Best Investigation of choice for a lesion of the temporal bone is which of the following?: (A) X-ray, (B) USG, (C) CT, (D) MRI
Answer is C. CT scan is preferred over MRI to visualize the bony architecture. Thus any lesion in the temporal bone is characterised by a CT scan. The extent of osseous destruction brought about by the lesion is visualized in a multi-planar CT.
