At 24 weeks, magnetic resonance imaging shows just a few nascent grooves in the otherwise smooth surface of the fetal brain, according to a 2000 study in the journal Radiology.
The concentration of biomolecule adsorbed on surface could also be determined according to the resonance Angle shift.
生物分子在材料表面吸附的浓度也可以通过检测共振角度的偏移而获得。

Using functional magnetic resonance imaging (fMRI), the researchers were also able to measure the surface area of the primary visual cortex in each volunteer.
