Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g., distances and velocities) or to generate an informative audible sound.
However, it is able to detect the appearance of new lesions and to assess the occurrence of any complications of disease progression (ascites or portal vein thrombosis). Color Doppler ultrasound can be useful sometimes being able to show the presence of intratumoral vasculature as a sign of incomplete therapy or intratumoral recurrence.
Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and ...
The most accurate ultrasound test can detect 96% of ovarian cancers in postmenopausal women, new research suggests. The findings indicate that the test should replace the current standard of care ...
Ultrasound image showing the liver, gallbladder and common bile duct. Medical ultrasound uses high frequency broadband sound waves in the megahertz range that are reflected by tissue to varying degrees to produce (up to 3D) images. This is commonly associated with imaging the fetus in pregnant women. Uses of ultrasound are much broader, however.
Ultrasound can be used for additional anatomical information for patients with an abnormal kidney function or pancreatic enzymes (pancreatic amylase and pancreatic lipase). Standard measurement of the abdominal aorta [4] It can be used on the abdominal aorta to detect or exclude abdominal aortic aneurysm.
Ultrasound has been used to trigger the release of anti-cancer drugs from delivery vectors including liposomes, polymeric microspheres and self-assembled polymeric. [ 15 ] Phonophoresis is a form of soft tissue treatment that involves the use of ultrasound combined with medication gels to enhance drug delivery to the desired area.
Palpation has long been used to detect disease. In a breast self-examination, women look for hard lumps, as cancer is usually stiffer than healthy tissue.. Palpation is the practice of feeling the stiffness of a person's or animal's tissues with the health practitioner's hands.
