Ultrasound (2D/3D/4D)

Ultrasound imaging—also known as sonography—is a diagnostic test that uses high-frequency sound waves to create live images of internal body structures. It is a radiation-free, painless, and non-invasive procedure, suitable for patients of all ages, including pregnant women.

There are different types of ultrasound based on the dimensional imaging:

🔹

Types of Ultrasound:

1. 2D Ultrasound (Standard):
   Produces flat, black-and-white images.
   Commonly used for routine diagnostics and fetal scans.

2. 3D Ultrasound:
   Creates three-dimensional still images.
   Offers clearer views of fetal structures or internal organs.

3. 4D Ultrasound:
   Adds the dimension of time to 3D images, showing live motion.
   Often used in prenatal imaging to watch the baby move in real time.

🔹

Common Applications:

• Pregnancy monitoring and fetal development

• Abdominal organ evaluation (liver, gallbladder, kidneys)

• Pelvic imaging (uterus, ovaries, prostate)

• Heart (Echocardiography)

• Thyroid, breast, and scrotal imaging

• Blood flow studies (Doppler ultrasound)

• Guidance for biopsies and fluid drainages

🔹

Procedure:

• A special gel is applied to the skin to help transmit sound waves.

• A handheld device called a transducer is moved over the skin.

• Real-time images appear on a monitor and can be saved for review.

• The test usually takes 15–30 minutes, is painless, and requires no recovery time.

🔹

Benefits:

• No radiation exposure

• Safe for pregnant women and children

• Real-time visualization of organs and blood flow

• Useful for early diagnosis and treatment planning

Ultrasound (2D/3D/4D) is a versatile and essential imaging tool in modern medicine, widely used for diagnostics, monitoring, and minimally invasive procedures—providing safe and immediate insights into the body’s internal conditions.
