Abstract：Objective To explore the diagnostic value of 128-slice spiral CT three-dimensional reconstruction technique in the diagnosis of intracranial aneurysms. Methods We retrospectively analyzed the clinical data of 125 patients (134 lesions) in-tracranial aneurysms, who admitted to our hospital. Patients underwent three-dimensional reconstruction of brain CT and digital subtraction angiography ( DSA) . We compared the detection rate of intracranial aneurysms with two kinds of examination methods, and analyzed the difference between the maximum tumor diameter and the diagnosis. Results The detection rate of intracranial aneurysms was 94. 8%, lower than that of DSA (97. 0%), and there was no significant difference ( P >0. 05). The detection rate of intracranial aneurysms (5. 72 ± 2. 13) mm was slightly higher than that of DSA method (5. 68 ± 2. 08) mm. There was no significant difference ( P >0. 05). The detection rate of intracranial aneurysms of contrast agent dose, check time-consuming, inspection costs were lower than the DSA method. The difference was statistically significant ( P <0. 05). Conclusion 128-slice spiral CT three-dimensional reconstruction technique has high detection rate of intracranial aneurysms, which is non-inva-sive, intuitive, low cost and fast. It can be used as the first choice for preoperative screening and evaluation.
