Diagnostic Ultrasounds

It won't be far fetched to say that diagnostic ultrasound has revolutionized the medical field. Diagnostic ultrasound is being used literally in all hospitals and clinics around the world. Diagnostic ultrasound imaging is based on the principles involved in the sonar which is used by fishermen, ships and even bats. Whenever a sound wave strikes an object, it bounces backwards or in other words echoes. By measuring these echo waves it is possible to measure the distance of the object, its size and its consistency. The consistency factor here means finding out whether the object is filled with fluid or a solid or a combination of both.

Diagnostic ultrasound is extensively used in medicine to detect changes function and appearance of organs or tissues. In the case of a diagnostic ultrasound examination, a device called transducer is used. This device sends the sound saves and also records the echoing waves. When a transducer is pressed against the skin, it actually directs a stream of waves into the body. These sound waves then bounce off the internal organs and the transducer in turn record tiny changes in the sound. These waves are instantly measured and displayed on a computer. The live images are generally recorded on videotapes along with some still images. For most of the diagnostic ultrasound exams, the patient is placed face-up on an examination table which can be moved or tilted. A clear gel is then applied on the area of the body which needs to be examined. The gel also helps in getting the transducer make a secure contact with the body and eliminate all air pockets between the transducer and the skin.

The sonographer then presses the transducer against the skin and also sweeps it back and forth over the area to be studied. When the diagnostic ultrasound examination is complete, the patient is usually asked to wait till such times the images are reviewed. In most of the cases the sonographer is able to review the images in real time too and in such cases the patient can be released immediately. Diagnostic ultrasound procedure is easy and painless, most of the times. Only in case of a scan being performed over an area of tenderness would you fell some minor pain. After a diagnostic ultrasound exam, you can resume your normal activities.

A qualified physician specially trained to interpret radiology examinations would analyze the images and share the results with you. Career opportunities are plenty for anyone who has completed a program in diagnostic ultrasound. The trend is also expected to continue in the immediate future.
