血管生成、图像融合法容积重建出血性脑血管病变的价值 postprint

Abstract: Objective To explore the value of add vessel and merge views of spiral CT volume to reproduce hemorrhagic cerebral vascular disease. Methods Using 16 -slice spiral CT volume scan of the head, Volume rendering of the 25 cases of hemorrhagic cerebral vascular disease,image of blood vessel growth and image fusion method,Analysis of the performance of the hemorrhagic cerebral vascular disease CTA image, To evaluate the strengths and weaknesses of hemorrhagic cerebral vascular disease diagnosis and treatment. Results MSCTA, 18 aneurysms, 3 AVM, and,2 cerebral CVM were found in 25 patients, The aneurysmal body and neck, parent artery and relationship with adjacent vessels and skulls were displayed clearly and exactly by MSCTA, The position, shape, sources of the feeding artery branch of the draining vein and stereochemical structure of the nidus of AVM were showed clearly The sensitivity and specificity for MSCTA of detection of SAH with were 95% and 100%,respectively Conclusion MSCTA, as a simple, fast, non-invasive, safe and reliable technique of Cerebral Angiography can take place of DSA on some degree, and be regarded as the first choice on etiological diagnose of superacute SAH.
