Lymphoma is a cancer of a type of white blood cells called lymphocytes. The increase in resistivity in a malignant lymph node is attributed to increased cellularity within an infiltrated lymph node. ![]() Shape: round, long axis:short axis 0.8, PI >1.5Īberrant vessels: displaced parent vessels, subcapsular vasculature, non-perfused areas, non-tapering vessels Gray scale parameters that favor malignancy Several gray scale and color Doppler features favor malignancy in a lymph node 1,7-9.
