A case series of thoracic dynamic contrast-enhanced MR lymphangiography: technique and applications

Dynamic contrast-enhanced magnetic resonance lymphangiography is a radiation-free, high spatial resolution technique which is increasingly used to evaluate thoracic lymphatic disorders and for pre-procedural planning. DCE has the added advantage of allowing dynamic real-time evaluation of lymphatic flow. It can be employed to investigate commonly encountered clinical situations such as recurrent pleural effusions following trauma, thoracic duct injury after thoracic surgery, and exclude diseases and congenital malformations of the thoracic lymphatic system. The imaging procedure and protocol are detailed in this case series to highlight the application of dynamic contrast-enhanced magnetic resonance lymphangiography in everyday practice and its importance to guide surgical planning.
