Imaging Services Q & A

Is there a difference between ultrasound and sonography?

Sonography and ultrasound refer to the same procedure that uses high-frequency sound waves to produce images of organs, tissues, and blood flow. As the sound waves harmlessly enter your body, they bounce off internal structures. The information is transmitted to a computer, which analyzes the sounds to form a detailed image.

How is ultrasound used in obstetrics?

Ultrasound may be best known for its use during pregnancy to evaluate the baby’s progress. Most women are familiar with the second trimester ultrasound, which is routinely performed to check the baby’s heart, measure the baby’s size, and assess development.

Parent’s often learn the baby’s sex during the second trimester ultrasound -- but not always. If the imaging is done too early, the baby’s external genitals may not be developed well enough to be visible. The baby’s position in the womb can also prevent the ultrasound from picking up the image.

How is imaging used for gynecologic care?

Imaging is essential for diagnosing many gynecologic problems. As ultrasound provides detailed views of your cervix, uterus, fallopian tubes, and ovaries, the providers at Fairfax OB-GYN Associates can determine the cause of health conditions such as:

  • Endometriosis
  • Ectopic pregnancy
  • Uterine fibroids or tumors
  • Ovarian cysts
  • Breast lumps

Ultrasound imaging is performed when a suspicious lump is found in a woman’s breast. It provides enough detail to determine whether the lump is a fluid-filled cyst or a solid tumor. It also shows the precise location and size of the lump, so that a biopsy can be performed. While ultrasound distinguishes the type of lump, a biopsy is required to learn whether it’s cancerous.

Are you at risk for osteoporosis?

Women are vulnerable to osteoporosis after menopause, because loss of estrogen causes more calcium to leave the bones. For this reason, women should get screened for osteoporosis after they reach menopause, or at least by the age of 65.

Women may need bone density screening before menopause if they’re at risk for osteoporosis due to:

  • Low calcium consumption
  • Lack of exercise
  • Corticosteroid medications
  • Weight loss surgery
  • Certain medical conditions such as inflammatory bowel disease and overactive thyroid

Bone density examinations are performed at Fairfax OB-GYN Associates using dual-energy x-ray absorptiometry, or DEXA, which uses a small dose of radiation to measure bone loss.
