    • Abstract
  • Objective: To evaluate the application values of multislice CT angiography(MSCTA)in the diagnosis of cerebral aneurysms.Materials and Methods MSCTA were performed in 31 patients with cerebral aneurysms confirmed by DSA or operation.CTA were processed with maximum intensity projection(MIP),volume rendering(VR)and curved planar reformation(CPR).20 patients were performed operation and 11 patients were performed operation.Results: 36 cerebral aneurysms were found in 31 patients.29 cases were solitary and 2 cases were multiple(5 cerebral aneurysms).33 cerebral aneurysms were found in MSCTA,but 1 was misdiagnosed.32 cerebral aneurysms were diagnosed correctly by MSCTA,and 4 were missed on the MSCTA.The accurate rate was 97%(32/33)and sensitivity was 89%(32/36).The diameter were between 3~35 mm with average size of 8mm on MSCTA images.The location,size and appearance of cerebral aneurysms showed in MSCTA images were in accordant with the result of DSA and operations.Conclusion: MSCTA can display clearly the location,size and appearance of cerebral aneurysms accurately and objectively.MSCTA and DSA or surgery have high diagnose accordance rate.It plays an important role in the diagnosis of the disease.
