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.
Interventional oncology (IO) procedures are commonly applied to treat primary or metastatic cancer. IO treatments may be also offered in combination with any of the above oncological therapies in order to augment the therapeutic outcome in more complex or widespread (metastatic) cancer cases.
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.
We all might be aware of ultrasounds from movies or TV shows, but not everybody knows that sonograms can actually be helpful for a lot more things besides pregnancy, whether that be looking at a ...
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 ...
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices.
“The ultrasound or MRI scans you are referencing are covered by Medicare when provided as a diagnostic test,” the spokeswoman said. “If the scans were provided as a screening test, then ...
In uncertain cases complementary dynamic imaging techniques or biopsy should be performed. When Doppler exploration is not enough, CEUS examination will be performed. One should always keep in mind the risk of false positive results for HCC in case of cholangiocarcinomas so complementary diagnostic procedures should be considered. [citation needed]
