Ultrasound scanning, often referred to as sonography, is a method
that obtains images of internal body organs through the use of
high frequency sound waves which are recorded and displayed as
images on a monitor. Images are captured in
real time and therefore show movement of internal tissue, body
organs, blood flows and heart valve functions and the condition
of embryo and fetus in pregnant women.
Ultrasound is used to diagnose multiple
body parts to identify palpable masses, fibroids, kidney stones,
causes of uterine bleeding and other conditions. Carotid ultrasound
may show plaques that narrow the carotid artery and limit
the flow of blood to the brain.
Ultrasound is non-invasive and involves no radiation.
Ultrasound of the abdomen requires the patient to fast 6
hours prior to the examination. Transabdominal/transvesical
ultrasound of the pelvis requires the patient to drink several
glasses of water approximately 30-45 minutes before the examination. Most other
ultrasound procedures require no preparation.
Park Avenue Radiologists offers ultrasound-guided fine needle
aspiration and core biopsy, in addition to MRI and CT-guided
biopsy, as medically indicated.
A cytopathologist is at our facility on a weekly basis which ensures tissue sampling adequacy at the time of biopsy. Our
experience in ultrasound-guided thyroid biopsy is unsurpassed,
given the close cooperation of our pathologist with the
have published some of the largest series of thyroid biopsies
available. Our ultrasound guided biopsy also
of course involve breast, liver, and other organ systems.
