摘要
目的 探讨基于笛卡尔采集的K空间共享三维容积快速动态成像(DISCO)技术在儿童脉管畸形的应用价值.方法 回顾性分析49例脉管畸形患儿的影像学资料.患者入院后均行DISCO动态对比增强磁共振成像(DCE-MRI)检查,以病理结果为标准,评价DISCO DCE-MRI检查在诊断儿童脉管畸形中的准确率.结果 49例患者中5例为全身多部位病变,其余均为单发,共57个病变,经病理证实,毛细血管畸形(CM)7个,淋巴管畸形(LM)10个,静脉畸形(VM)16个(其中2个伴静脉石、1个伴血栓),动静脉畸形(AVM)15个(其中6个伴动静脉瘘),CM+LM+AVM 9个,DISCO DCE-MRI的诊断符合率分别为 100％、100％、93.7％、100％、88.9％,与病理学结果比较无统计学差异(P＞0.05).结论 DISCO技术有助于儿童脉管畸形的准确诊断及分类,可作为临床诊疗的依据,具有重要的应用价值.
Abstract
Objective To explore the role of differential subsampling with cartesian ordering(DISCO)of Pediatric Vas-cular malformations.Methods A retrospective analysis was performed in 49 patients with venous malformations who un-derwent DISCO contrast-enhanced magnetic resonance angiography(CE-MRA).The diagnostic accuracy of DISCO CE-MRA in Pediatric Vascular malformations was examined based on pathological results.Results 5 of the 49 patients had systemic multisite lesions,and the rest were solitary.A total of 57 lesions were identified.There were 7 cases with capillary malformation(CM),10 with lymphatic malformation(LM),16 with venous malformation(VM,2 with venous stones and 1 with thrombosis),15 with arteriovenous malformation(AVM,6 with arteriovenous fistula),9 with CM-LM-AVM.The diag-nostic concordance rates of DISCO CE-MRI were 100％,100％,93.7％,100％and 88.9％,respectively.There was no sig-nificant difference in accuracy between the DISCO CE-MRI examination and pathological results(P＞0.05).Conclusion The DISCO CE-MRI has important application value for the accurate diagnosis and classification of vascular malformations in children,which can be used as the basis for clinical strategy.
