[Temporal bone imaging].

With the advent of high-resolution computed tomography (HRCT), diagnostic imaging has played important roles in the evaluation and management of diseases in the temporal bone. Recent advanced technology such as, multi detector-raw, sub-millimeter slice thickness (0.5 mm), high-speed rotation (0.5 sec/rot), can make more accurate and rapid examination possible. Magnetic resonance imaging (MRI) can provide additional information because of its high contrast of soft tissues. In this article, characteristic findings of several diseases in the temporal bone, such as, anomaly, cholesteatoma, cholesterol granuloma, glomus tumor and other tumors, are presented.
