BACKGROUND: To analyze the co-occurrence of @entity731 in CT angiograms of extra and intracranial arteries in @entity1 with cerebral circulation insufficiency. MATERIAL/METHODS: Extra-and intracranial CTA was performed in 70 @entity1 with symptoms of cerebral circulation insufficiency. Co-occurrence of @entity731 at both levels and correlation between the degree of @entity731 and sex, age, and clinical symptoms were evaluated. Intracranial CTA results were compared to those of the control group, which consisted of 34 subjects asymptomatic of cerebral circulation insufficiency. The usefulness of various data reconstruction techniques ( @entity11542 and MPR vs. @entity11542 only) for the evaluation of @entity932 was subjected to independent analysis by two radiologists. RESULTS: Concomitant occurrence of extra-and intracranial lesions was diagnosed in 56% of @entity1 examined. A statistically significant correlation was found between the degree of @entity850 at both levels under consideration (chi2=81.452; p<0.00001; contingency coefficient CC=0.733). A significant correlation was found between the development of clinical symptoms and the severity of extra and @entity932 . The consistency between % representation of CTA-detected @entity543 , as independently analyzed by two radiologists, was higher in combined @entity11542 _MPR than in @entity11542 only (correlation coefficient R=0.9924, p<0.00001). CONCLUSIONS: There was a statistically significant correlation found between extra-and @entity7244 in @entity1 with symptoms of cerebral circulation insufficiency indicating that cervical and @entity1779 tend to occur concomitantly. Combination of @entity11542 _ MPR seemed the optimum CTA post-processing technique when evaluating the intracranial arteries.
