T1 weighted imaging is sensitive to slow spin motions
in tissue, and may provide information about the
macromolecular properties of tissues. Therefore clinical
application of the technique is of increasing
importance. The aim of our study was to investigate the
feasibility of T1 imaging in diagnosing cholesteatoma.
In this study, we compared the differences of average
T1 values between cholesteatoma and non-cholesteatoma
group. As a result, cholesteatoma can be distinguished
from other middle ear diseases. Although the precise
mechanism of pathogenesis is not fully elucidate, our
results will help us for a better understanding of
biological behavior in cholesteatoma.
