Diffusion-weighted image (DWI)-thermometry is one of the
most clinically applicable approaches among some
magnetic resonance methods. The DWI-based method
calculates the temperature of cerebrospinal fluid based
on diffusion coefficient of the lateral ventricles.
However, the technique is relatively recent and
insufficient yet in its analysis. We, therefore, need
further evaluation. The results revealed that lateral
ventricular (LV) temperature measurement was
successfully performed using DWI-thermometry, slice
thickness had significant effect on the calculation of
LV temperature, and thinner slice thickness was
considered to produce better results than the thick
slices. Also we found that LV temperature would change
with tympanic temperature.
