[Therapeutic ultrasound in tumor therapy. Principles, applications and new developments]

Abstract:
We are interested in the interaction of high-energy ultrasound with biological tissue with regard to cancer therapy. The physical and biological aspects of this are reviewed and summarized in this paper. The preliminary results give reason to hope, as ultrasound is easy to focus [correction of focuse] and might be applicable as a supplementary therapeutic technique in ultrasound-accessible tumors. The changes observed in biological studies are clearly a function of the physical parameters. Therefore, it is possible to calculate and predict the biological effects. Recent results have shown the potential of magnetic resonance imaging in monitoring ultrasound therapy online. The capability of MRI to measure temperature will be an important tool for the safe and reliable application of this new therapeutic approach. The role of ultrasound therapy in the management of human tumors must be clarified in carefully conducted clinical trials.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

01:20Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
