In-Vitro Measurement of Stenoses with Spiral CT

After the first promising spiral computed tomography angiographies it is now the aim of this paper to examine the correlation between the real degrees of stenosis and those degrees measured with spiral CT. In the first in-vitro measurements good correlation results (r = 0.89−0.99) were obtained depending on the evaluation type. These results, however, need to be confirmed by further test series before spiral CT can be used for vessel diagnostics as a routine method.
