Accuracy of ultrasound screening in pregnancy

harminka — Wed, 25 Jun 2008 07:02:28 -0500

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

(Nashua, NH) – Imaging agents that can work at the cellular level are positioned to propel noninvasive diagnostics into a new era. These molecular imaging agents can associate with highly specific markers on the surface of cells to provide unparalleled specificity, creating new opportunities for visualization, targeted drug delivery, and mapping physiological changes over time.

High-energy ultrasound sharpens view of liver tumors

harminka — Tue, 08 Jan 2008 07:47:50 -0600

A high-energy form of ultrasound imaging developed by researchers at Duke University's Pratt School of Engineering produces pictures of liver tumors that are better than those made with traditional ultrasound, according to results of a clinical study.

Ultrasound plus mammography finds more cancers

Adding ultrasound to mammography finds more cancers than mammography alone, but also substantially increases the number of false positives, according to first-year results from a three-year study of the two tests.

New acoustic absorber to improve physiotherapy ultrasound machines

Physiotherapy ultrasound machines are commonplace in medicine and sports injury treatment but limitations with current calibration equipment mean they may be producing inaccurate doses that could lead to further injury.

High-intensity ultrasound may launch attack on cancer

harminka — Wed, 08 Aug 2007 04:23:54 -0500

An intense form of ultrasound that shakes a tumor until its cells start to leak can trigger an “alarm” that enlists immune defenses against the cancerous invasion, according to a study led by researchers at Duke University's Pratt School of Engineering.

Mayo Clinic real-time 3-D ultrasound speeds patient recovery

harminka — Sat, 14 Jul 2007 03:59:33 -0500

Mayo Clinic physicians have adapted real-time 3-D ultrasound imaging devices -- including one designed to look at an infant’s heart -- so that they can watch as they use a needle filled with anesthetic to numb individual nerves located inches under the skin.

Improving diagnostic yield in peripheral lung lesions

harminka — Mon, 02 Jul 2007 00:26:27 -0500

The combined use of two minimally invasive techniques—endobronchial ultrasound (EBUS) and electromagnetic navigation bronchoscopy (ENB)-- in the diagnosis of peripheral lung lesions has been shown to be more effective than either procedure alone and does not compromise patients’ safety, according to a new study.
