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.
Ultrasound can ablate tumors or other tissue non-invasively. 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.
High-intensity focused ultrasound (HIFU), or MR-guided Focused Ultrasound Surgery is an incision-less therapeutic technique [1] that uses non-ionizing ultrasonic waves to heat or ablate tissue. HIFU can be used to increase the flow of blood or lymph or to destroy tissue, such as tumors, via thermal and mechanical mechanisms.
The work builds on Doll's previous study, published in 2021 in JAMA Oncology. For that work, the team used a simulated cohort of 370,000 Black and white patients. They found the current 4 mm ...
Advances in breast cancer care bring hope. Advances in breast cancer diagnostics and treatment are on the rise, said Baron. Contrast-enhanced mammography can detect small cancers in the breast ...
An ultrasonic examination. Ultrasound is sound with frequencies greater than 20 kilohertz. [1] This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound. Ultrasonic devices operate with frequencies from 20 kHz up to ...
ICD-9-CM. 88.74. OPS-301 code. 3-058. Transrectal ultrasonography, or TRUS in short, is a method of creating an image of organs in the pelvis, most commonly used to perform an ultrasound-guided needle biopsy evaluation of the prostate gland in men with elevated prostate-specific antigen or prostatic nodules on digital rectal exam.
