In 58 patients suffering from either stenosis or insufficiency of a single heart valve, gated blood pool scintigraphy was performed to determine the ejection fraction as well as the peak filling and peak ejection rates. It could be demonstrated that in patients with valvular disorders the ejection fraction was only moderately decreased, generally remaining in the lower reference range. The peak filling and ejection rates showed no pathologic changes with the exception of patients with aortic regurgitation where these rates were significantly decreased. Thus, the estimation of left ventricular peak filling and ejection rates may permit diagnosis of myocardial impairment in patients with valvular disease even under resting conditions.

[The effect of urinary obstruction on the results of catheterless divided 131I hippuran clearance studies (author's transl)].

During catheterless renal 131I Hippuran clearance studies, the function of each kidney can be calculated from the area integral, which is derived from the total body curve and to segments of phase II of each nephrographic curve measured for 120 seconds after the injection. For this it is assumed that the course of this phase depends entirely on the function of the renal parenchyma and is not affected by other factors such as urinary obstruction. During investigations of obstructed kidneys, considerable discrepancies were found repeatedly between clearances calculated by this method and the operative findings of a paper thin renal parenchyma of the kidney in question. In two cases it has been shown for the first time that there is an unexpected and surprising change in phase II. It follows that urinary obstruction falsifies the results of 131I Hippuran clearance tests, leading to an overestimate of the function of the obstructed kidney.
