2、 of Internal Carotid Aneurysms ABSTRACT Objective: To evaluate the clinical application value of multi-detection CT angiography (MDCTA) in the preoperative diagnosis and assessment of Internal Carotid Aneurysms. Methods

3、: Collect 62 patients which conformed having Internal Carotid Aneurysms by DSA or surgeries and analyze their preoperative MDCT conventional scan and MDCT angiography data that generated from GE 64 detection Lightspeed V

4、CT. All of these data was sent to advantage workstation (AW4.3) reconstructed with multi-planar reformation (MPR), maximum intensity projection (MIP), volume rendering (VR) and stacking technique of VR. Compliance rate f

5、or aneurysm detection with MDCT angiography was calculated by using DSA or surgical as the reference standard. While, analyzing the size, neck, body， location and surroundings of aneurysm compared with DSA or surgical fi

7、mm. Of 70 aneurysms, 15 aneurysms were smaller than 3 mm, 22 aneurysms were 3–5 mm, 26 aneurysms were5–10 mm, and 7 aneurysms were bigger than 10 mm in maximal diameter. A total of 68 intracranial aneurysms were detected

8、 by MDCTA in these 62 cases, Compliance rate for aneurysm detection with MDCT angiography was 97.1%，two aneurysms were missed which size were smaller than 3 mm that located on the origin part of the posterior communicati
