Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
Fracture sonography is the use of medical ultrasound to detect bone fractures. While medical ultrasound is used to visualize soft tissues like skin, organs, and blood vessels, fracture sonography is used to visualize fractures on only bone surfaces. It is useful for children aged 12 or younger because all fractures cause alterations of the bone ...
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.
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]
Ovarian cancer most often occurs after menopause with 50% of these cancers developing after age 63, the American Cancer Society notes. Symptoms of borderline ovarian tumors are the same as “any ...
Ultrasound is also used as a popular research tool for capturing raw data, that can be made available through an ultrasound research interface, for the purpose of tissue characterization and implementation of new image processing techniques. The concepts of ultrasound differ from other medical imaging modalities in the fact that it is operated ...
When concerns arise about other damages due to leukemia, doctors may use an X-ray, MRI, or ultrasound. These can potentially show leukemia's effects on such body parts as bones (X-ray), the brain (MRI), or the kidneys, spleen, and liver (ultrasound). CT scans can be used to check lymph nodes in the chest, though this is uncommon. [63]
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 ...
