Understanding Ultrasound
What is Ultrasound?
Ultrasound uses high frequency sound waves to "see" the internal organs in your body. Ultrasound does not use x-rays; and is generally painless and non-invasive. There are no known dangers or side effects associated with the use of ultrasonography. It images soft tissue densities and discriminates them well; detects tumors (cystic vs. solid) and lesions, gallstones, and kidney stones; and images blood flow.
Transmission gel is applied to the area of your body being imaged. The transducer, a hand-held, microphone device, is rolled over the part of the body being imaged and sends a signal that processes the data and produces the ultrasound image.
You also may pre-register online for your ultrasound. If you choose not to, arrive at the hospital 30 minutes before your scheduled exam time to complete the registration process.
Each ultrasound has required preparations. The most frequently performed exams with their preps are listed. If instructions are not listed, your physician will inform you about your exam or you may phone Baptist Health Paducah's diagnostic imaging department at (270) 575-2600.
Abdomen
Clear liquids for dinner the night before. No carbonated beverages. Nothing to eat or drink after midnight the night before. The exam takes 30 to 45 minutes.
Aorta
Same prep as abdomen. The exam takes 15 to 30 minutes.
Gallbladder
Same prep as abdomen. The exam takes 20-40 minutes.
Obstetrical
A full bladder is necessary. Drink 32 ounces of liquid one hour before your scheduled exam time and do not empty your bladder. During the first three months of pregnancy, a vaginal ultrasound is also performed (see Pelvis below). The exam takes 45 to 60 minutes.
Pelvis
A full bladder is necessary. Drink 32 ounces of liquid one hour before your scheduled exam time and do not empty your bladder. Our routine exam may include two studies, one performed externally and one with a vaginal probe. The vaginal probe is slightly larger than a tampon. This probe is inserted into the vagina with very little discomfort. Both exams take 30 to 45 minutes.
Important Information
Your ultrasound exam must be ordered by a physician. The physician's office will make the appointment for you with our department. If you need to cancel your appointment, please call us at (270) 575-2600.
