For the evaluation of the symmetry of hemispherical bolus transit the following parameters were used: the cumulative L/R hemispheric ratios expressed in arctangent values and the sequential hemispheric activity difference. Both the sensitivity and specificity of this technique for detection of proven stenosis of carotid or cerebral arteries (25 cases) were 80%, in comparison with 60% for computerized axial tomography.
