LDR prostate brachytherapy (seed or polymer source implantation) is a very effective treatment for low to high risk localized cancer, with patients rapidly returning to normal activities. [15] Although patients may experience urinary problems for the first six months or so after their implant, these usually settle down and lasting problems are ...
Sonodynamic therapy could be used to treat cancers and other diseases, such as atherosclerosis, and diminish the risk associated with other treatment strategies since it induces cytotoxic effects only when externally stimulated by ultrasound and only at the cancerous region, as opposed to the systemic administration of chemotherapy drugs.
Therapeutic ultrasound refers generally to the use of ultrasound for the treatment of a medical condition or for therapeutic benefit. Physiotherapeutic ultrasound was introduced into clinical practice in the 1950s, with lithotripsy introduced in the 1980s. [ 1 ]
Body sites in which brachytherapy can be used to treat cancer. Brachytherapy is commonly used to treat cancers of the cervix, prostate, breast, and skin. [1]Brachytherapy can also be used in the treatment of tumours of the brain, eye, head and neck region (lip, floor of mouth, tongue, nasopharynx and oropharynx), [10] respiratory tract (trachea and bronchi), digestive tract (oesophagus, gall ...
Studies on localized prostate cancer showed that, after treatment, progression-free survival rates were high for low- and intermediate- risk patients with recurrent prostate cancer. [3] The InsighTec ExAblate 2000 was the first MRgFUS system to obtain FDA market approval, [ 4 ] US patent 5,247,935.
This localized approach aims to increase treatment efficacy and minimize side effects. For instance, ultrasound-based contrast media, such as microbubbles, can accumulate in hypervascularized tissues and release the active ingredient in response to ultrasound waves, thus targeting a specific area chosen by the sonographer.

Tumor characterization using the ultrasound method will be based on the following elements: consistency (solid, liquid, mixed), echogenicity, structure appearance (homogeneous or heterogeneous), delineation from adjacent liver parenchyma (capsular, imprecise), elasticity, posterior acoustic enhancement effect, the relation with neighboring ...
