A radiological method with which, following the injection of lymphotropic and radio-opaque contrast medium (Lipiodol ultrafluid, see), into lymphatic circulation, the general structures of lymphatics, their morphology, and anomalies, if any, can be displayed. This technique developed by Kinmonth in 1955 is carried out in three steps: identification of lymphatic structures by means of a vital stain (Blue Patent Violet, see BPV); surgical isolation of detected collectors; incannulation of collectors with injection of liposoluble contrast medium directly into the collectors or with support from a spiral CT.
