Corn starch with water creates a white liquid which has
generated particular interest in several groups. The
relaxation times values are close to the ones we could
have in vivo. A tube filled with water and a
concentration of 66% in volume of corn starch was
prepared. Two additional tubes, filled with agar gel and
agar gel were also added to the phantom as reference.
Corn starch solution with water displays interesting MR
relaxation characteristics, with low T2 and T2* values
and low T2/T1 ratio. As such, it could serve as a
valuable phantom for testing short T2 and T2*.
