Ultrasound is a valuable tool, but it has limitations. Sound waves don't travel well through air or bone. This means ultrasound isn't effective at imaging body parts that have gas in them or are hidden by bone, such as the lungs or head. Ultrasound also may not be able to see objects that are located very deep in the human body.
High-intensity focused ultrasound (HIFU) Overview High-intensity focused ultrasound (HIFU) uses focused sound waves to heat and destroy a targeted area of tissue while leaving nearby areas unharmed. It's generally done under the guidance of MRI or ultrasound imaging. HIFU involves no incisions, lasers or radiation.
Doppler ultrasound is a noninvasive test that can be used to measure the blood flow through your blood vessels. It works by bouncing high-frequency sound waves off red blood cells that are circulating in the bloodstream. A regular ultrasound uses sound waves to produce images, but can't show blood ...
Fetal ultrasound should only be done for medical reasons as part of prenatal care, based on the advice of a doctor or other licensed health care professional.

The ultrasound wand goes through the catheter and moves near the heart. The wand gives off sound waves. It records the sound waves that bounce back from the heart. A computer changes the information into moving images. The images are seen on a monitor. A healthcare professional watches your oxygen level during the test. Stress echocardiogram
Carotid (kuh-ROT-id) ultrasound is a procedure that uses sound waves to look at blood flow through the carotid arteries. The carotid arteries are a pair of blood vessels on each side of the neck. They deliver blood from the heart to the brain. A carotid ultrasound also checks the thickness of the carotid artery wall and for blood clots.
Overview of ultrasound-guided transperineal prostate biopsies In transperineal biopsy, the urologist passes the biopsy needle through the perineal skin and into the prostate, rather than passing the biopsy needle through a potentially contaminated rectum.
