Experience of diagnosis of 56 cerebral aneurysms cases by 16-slice spiral CTA / 中国医学装备

ABSTRACT

Objective:To evaluate the clinical value of 16-slice spiral CTA and methods of diagnosis of cerebral aneurysms.Methods: Fifty six cases of cerebral aneurysms with CTA image data were retrospectively analyzed from July 2012 to July 2014. Omnipaque (350 mgI/100 ml) as contrast agent was used in all cases with injection speed of 4.0 mL/s. The methods of VR, SSD, MIP, MPR, CPR and VE were involved in CTA images reconstruction and processing were implemented with workstation ADW4.2. The diagnosis value of cerebral aneurysms with different methods of vessel reconstruction was analyzed.Results: The location and the size of intracranial aneurysms could be clearly showed with 16-slice spiral CTA. The diagnosis time of methods VR and MIP was shortest and the mean time was 4.3 minutes and 5.1 minutes respectively. There was significant difference between the image and actual size in berry aneurysms with SSD method.Conclusion: The synthetic application of multimethod can improve the diagnostic value of 16-slice spiral CTA in cerebral aneurysms.
