Abstract:
Objective To evaluate the clinical application of the auto trigger technique with dual-source CT in cerebral and cervical vessel. Methods 35 patients were randomly divided into three groups, taking triggered threshold as 20HU,50HU and 70HU respectively, CT-values in segments of left middle cerebral artery, superior sagittal sinus, left common carotid artery adjacent to the fourth cervical vertebrate and internal jugular vein by injection at antecubital vein were all measured. Results The discrepancy of peak in artery among groups was not statistically different. It was statistically different in the same segments of vein. Conclusion CTA of cerebral and carotid arteries with the dual-source CT triggered technique can be clearly showed with 20HU as triggered threshold.
