Ultrasound technology has two distinct applications in healthcare - diagnostic and therapeutic. While they use similar technology, their purposes are quite different.
Diagnostic Ultrasound
Diagnostic ultrasound is a non-invasive technique used to image organs inside the body using high-frequency sound waves that are above the audible range.
How It Works
A handheld transducer and gel are used to visualise internal structures on a monitor. The sonographer moves the transducer across your skin, and the sound waves create detailed images in real-time.
What It's Used For
Diagnostic ultrasound assists healthcare professionals in:
- Examining internal organs
- Identifying abnormalities
- Monitoring pregnancy
- Guiding diagnosis and treatment planning
Who Performs It
Sonographers (also called ultrasonographers) are the specialists trained to perform diagnostic ultrasound examinations.
Therapeutic Ultrasound
Therapeutic ultrasound uses similar sound wave technology but doesn't generate images. Instead, it functions as a treatment modality.
What It Treats
Therapeutic ultrasound works well for soft tissue injuries such as:
- Tendonitis - inflammation of tendons
- Non-acute joint swelling - ongoing joint issues
- Muscle spasm - tense, painful muscles
- Ligament injuries - sprains and strains
How It Helps
The ultrasound waves promote healing and alleviate pain in muscle and ligament injuries by:
- Increasing blood flow to the area
- Reducing inflammation
- Promoting tissue repair
- Relaxing muscle tension
Who Performs It
Physiotherapists and occupational therapists typically administer therapeutic ultrasound treatments.
