Doppler Ultrasound

 Ultrasound Examinations That Do Not Require Preparation

The following ultrasound studies typically require no special preparation:

• Axillary Ultrasound – Evaluates lymph nodes, often alongside breast imaging

• Arterial Doppler (Upper/Lower Limbs) – Assesses reduced or blocked blood flow

• Breast Ultrasound – Further evaluates areas of concern seen on mammography

• Carotid Doppler – Examines blood flow in carotid arteries for narrowing or blockage

• Non-Vascular Extremity Ultrasound – Detects soft tissue masses or lesions

• Renal Ultrasound – Assesses kidneys for stones, cysts, or obstruction

• Scrotal Ultrasound – Evaluates testicular pain, inflammation, or vascular issues

• Soft Tissue Ultrasound – Detects infections, inflammation, or masses

• Thyroid Ultrasound – Examines thyroid enlargement or nodules

• Transvaginal Ultrasound – Evaluates pelvic organs for gynecological concerns

• Venous Doppler (Upper/Lower Limbs) – Detects blood clots such as DVT

Ultrasound Examinations That Require Preparation

Proper preparation is essential for accurate imaging. If preparation guidelines are not followed, the examination may need to be rescheduled.

• Abdominal & Right Upper Quadrant Ultrasound – Evaluates organs such as liver, gallbladder, pancreas, and spleen

• Abdominal Aorta Ultrasound – Screens for abdominal aortic aneurysm (AAA)

• Bladder Ultrasound – Assesses bladder volume, stones, and wall thickness

• Obstetric (OB) Ultrasound – Monitors fetal development during pregnancy

• Pelvic Ultrasound – Investigates pelvic pain, bleeding, or reproductive issues

• Prostate Ultrasound – Evaluates prostate enlargement, inflammation, or cancer

• Renal Artery Doppler – Assesses blood flow to the kidneys

Clinical Uses of Ultrasound

Ultrasound is commonly used to:

• Monitor fetal growth and detect abnormalities during pregnancy

• Diagnose conditions affecting the liver, gallbladder, pancreas, thyroid, kidneys, bladder, ovaries, testes, and breast

• Evaluate blood flow in arteries and veins

• Assist in ultrasound-guided procedures such as biopsies and fluid aspirations

Ultrasound During Pregnancy

• Dating Scan (8–14 weeks): Determines gestational age and expected delivery date (EDD)

• Anomaly Scan (18–21 weeks): Detects fetal structural abnormalities

• 4D Ultrasound: Provides real-time images of the fetus, often performed around the sixth month, allowing parents to see facial features and movements

Role of Ultrasound in Women’s Health

Ultrasound is a safe and primary diagnostic tool for evaluating various gynecological conditions, including:

• Polycystic Ovary Syndrome (PCOS)

• Fibroid uterus

• Endometriosis

• Ovarian cysts

• Gynecological cancers of the uterus and ovaries
