Ultrasound Imaging

 

Ultrasound

Ultrasound imaging, also called sonography, is a painless and noninvasive method of ‘seeing’ inside the human body through the use of high-frequency sound waves. As the sound passes through the body, echoes are produced that can be used to identify how far away an object is, how large it is, and how uniform it is. Chances are, someone you know has had an ultrasound exam. In fact, ultrasound is the most utilized form of diagnostic imaging  after x-ray.

IWhile much of the general public is familiar with the use of ultrasound during pregnancy, many people are unaware that an ultrasound examination can be used to examine other parts of the body including the prostate, breast, brain, eyes, tendons and arteries. In its two-dimensional form, ultrasonography is used extensively in the abdomen (kidneys, liver, and gallbladder), female pelvis (both obstetrical and gynecological), and for cardiac diagnosis. Another type of diagnostic ultrasound, Doppler, is used in vascular diagnosis to assess blood flow.

The ultrasound scanner consists of a computer, a video display screen and a transducer -- a small hand-held device that is pressed firmly against the skin. Sound waves produced by the transducer cannot penetrate air, so the technologist will spread a lubricating gel on the area being scanned to eliminate air pockets between the transducer and the skin. The sound waves are then recorded and displayed as a real-time visual image on the nearby screen. No radiation is involved in ultrasound imaging.

 

Commonly asked questions:

How should I prepare for my Ultrasound?

The following are the necessary preparations for an Ultrasound of the gallbladder: No food or liquids other than water for 6-8 hours prior to your exam. You may take your medications, as usual. Pelvic Exam: It will be necessary to have a full bladder prior to your exam. It is recommended to drink approximately 32 ounces of fluid 1 hour before your exam.

*    All other Exams:  No preparation is necessary.

 

What can I expect during my visit?

Upon arrival, you will be asked to complete some personal information forms for insurance and internal record purposes. The technolo­gist will explain the procedure to you and answer any questions you may have. During the exam the technologist will apply a clear gel to the area to be examined. The purpose of the gel is to eliminate air between the transducer and your body. You may be asked to wait after the exam while the technologist and the radiologist review the images. 

 

Is the Ultrasound safe?

Yes, high frequency sounds waves are undetectable by the human ear. Ultrasound utilizes sound waves which cause no side effects.

 

How long does the Ultrasound take?

It depends on the type of Ultrasound exam. The pelvic Ultrasound takes about 15 minutes. Abdominal Ultrasounds take 15-30 minutes and vascular Ultrasounds take 30-45 minutes.

 

Can I eat before my Ultrasound?

Yes, unless the Ultrasound is of your gallbladder. You should not eat 6 hours prior to a gallbladder Ultrasound. Medications may be taken with the necessary water.
