Overview of Ultrasound

The Ultrasound department is located on the first floor of the hospital. The staff perform all modes of ultrasound to include OB/GYN, high-risk OB, abdominal, cardiology and vascular imaging. We are accredited  by the American College of Radiology.

Patient Preparation

Ultrasound preps are very basic.

Abdominal Exams: Nothing to eat or drink after midnight. Patients may take their medications with water.

Pelvic Exams: Requires a full urinary bladder. Drink 36 oz of water, one hour before your scheduled appointment time.

Obstetrical Exams:
1st trimester: 

  • Drink 36 oz. of water, one hour before your scheduled appointment time.

2nd and 3rd trimester: 

  • Patients are reminded that in the interest of space, and in order to provide a thorough and accurate exam, only two people are allowed to accompany the patient into the scan room (please no children under the age of 12). Ultrasound is very demanding exam and requires the sonographer's complete attention. For thisreason, visitors are asked to keep distractions to a minimum.

Cardiology Exams: No prep required.

Stress Echo: Nothing by mouth four hours prior to exam.

Vascular Exams: No prep required.

Frequently Asked Questions

Q- How long will the exam take? 
A- Most exams require 30 to 45 minutes (not including registration). Patients should plan on being in the department for approximately one hour. Patients having stress echos, should allow two hours.

Q- Why do I need to fast for my exam? 
A- Fasting eliminates much air in the stomach, which ultrasound does not see through. In addition many foods contract the gallbladder thus preventing visualization.

Q- Why do I need a full urinary bladder? 
A- The full bladder is used as a window to see through the bowel in the pelvis. This allows visualization of the uterus and ovaries.

Q- When will my physician receive the report?
A- Reports are generated after the Radiologist interprets the images. This is usually done on the same day as your exam. The report is dictated at this time for transcription and the report is sent out to your physician within 48 hours. Please remember that the sonographer will not be at liberty to give you a verbal report at the end of your exam. 

Q- Is ultrasound harmful? 
A- No. After many years of using diagnostic levels of ultrasound, no harmful effects have been demonstrated. For more information go to these sites on the web:
