Benefits vs Risks of a Venous Ultrasound
Venous Ultrasound Benefits
- Most ultrasound scanning is noninvasive (no needles or injections) and is usually painless.
- Ultrasound is widely available, easy-to-use and less expensive than other imaging methods.
- Ultrasound imaging uses no ionizing radiation.
- Ultrasound scanning gives a clear picture of soft tissues that do not show up well on x-ray images.
- Ultrasound causes no health problems and may be repeated as often as is necessary.
- Venous ultrasound helps to detect blood clots in the veins of the legs before they become dislodged and pass to the lungs. It also can show the movement of blood within blood vessels.
- Compared to venography, which requires injecting contrast material into a vein, venous ultrasound is more accurate for detecting blood clots in the veins of the thigh up to the knee. In the calf, ultrasound is less accurate.
Venous Ultrasound Risks
- For standard diagnostic ultrasound there are no known harmful effects on humans.
