T1- and T2-weighted MRI images of the denatured egg-white.

Planned (dots) and evaluated (squares) locations of the guide tube penetration entry point and iron deposits are added in blue and red, respectively. Due to the higher resolution and signal quality, T2-imaging was used for precise localization of iron deposits and guide tube penetration marks. In A, the electrode tract connecting the two squares can be identified. A is a T2-weighted image; B is a T1-weighted image. A & B were taken after the iron deposition.
