Review of the diagnosis of gastrointestinal lanthanum deposition

Figure 2 Electron microscopy analysis of gastric lanthanum deposition. A: In scanning electron microscopy, deposited lanthanum is visible as bright areas; B: Deposited lanthanum is composed of aggregates of particles; C: Elemental mapping with energy dispersive X-ray spectroscopy shows that the distribution of lanthanum; D: Phosphate is identical to that of the bright areas; E: Energy dispersive X-ray spectroscopy shows presence of lanthanum (La) and phosphate elements (P).
