目的:探讨基于64排螺旋CT多平面重建(MPR)技术在急性主动脉夹层患者中的诊断价值.方法:选取医院2021年2月~2022年9月收治的40例疑似急性主动脉夹层患者,全部患者均行64排螺旋CT MPR技术检查,并行主动脉数字减影技术(DSA)检查,将DSA检查结果作为"金标准",分析64排螺旋CT MPR技术对急性主动脉夹层患者的诊断效能.结果:40例疑似急性主动脉夹层患者经DSA检查31例确诊,占77.50%;依据DSA诊断"金标准",64排螺旋CT MPR技术对急性主动脉夹层诊断灵敏度为93.55%(29/31)、特异度为88.89%(8/9)、准确度为92.50%(37/40)、阳性预测值为96.67%(29/30)、阴性预测值为80.00%(8/10),且与DSA检查结果一致性好(Kappa=0.793);64排螺旋CT MPR技术检查与DSA检查急性主动脉夹层Debakey分型、累及区域、伴有钙化与血栓特征对比,差异无统计学意义(P>0.05).结论:64排螺旋CT MPR技术对急性主动脉夹层患者有较高诊断灵敏度、特异度、准确度,且可鉴别疾病Debakey分型、累及区域、伴有钙化与血栓特征.
Diagnostic Application of 64-Row Spiral CT in Patients with Acute Aortic Dissection
Objective:To investigate the diagnostic value of 64-row spiral CT multiplane reconstruction(MPR)technology in patients with acute aortic dissection.Methods:All 40 patients with suspected acute aortic dissection admitted to the hospital from February 2021 to September 2022 were examined by 64-row spiral CT MPR,aortic digital subtraction(DSA),DSA results as the "gold standard",and the diagnostic efficacy of 64-row spiral CT MPR in patients with acute aortic dissection was analyzed.Results:Among the 40 suspected patients with acute aortic dissection,31 were diagnosed through DSA examination,accounting for 77.50%;According to the "gold standard" of DSA diagnosis,the sensitivity of 64-row spiral CT MPR technology for the diagnosis of acute aortic dissection is 93.55%(29/31),specificity is 88.89%(8/9),accuracy is 92.50%(37/40),positive predictive value is 96.67%(29/30),negative predictive value is 80.00%(8/10),and it is consistent with the results of DSA examination(Kappa=0.793);There was no statistically significant difference(P>0.05)between the 64-row spiral CT MPR technique and DSA examination in the Debakey classification,affected areas,accompanied by calcification and thrombus characteristics of acute aortic dissection.Conclusion:64-row spiral CT MPR technology has high diagnostic sensitivity,specificity and accuracy in patients with acute aortic dissection,and can identify Debakey classification,involvement area,calcification and thrombosis.
