Diagnostic Medical Sonography is an imaging modality that uses high frequency sound waves to capture and produce live images of different structures within the body.
Ultrasound can be used for a variety of reasons including the following:
Abdominal – evaluates the liver, gallbladder, kidneys, pancreas, hernias, aorta screenings for AAA and the appendix
Soft Tissue – evaluates the thyroid, lymph nodes, small superficial lumps and male genital tract
- GYN – evaluates the uterus and ovaries
- Breast – evaluates a breast lump and is often times used in conjunction with a mammogram
- Obstetrics – evaluates the presence and viability of a pregnancy as well as fetal growth and fetal anatomy surveys
- MSK – evaluates for tendonitis, plantar fasciitis, Achilles tears or ruptures and muscle tumors
- Pediatrics – Ultrasound is a safe and cost effective way to image children. It is readily available, involves no ionizing radiation, and has the ability to provide high quality images of pediatric patients.
- Abdominal – Patients must fast for 6-8 hours prior to their examination in order to eliminate the presence of bowel gas. Abdominal exams are recommended to be scheduled in the early morning.
- Sonohystogram – It is recommended that patients call to schedule the procedure on the 1st day of their cycle. It is recommended to have the procedure performed one week after menstruation to avoid the risk of infection.
Sonohysterosonography, also known as saline infusion sonography, is an ultrasound exam that uses sterile saline to rule out causes for unexplained vaginal bleeding resulting from polyps, fibroids, endometrial atrophy, endometrial adhesions/ scaring, cancerous masses or congenital defects. Sonohysterosonography is also used to investigate causes for infertility or multiple miscarriages.
Nuchal Translucency Ultrasound
Nuchal translucency testing is a sonographic exam performed to evaluate the collection of fluid under the skin, behind the fetal neck during the 1st trimester of pregnancy.
A combined 1st trimester NT screening is a noninvasive screening test for fetal Down syndrome and trisomy’s 13 and 18. The screening includes an ultrasound and maternal bloodwork, while the ultrasound evaluates and measures the amount of fluid under the fetus’s neck (NT); it also determines the presence of a nasal bone. The maternal blood sample is collected to evaluate three chemicals, beta- human chorionic gonadotropin (hCG), pregnancy associated plasma protein-A (PAPP-A) and alphafetoprotein (AFP).
An imaging modality commonly used to screen or evaluate tumors of the breast. Ultrasound uses high frequency sound waves to produce images of the inside of the breast. Because ultrasound does not use radiation, it is considered safe for pregnant or breast feeding patients.
When is a breast ultrasound performed?
Referring physicians may recommend an ultrasound for patients that are under the age of 30, are pregnant, are breast feeding or have silicone breast implants. Physicians may also recommend a patient have an ultrasound and mammogram if they feel a palpable lump on a breast exam.
