Ultrasound / Sonogram (2D, 3D, 4D)
Ultrasounds have many applications in obstetrics and gynecology, including monitoring fetal development and diagnosing diseases and disorders. At Advantia OB-GYN Shady Grove, patients have access to the most advanced ultrasound technology for 2D, 3D and 4D scans.
How are ultrasounds used in gynecology and obstetrics?
Nearly everyone is familiar with the use of ultrasounds during pregnancy to track the growth and development of the baby and to look for issues and abnormalities that could pose a problem during delivery, but ultrasound has many other applications in gynecology as well. Some of the most common uses of ultrasound include:
- Evaluating the structure and function of the uterus, fallopian tubes, and other structures
- Determining the cause of some types of incontinence or incontinence symptoms
- Diagnosing the cause of pelvic pain or abnormal bleeding
- Evaluating fibroids or cysts
- Determining if a tumor is present
Ultrasounds look not only at the structure and anatomy but also at the processes that are taking place, providing both still images and video when needed. Ultrasounds are also referred to as sonograms.
What are the differences between 2D, 3D, and 4D ultrasounds?
The primary differences are the amount of details they produce and the quality of the image. Two-dimensional ultrasounds are the “traditional” type of ultrasound that has been used for many years to diagnose issues and manage treatment. Three-dimensional ultrasounds create a 3D image with greater detail that can be used to diagnose some types of diseases and disorders, and 4D ultrasounds are ultrasounds that allow real-time videos to be captured. In pregnancy, 3D and 4D scans are optional and are typically not covered by insurance. Many parents opt to have them as keepsakes and to gain very clear images of their baby as it develops.
How are 2D, 3D and 4D ultrasounds performed?
The same techniques are used for 2D, 3D, and 4D scans. Ultrasounds begin with the application of a water-based gel to enable the handpiece, or transducer, to make better contact with the skin. During the scan, the transducer is moved across the skin surface, transmitting ultrasound waves through the skin and sending data back to the computer, which uses the data to create images. Transvaginal ultrasounds use a special wand that is inserted into the vagina to obtain images.
