MR lymphangiography in lymphedema

Abstract

Lymphedema is a chronic disorder, defined as progressive and excessive accumulation of protein-rich fluid, inflammation and fibrosis in the interstitial space, resulting from impaired lymphatic drainage. It is vulnerable to misdiagnosis and has been badly reputed as an incurable disease. Nowadays, the lymphovenous anastomosis (LVA) is microsurgical technique for bypassing the obstructed segment of the lymphatic pathway into the venous system. MR lymphangiography (MRL) is an advance imaging technique using 3D volumetric contrast-enhanced MR angiography with high temporal and spatial resolution, which can evaluate both anatomy and function of the lymphatic system. It is a quick less invasive imaging technique, which aids in diagnosis, preoperative evaluation and follow up. For the experience and technical detail of MRL in PSU will be described in this article.
