MR胸导管成像诊断右位胸导管的价值

目的 评价磁共振胸导管成像(MRTD)诊断右位胸导管的价值.方法 回顾性分析MRDT资料,总结右位胸导管的检出率并与核素淋巴显像及直接淋巴管造影、手术所见相对照.结果 连续1547例MRTD检查中共检出右位胸导管12例,检出率0.78%.其中1例合并全内脏反位,1例合并右位主动脉弓.12例患者均同时行核素淋巴显像,核素淋巴显影明确诊断4例.4例行直接淋巴管造影者均可见右位胸导管.7例接受右位胸导管粘连松解术.结论 MRTD可以无创性的诊断右位胸导管,为外科手术提供客观依据,其检出率及诊断准确性高于核素淋巴显像.

The diagnostic value of magnetic resonance thoracic ductography in right thoracic duct

Objective To evaluate the effect of magnetic resonance thoracic ductography (MRTD)in the diagnosis of right thoracic duct.Methods MRTD data were analyzed retrospective,and the detection rate of right thoracic duct was summarized and compared with that of lymphoscintigraphy,direct lymphangiography and operation.Results 12 cases of right thoracic duct were detected in 1547 cases of MRTD.The detection rate was 0.78%,in which 1 case was complied with total internal organs inversion,and 1 case with right aortic arch.Lymphoscintigraphy were performed in all 12 cases and right thoracic duct were detected in 4 cases.Direct lymphangiography were performed in 4 cases and right thoracic duct were observed in all of them.7 cases of them received right lum-bar duct adhesiolysis.Conclusion MRTD is a noninvasive method for diagnosis of right thoracic duct,which providing useful guid-ance for surgical operation.Its detection rate and diagnostic accuracy are higher than those of lymphoscintigraphy.
