Unmatched expertise in pelvic ultrasound
While an MRI is an excellent tool, often a skilled radiologist can accurately make a diagnosis with ultrasound alone.

Seattle Ultrasound performs more pelvic ultrasounds than any facility in the Seattle metropolitan area. With the experience and dedication of our expert staff, we rarely need correlative imaging for a diagnosis. This can save patients both time and money; and it can alleviate much of the stress associated with additional testing and the wait time for the subsequent results.


State-of-the-art 3-D imaging technology
Our internationally recognized specialists utilize state-of-the-art imaging technology, including 3-D ultrasound, to meet the needs of our patients. 3-D ultrasound has many advantages over other types of imaging, and can be diagnostic for gynecologic issues including adenomyosis, embedded intrauterine devices and septate uterus.


Fetal Echocardiography
A fetal echocardiogram is a highly detailed ultrasound done to evaluate the structure and function of a baby’s heart. A fetal echocardiogram is typically recommended when:

  • A routine ultrasound indicates a potential abnormality with the heart
  • Genetic testing has revealed an abnormality
  • A baby’s parent or sibling has a congenital heart defect
  • The mother already had a condition before pregnancy, such as diabetes or lupus

Biophysical profile (BPP)
A biophysical profile (BPP) is a simple, noninvasive test that is usually done during the third trimester to evaluate a baby's well-being and to ensure that he or she is getting enough oxygen in the womb. Typically done after 32 weeks of pregnancy, the BPP consists of a targeted ultrasound done in conjunction with a non-stress test. The ultrasound is used to measure a baby's movement, muscle tone, breathing and amniotic fluid levels within the womb. The non-stress test is a separate part of the evaluation which measures a baby's heart rate using an electronic fetal heart monitor. The BPP may be repeated once or twice a week during the last few weeks of pregnancy until the baby is born to allow doctors to assess a baby's health and responsiveness and determine if he or she needs to be delivered sooner than planned.

Detailed Fetal Anatomic Ultrasound Survey
A detailed fetal anatomic ultrasound survey is an anatomy scan routinely offered during the second trimester of pregnancy, usually between 18 and 22 weeks of pregnancy. The test checks to see that a baby is developing normally and looks at a number of things, including:

  • The size of a baby
  • A baby's heart, brain, bones, limbs and internal organs
  • The position of a baby, umbilical cord and placenta
  • The amount of fluid around a baby

The ultrasound also provides an opportunity for the expectant parents to learn a baby's sex should they choose to.

Nuchal Translucency (NT) Ultrasound
A nuchal translucency ultrasound is an early-monitoring screening done between the 11th and 14th week of pregnancy. The purpose of a nuchal translucency ultrasound is to measure the amount of fluid at the nape of a baby’s neck to help assess his or her chance of having a chromosomal condition such as Down syndrome.

The test also provides an early evaluation of fetal anatomy which can help predict the likelihood of structural birth defects, such as congenital heart problems, can confirm accurate dating of the pregnancy, and detect and evaluate multiple fetuses (twins, triplets, etc.).

Targeted or Limited Ultrasound
A targeted or limited ultrasound is ordered when it is necessary to look at a specific element, such as amniotic fluid, placental or a specific part of a baby.


Doppler Flow Ultrasound
A Doppler flow ultrasound provides additional evaluation using a special type of ultrasound called color duplex Doppler or Doppler flow. A Doppler flow ultrasound measures the flow of blood in a baby's body and flow to the uterus and placenta. This allows the doctor to evaluate a baby's health and ensure that he or she is getting enough oxygen and nutrients from the placenta. The Doppler flow ultrasound is most often used during the third trimester of pregnancy in high-risk situations, including:

  • Low amniotic fluid levels
  • Twins sharing a placenta
  • A baby that is small for gestational age
  • Rh-incompatibility

3-D Ultrasound
A 3-D ultrasound is used to evaluate a suspected abnormality identified during a standard ultrasound. The resulting 3-D images give the doctor an additional tool to make an assessment in order to confirm a diagnosis.

Abdominal Ultrasound
An abdominal ultrasound can be used to evaluate and diagnose disease in most abdominal organs with exception of the intestines. It is most frequently used in cases of unexplained abdominal pain. Examples of diseases that can be detected include gallstones, tumors and liver pancreatic and kidney diseases.

Kidney Ultrasound
A kidney ultrasound can detect a wide variety of issues including stones, obstructions of urine flow, tumors, congenital cystic diseases, and evaluate kidney size.

Thyroid Ultrasound
A thyroid ultrasound is an imaging procedure used to detect a wide variety of thyroid diseases and is usually combined with blood tests to evaluate thyroid function. One of the most frequent indications for thyroid ultrasound is a physical exam suspecting a thyroid nodule. Ultrasound can be used to perform a thyroid biopsy on a nodule that is suspicious for cancer.

Pelvic Ultrasound
A pelvic ultrasound provides very high resolution images of the uterus and ovaries and surrounding pelvic tissues. It is most frequently performed with a combination of imaging from the lower abdomen and intravaginal imaging with a specially designed transducer.

Follow-Up or Complete OB Ultrasound
A follow-up or complete OB ultrasound is an evaluation that is targeted to answer specific questions, such as fetal growth or complex anatomical abnormalities. Because the evaluation is tailored to answer a specific clinical question it can be different for each patient.

Amniotic Fluid Index Ultrasound
An amniotic fluid index (AFI) ultrasound assesses the amount of amniotic fluid surrounding a baby in the uterus. Too much fluid is called polyhydramnios and too little is called oligohydramnios. Either can be associated with other problems in pregnancy or birth defects. Performed during the second or third trimester, an AFI ultrasound is often recommended when:

  • The mother has pre-existing conditions, such as high blood pressure or diabetes
  • The pregnancy involves twins or more babies
  • There are problems with the placenta
  • Symptoms of too much fluid are present, such as abdominal discomfort, back pain and extreme swelling in the feet and ankles
  • Symptoms of too little fluid are present, such as leaking fluid
