In medicine, indium colloid is used for liver, spleen and bone marrow scanning. Indium DTPA was used for brain and kidney scanning. Indium Fe (OH) 3 granules were used for lung scanning. Indium Fe ascorbic acid was used for placenta scanning. In liver blood pool scanning, indium was used to deliver ferritin.

Due to its strong light permeability and conductivity, indium is mainly used to produce ITO targets (for liquid crystal displays and flat panel screens), which is the main consumption area of indium ingots, accounting for 70% of the global indium consumption.
