Giddiness is common, but confusing symptom. The evaluation requires patience and thorough knowledge of various systems. Causes can vary from just being functional to structural. It is here where imaging plays a significant role. Prior to advent of computed tomography (CT), pleurodirectional tomography was used to evaluate patients with temporal bone disease. Polytomography provided excellent visualization of bony abnormalities but suboptimal delineation of soft tissue lesions. High resolution CT currently provides improved detection of bony abnormalities compared to polytomography. CT is still the procedure of choice for detection of osseous abnormalities of the temporal bone. CT lacks the capability to characterize detected soft tissue abnormality. The identification as well as characterization of soft tissue abnormalities, as inflammatory or neoplastic within the temporal bone is far easier on MR than on CT because of the lack of bony artefact. It has now been 25 years since the first magnetic resonance (MR) images were produced. Just about the time we think MRI has settled down and we begin to gather clinical experience worldwide, new software or hardware comes along, making previous techniques all but obsolete.

It was thought appropriate to bring out detailed issue dedicated to this common but complex problem, the diagnosis and treatment of which can be incomplete or unsatisfactory, if not understood properly.

The purpose of this issue is threefold -

1. To demonstrate normal appearances.

2. To illustrate the imaging appearance of common lesions responsible for giddiness.

3. Indicate those instances where imaging plays role in diagnosis and patient management in a case of-giddiness.

The future of imaging in medical diagnosis and medical research is bright one indeed, and this issue goes a long way towards accurately presenting the role of imaging in diagnosis and management of giddiness.
