Ultrasound at Griffin Hospital

Ultrasound FAQs

What is Ultrasound?

Ultrasound is an excellent imaging modality that provides visualization of different body parts, including but not limited to, liver, kidneys, breast, blood vessels, pelvic organs, and any superficial lump throughout the body. This non-ionizing and non-invasive technique helps physicians’ reach a diagnosis and treat their patients properly. Images are taken in real-time, which provide visibility of the structures inside the body, while simultaneously evaluating the blood flow. Not only does our Ivy Brook location provide easy accessibility, but is equipped with transducers that provide superior visualization of deeper organs and anatomy seen in bariatric care.

Ultrasound uses a transducer or probe held by a sonographer or technologist. A special gel is placed on the probe to insure good signal conduction and to allow the probe to be easily moved over the skins surface at various angles. The probe sends out ultrasonic sound waves at a frequency too high to be heard. When the transducer is placed at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the organs and structures within. The sound waves bounce off the organs like an echo and return to the transducer. The transducer picks up the reflected waves, which are then converted by a computer into an electronic picture of the organs or tissues under study and are displayed on a monitor.

Imaging for a clearer view

Griffin Hospital's ultrasound suite consists of two private examination rooms equipped with advanced ultrasound imaging units.

Our staff consists of highly trained, nationally certified sonographers through the American Registry of Diagnostic Medical Sonographers (ARDMS). Our sonographers are highly competent and skilled in performing abdominal, gynecological, small parts, intra-operative, vascular, and breast ultrasound examinations. Interventional ultrasonography procedures, such as biopsies and aspirations, are routinely performed. We are proud to announce that both of our ultrasound suites are accredited and recognized by the Joint Commission and the American College of Radiology (ACR). The department was awarded a three-year accreditation by the American College of Radiology for the areas of General Ultrasound, Breast Ultrasound, Gynecologic Ultrasound, Small Part Ultrasound, and Vascular Ultrasound. We ensure that each patient receives compassionate and individualized care. The Ultrasound Department offers such comforting amenities as warm blankets, the choice of music selection, and various types of aromatherapy during ultrasound examinations.

Philips iU22 Ultrasound for Pediatric imaging

This high-resolution scanner features a new level of distortion-free image display for clearer, more accurate readings by our experienced staff of technologists in pediatric imaging.

Preparation for ultrasound examinations

The Ultrasound Department at Griffin Hospital would like to provide exam preparations in order to facilitate your visit. It is our hope that this will assist you if you have any questions about preparing for your ultrasound. If you should have any further questions, please call the Ultrasound Department at (203) 732-7270.

Breast Ultrasound/Breast Biopsy/Breast Aspiration

If an ultrasound or mammogram was done at an outside facility or doctors office, please bring the films with you to your appointment.

Abdomen/Aorta/Renal Artery Doppler Ultrasound

Please do not eat, drink, smoke or chew gum for 6-8 hours prior to your examination. If you have an early morning appointment, please refrain from eating or drinking from midnight the night before. This allows the sonographer to get the clearest and most diagnostic images for interpretation. If you must take medication in the morning, drink small sips of water only.

Renal/Pelvic/Transvaginal Ultrasound

Please drink 24 ounces of water (1) hour prior to your scheduled appointment. Be sure not to empty your bladder before your test.

Thyroid/Carotid Ultrasound

Do not wear turtlenecks or high collar shirts.

As a member of a patient focused team, our department works very closely with highly skilled Radiologists, pathologists, surgeons, oncologists, state licensed mammographers, and radiological technologists who are all committed to the health and wellness of those we serve.
