CT血管造影与磁共振血管成像诊断脊髓血管畸形的临床应用
CT angiography and magnetic resonance angiography visually showing spinal vessels and spinal involvement in diagnosing spinal vascular malformations
摘要
Abstract
Objective To explore the clinical application of CT angiography(CTA)and magnetic resonance angiography(MRA)in the diagnosis of spinal cord vascular malformations.Methods This prospective study included 30 patients with spinal cord vascular malformation diagnosed and treated in our hospital from February 2020 to December 2022 as the experimental group.In addition,30 patients without spinal vascular malformation who underwent vertebra MR Scan plus enhancement were selected as the control group.Contrast enhanced magnetic resonance angiography(CE-MRA)sequence and reconstructed spinal vascular CTA were performed on all enrolled subjects.The diagnostic consistency of CE-MRA sequence and reconstructed spinal vascular CTA was compared,and the combined diagnostic efficacy of CE-MRA sequence and reconstructed spinal vascular CTA was analyzed.Results There was no statistical significance in dural arteriovenous fistula,spinal arteriovenous malformation,and perimedullary arteriovenous fistula in CE-MRA and CTA examination(P>0.05).In the analysis of fistula,there was no statistical significance in the display of supplying artery and fistula in CE-MRA and CTA examination(P>0.05).CE-MRA had a good consistency by compare with the gold standard,with a kappa value of 0.758,and CTA had a good consistency by compare with the gold standard,with a kappa value of 0.881.The sensitivity of CE-MRA and CTA combined diagnosis were significantly higher than that of the single detection.ROC curve analysis showed that the area under the curve of CE-MRA and CTA combined diagnosis was significantly higher than that of single detection(P<0.001).Conclusion In the diagnosis of spinal cord vascular malformations,the combined diagnosis of CTA and CE-MRA can significantly improve the diagnostic efficiency of patients,and can be used as an important basis for clinical diagnosis.关键词
