Ultrasonography
About Ultrasonography
Ultrasonography, also known as an ultrasound scan, is a non-invasive imaging technique that uses high-frequency sound waves to produce real-time images of organs, tissues, and blood flow inside the body.
Purpose & Types of Ultrasonography in a Hospital:
Ultrasonography is widely used across medical departments for diagnosis, monitoring, and guiding procedures.
Purpose of Ultrasonography:
- Pregnancy and Obstetrics
- Monitoring fetal development and heartbeat
- Detecting birth defects, multiple pregnancies, or complications
- Determining gestational age and due date
- Abdominal and Pelvic Imaging
- Evaluates organs like the liver, kidneys, gallbladder, pancreas, spleen, bladder, and uterus
- Detects cysts, tumors, stones, or fluid collections
- Cardiology (Echocardiography)
- Specialized ultrasound of the heart (discussed earlier)
- Musculoskeletal Imaging
- Visualizes muscles, ligaments, and tendons to detect injuries or inflammation
- Blood Flow and Vascular Studies (Doppler Ultrasound)
- Assesses blood flow in arteries and veins
- Detects blockages, clots, or narrowed vessels
- Guiding Medical Procedures
- Assists in:
- Needle biopsies
- Fluid drainage
- Catheter placement
Types of Ultrasonography:
2D Ultrasound: Basic grayscale imaging
3D/4D Ultrasound: Advanced imaging, especially used in obstetrics
Doppler Ultrasound: Measures the speed and direction of blood flow
Transvaginal/Transrectal Ultrasound: Internal probes for detailed imaging of pelvic organs
