Ultrasonography, is a non-invasive imaging technique that allows internal body structures to be seen. Ultrasound waves are considered to be safe.
The ultrasound waves that are reflected will return as "echoes" to the probe, and are converted into an image that is displayed on the monitor, giving a 2-dimensional "picture" of the tissues under examination.
The technique is invaluable for the examination of internal organs and was first used in veterinary medicine for pregnancy diagnosis. However, the technique is also extremely useful in evaluating heart conditions and identifying changes in abdominal organs. Ultrasonography is very useful in the diagnosis of cysts and tumors.
The video scope is a instrument that uses a miniature camera and 100x magnification to view various areas. It can be used during the exam or for further diagnosis in areas that can not be seen by the naked eye. Some of the most common areas the video scope is used to examine are the ear canal and the throat, however it can also aid during surgical procedures when needed.
