Ultrasound has been used a cancer therapy since the 1930s. [4] Initially, high-intensity beams were used to heat and destroy cells. Separately, contrast agents were injected prior to ultrasound, which then destroyed nearby cells. However, heat can harm healthy cells as well as cancer cells, and contrast agents work for only a few tumors.
A meta-analysis found that ultrasound therapy is effective in reducing pain, increasing ROM, and reducing WOMAC functional scores in patients with knee osteoarthritis. [7] There are three potential therapeutic mechanisms of ultrasound in physical therapy. The first is the increase in blood flow in the treated area.
In the field of cancer, ultrasound is commonly used for helping health care professionals detect and develop a diagnosis in affected patients. [34] In the context of drug delivery, ultrasound has been used for a wide variety of therapeutic applications which include but are not limited to melanoma, [16] ovarian cancer, [7] [16] and breast cancer.
Sonodynamic therapy (SDT) is a noninvasive treatment, often used for tumor irradiation, that utilizes a sonosensitizer and the deep penetration of ultrasound to treat lesions of varying depths by reducing target cell number and preventing future tumor growth.
Ultrasound energy is a form of therapy being studied as an anticancer treatment. Intensified ultrasound energy can be directed at cancer cells to heat them and kill them. Recent testing has shown that ultrasound can increase the effectiveness of cancer treatments such as chemotherapy and radiation therapy.
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 ...
The Network expects the new machines to cut waiting times, provide better care and allow new forms of treatment. More: UVM Cancer Center bringing innovative cell-based treatment to Vermont: Who it ...
CEUS examination cannot completely replace the other imaging diagnostic methods currently in use because of the known limitations of the ultrasound method (operator/ equipment dependent, ultrasound examination limitations). In addition to bloating, in cancer patients post-therapy steatosis occurs, which prevent deep visibility.
