What is Ultrasonography?

Ultrasonography, also called ultrasound or sonography, is a technique that uses high frequency sound waves to produce pictures of various organs and tissues in the body. The sound waves are produced by a hand-held device called a transducer. Much like sonar, the sound waves bounce off the organs of the body and are converted into pictures. Ultrasound is a highly sophisticated, safe, and painless technique.

Ultrasonography can provide your doctor with information about your internal organs, such as the liver, gallbladder, and kidneys. It can be used to look at arteries and veins. One of the more well known uses of ultrasound is for imaging the unborn child.

How do I prepare for my ultrasound examination?

If you are scheduled for an abdominal exam, you will be instructed not to eat or drink for at least six hours prior to your testing. If you are scheduled for a pelvic or obstetrical exam, you will be instructed to drink 40 ounces of clear fluid one hour prior to your exam and not to urinate. While uncomfortable, a full bladder helps to enhance the ultrasound image of the pelvic organs. If your bladder is not full at the time of the exam, the test may be delayed while you drink more water. No preparation is needed for vascular exams.

What can I expect during my ultrasound exam?

For some exams you will be asked to change into a gown. The sonographer, a registered technologist with specialized training in ultrasound, will discuss the procedure with you and answer any questions you might have.

You will lie on an examination table next to the ultrasound scanner. A special gel will be applied to the area of your body to be examined. The sonographer will then take the transducer and slowly guide it across your skin in the area to be examined. The sonographer will watch the corresponding image which appears on a TV monitor. Pictures will be taken periodically for further study. The exam takes approximately 20 to 60 minutes.

The sonographer will show your examination to the radiologist, and additional images will be obtained if needed.

What will happen following my ultrasound exam?

After your ultrasound exam, you may resume your normal activities, diet, and medications unless instructed otherwise by the technologist or your doctor. There are no after effects from the exam.

Your examination will be reviewed by the radiologist after the exam has been completed. If you choose OnSite Results, your preliminary results will be given to you before you leave our office. Your physician will be sent a detailed final report by fax or mail.

Our Patients Tell Our Story Best

I am going to contact my physician and tell him to start referring patients to Metro. Since many people now have high deductibles, the cost for my exam was 1/3 the cost of just the technical component at the hospital. I also didn't have the issue of parking and waiting like I have experienced in the past with hospital based radiology departments.

- West County Patient

I could not have had a better experience today. I came in to your center extremely nervous, and your staff made me feel like family before I left. This was such a pleasant experience; I have already told a dozen of my co-workers to visit your location if they ever need your services.

- South County Patient

I only go to Metro Imaging, even when the doctor wants me to go to his or her radiology department. Onsite results plus VIP service are prime reasons why I always come to Metro imaging for my radiology tests.

- North County Patient

I had been having my mammograms at a hospital for 20 yrs & decided to go to your facility this time since you are doing 3D at no additional cost to the patient. I am so glad I chose Metro Imaging.

- St. Peters Patient

It was a great experience. I was there for a routine x-ray and didn't have an appointment. I was only there about 35 minutes, what a pleasant alternative to going to the hospital for an x-ray, not to mention the cost savings! I will always choose Metro Imaging over the hospital.

- Richmond Heights Patient

Metro does an EXCELLENT job. I will never return to the hospital-based system again. I recommend Metro to all of my friends.

- St. Peters Patient

I have been in medicine for over 20 years and I have never seen or used a better facility. Efficient, professional, courteous, lower cost – better than any hospital I have seen, and I have used all in the County area as a patient and physician. I have sent my patients to several facilities, outpatient and hospital, nothing better. So all in all, Metro is the best in town for certain.

- West County Patient

OnSite Results eliminates what could be days of uncertainty while waiting for a follow-up from a physician. I received my results within minutes of finishing the exam.
