Ultrasound may help to avoid unnecessary cancer surgery

harminka — Wed, 23 Sep 2009 09:44:02 -0500

Researchers have shown for the first time that patterns of ultrasound signals can be used to identify whether or not cancer has started to spread in melanoma patients, and to what extent. The discovery enables doctors to decide on how much surgery, if any, is required and to predict the patient's probable survival.

In recent years HIFU has been widely used for the treatment of solid tumors, such as liver tumor, bone tumor, and breast cancer. The mechanism for therapeutic actions of HIFU includes thermal effects and non-thermal effects with the latter dominated by cavitational effects.

Ultrasound waves aid in rapid treatment of DVT

In a twist on nontraditional uses of ultrasound, a group of neuroscientists at Arizona State University has developed pulsed ultrasound techniques that can remotely stimulate brain circuit activity.

Accuracy of ultrasound screening in pregnancy

International studies indicate that there is an association between examiner qualifications and device quality on the one hand, and detection rates of ultrasound screening tests in pregnancy on the other. However, it is unclear which minimum preconditions must be fulfilled in order to achieve sufficiently high detection rates for major foetal abnormalities.

Siemens' New Ultrasound Platform Revolutionizes Paradigm of Echocardiography
