Tests and Services


An ultrasound uses high-frequency sound waves and a computer to create images of blood vessels, tissues and organs. Ultrasounds are used to view internal organs as they function and to assess blood flow through various vessels. Ultrasound is painless and provides much information about a child’s health.

Doctors use ultrasounds to help diagnose medical conditions and diseases. Children’s team performs nearly 8,000 ultrasounds annually, using state-of-the-art equipment. Ultrasounds are simple procedures that do not use radiation, special dyes, or anesthesia. Patients are generally comfortable during the test and the test itself requires little preparation.

How does ultrasound work?
Ultrasounds use a transducer, which is a small device that is placed over the area being examined. The device passes sound waves through the skin. These sound waves are at such a high frequency that they can not be heard by humans. The sound waves bounce off the body’s organs and tissues to create an “echo.” The transducer receives the sound waves and converts the echo to electrical signals, which are recorded on a computer monitor.

David Wessel, MD, Senior Vice President of the Center for Hospital-Based Specialties and Raymond Sze, MD, Chief of Diagnostic Imaging and Radiology are pleased to announce that the American College of Radiology’s (ACR) Commission on Quality and Safety has granted accreditation to the following diagnostic imaging programs:
-Computed Tomography
-Nuclear Medicine

Attaining the ACR Gold Seal of Accreditation is an arduous process that involves submission of physician and staff credentials, safety policies, detailed quality assurance records for each scanner, radiation dose calibrations for the ionizing radiation-producing scanners, and multiple samples of actual clinical images from each scanner. All data and images submitted are analyzed by a group of expert radiologists and medical imaging physicists who determine if the site meets the highest standards of quality and safety.

Children’s Division of Diagnostic Imaging and Radiology (Sheik Zayed campus location) achieved this high honor and is now ACR Accredited for a 3-year term. Congratulations to the faculty and staff for their commitment to high quality patient care, patient safety, and overall excellence in imaging.
