Imaging the central conducting lymphatics: initial experience with dynamic MR lymphangiography.

Purpose: To describe a dynamic magnetic resonance (MR) lymphangiography technique after intranodal injection of gadolinium-based contrast agent and to assess its feasibility for evaluation of the central conducting lymphatics (CCL) in patients with pathologic disorders that involve the CCL.

Materials And Methods: A retrospective evaluation of experience with the dynamic MR lymphangiographic technique in six consecutive patients was performed after institutional review board approval. Written informed consent for the percutaneous procedure was obtained from the patient, parent, or the legally responsible guardian.
