The diagnostic value of magnetic resonance thoracic ductography in right thoracic duct / 实用放射学杂志

ABSTRACT

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.
