Abstract
Magnetic resonance lymphography (MRL) without contrast injection is a non-invasive imaging technique for exploring the lymphatic system. This method is directly based on the principles of magnetic resonance cholangiopancreatography (MRCP). We will also briefly discuss the technique of magnetic resonance lymphography with injection of water-soluble contrast agent, Lipiodol, or gadolinium, which is an interesting but still marginal technique.
Magnetic resonance lymphography without contrast injection is a precise, non-invasive, and promising method for studying the lymphatic system. It provides detailed anatomical and pathological information, essential for the diagnosis and management of patients with lymphedema or other lymphatic disorders. Its local optimization and adaptability to different anatomical regions make it a valuable diagnostic tool, offering a safe alternative to traditional invasive techniques. Magnetic resonance lymphography with contrast injection—whether using a water-soluble contrast agent, Lipiodol, or gadolinium—remains an extremely interesting but still relatively uncommon technique. Its primary indication is the detection of leaks, particularly after iatrogenic trauma to lymphatic vessels, such as injury to the thoracic duct during mediastinal surgery or injury to the retroperitoneal lymphatics during lymph node dissection.
