BACKGROUND AND PURPOSE:Previous reports have shown that DWI is useful in detecting cholesteatoma. SS-EPI is the most widely used DWI technique. However, SS-EPI may have susceptibility artifacts due to field inhomogeneity in the imaging of the temporal bone region. Our purpose was to prospectively evaluate the advantage of MS-EPI for the diagnosis of middle ear cholesteatoma by comparing it with SS-EPI.

Vertebroplasty can maintain vertebral height and wedge angle and spinal canal size at least 1 year after treatment.

We conclude that there is no correlation between isolated small LSCC and SNHL.

This is to report arterial spin-labeling (ASL) regional cerebral blood flow (rCBF) mapping findings in a case of corticobasal degeneration (CBD). A 68-year-old man gradually developed limb-kinetic apraxia, myoclonus, and rigidity in the left hand and was diagnosed as having CBD. Magnetic resonance imaging and single photon emission computed tomography revealed atrophy and decreased blood flow, respectively, in the right hemisphere, findings that were compatible with CBD. In addition, ASL rCBF mapping demonstrated asymmetrical hypoperfusion areas in locations typical for CBD, proving its potential usefulness for routine clinical differential diagnosis.
