An ultrasound uses high-frequency sound waves and a computer to create images of organs, blood vessels, soft-tissues, or of pregnancy. These sound waves are transmitted to the body through a transducer. A warm gel is applied to the skin for better transmission and reception. The sound waves return as echoes and are recorded as images on a computer monitor. Ultrasound is commonly used to perform obstetric, breast and thyroid scans, and to diagnose diseases of the blood vessels or to determine causes for abdominal and pelvic pain.
Ultrasound Scans are performed 24 hours a day, seven days a week for inpatients and Emergency Department patients. Outpatient examinations are done on a scheduled basis only: Monday through Friday, 7:15 a.m. to 7 p.m. and Saturday, 8 a.m. to 12 noon. On-site or on-call sonographers are available for all other hours.
