摘要
目的探讨MSCT数字减影血管成像(MSCT-DSA)诊断颅内动脉瘤的价值。方法68例临床怀疑颅内动脉瘤者中行传统的MSCTA检查者32例,MSCT-DSA检查者36例,所有MSCTA检查均行MIP、VR、MPR和CTVE重建。结果传统的MSCTA检查对颅内动脉瘤诊断的检出率、敏感性、特异性和准确性分别为93.8%、93.8%、100%和93.8%,而MSCT-DSA者均为100%,但两者无统计学差异(P>0.05);MSCT-DSA法的瘤体邻近颅骨完全分离率为100%,高于传统的MSCTA检查(81.3%)(P<0.05);MSCT-DSA法的后处理时间为(9.3±5.4)min,短于传统的MSCTA检查[(20.6±9.7)min](P<0.05)。结论颅内动脉瘤的MSCT-DSA检查优于传统的MSCTA检查。
Objective To assess the diagnostic value of MSCT-DSA examination in the intracranial aneurysms. Methods 68 cases clinically suspected as the intracranial aneurysms were performed using the traditional MSCTA examination in 32 cases,and the MSCT-DSA examination in 36 cases. All reconstructed images were reformed by means of MIP, VR, MPR and CTVE. Results The detecting rate, sensitivity, specificity and accurate rate of the traditional MSCTA were 93.8% .93. 8%. 100% and 93. 8% respectively, and the MSCT-DSA examination all were 100% （P〉0. 05）. The complete isolating rate for detection of aneurysms with MSCT-DSA examination was 100%, with high ratio by this method than 81.3% by the traditional MSCTA examination （P〈0. 05）. The post-processing time MSCT-DSA examination was （9. 3 ± 5.4） minutes, and the traditional MSCTA was （20. 6 ± 9. 7） minutes （P〈0. 05）. Conclusions The MSCT-DSA is superior to the traditional MSCTA in the diagnosis of intracranial aneurysms.
