Ultrasound may Better Classify Ovarian Tumors

Experts examining patterns in ultrasound images can more accurately classify ovarian tumors as benign or malignant than can pre-surgical blood tests, according to a study published online in the Nov. 13 Journal of the National Cancer Institute.

An elevated level of the protein CA-125 in blood is considered an indicator of whether an ovarian tumor is benign or malignant. This measure, however, can often be inaccurate.

Another option is an ultrasound examination of the tumor. An experienced ultrasound examiner can often accurately classify an ovarian tumor using a method of pattern recognition.

Advanced Elastography Features Available on HI VISION(TM) 900 Premium Ultrasound System

Hitachi Medical Systems America anticipates a surge of excitement within the ultrasound community, when more than ten live sessions and written posters evaluating the emerging technique of ultrasound elastography are presented at this year's Scientific Meeting of the Radiological Society of North America.

Elastography is rooted in the practice of palpation, one of the oldest concepts in medicine. When an abnormal mass is discovered in a patient, an important aspect of the initial clinical examination is physically palpating the mass to assess its stiffness. Hitachi's Elastography takes this concept one step further by using ultrasound to perform sophisticated and sensitive measurements of relative stiffness and creating detailed images depicting this information.

Through-Wave Ultrasound: Effective, Economical and Ideal for Breast Imaging, Biopsy

RICHLAND, Wash., Nov. 20 /PRNewswire/ -- Advanced Imaging Technologies,
today announced the ARIA Breast Imaging System (BIS),a real-time through-wave ultrasound imaging system that uses the diffractiveproperties of sound combined with holography (HU) to create highly-detailed,three-dimensional images of breast tissue, is now equipped for image-guidedbiopsy. The automated system has clinically proven to provide superior viewsof the breast tissue, especially dense tissue, while delivering better datafor enhanced diagnostic decision-making. The system's image-guidance for
biopsy will be demonstrated in booth #2179 at the Radiological Society of North America (RSNA) Scientific Sessions November 25-29, 2007 in Chicago.

Siemens Introduces The World's Smallest Ultrasound Unit For Emergency Diagnostics

The first few minutes are often the deciding factor in emergency situations. For this reason, Siemens is now offering a mini ultrasound unit that will enable patients to receive medical treatment faster than ever before. Because this unit is just as compact as a PDA cell phone, weighs only about 700 grams, and easily fits into the physician's pocket. It is thus especially suitable for emergency medical applications, i.e. examining injuries on site in order to ensure that each patient receives the medical treatment he requires.

The "Acuson P10" mini ultrasound unit offers decisive advantages for first aid in outpatient areas, rescue helicopters and intensive care units: It is mobile, easy to operate and available to physicians whenever and wherever it is needed. When set to high-definition ultrasound image acquisition, it can, for example, be used to detect accumulations of liquids in the body and heart action, display any damage to arteries and examine the pelvis. In obstetrics, this mini ultrasound unit can be used even during childbirth to determine the unborn child's location, chances of survival and position, as well as to visualize the amount of amniotic fluid or bleeding and their tendency to escape in due time.

MEDISON Launches New Ultrasound System: ACCUVIX V10

The advanced ultrasound system ACCUVIX XQ has been widely recognised worldwide for its advanced technology and stability, but a new unit is about to steal its thunder.

Produced by South Korea-based MEDISON Co Ltd (CEO: J. B. Choi) ACCUVIX XQ was ranked, according to the Klein Report, in second place in the number of units sold in 2005 as well as 2006 in the US$200 million American obstetrics and gynaecology ultrasound market. However, the XQ has now been superseded by the latest in the line: the ACCUVIX V10.

Screening for Abdominal Aortic Aneurysms in Women May Save Lives

Newswise — In 9 out of 10 cases, a burst abdominal aortic artery is quickly fatal for its most common victim: elderly males. A new study -- the largest yet performed -- now confirms that women over 65 with a history of smoking or heart disease are also at high risk for an abdominal aortic aneurysm (AAA) -- supporting the notion that they should also receive ultrasound screening to help spot and correct the dangerous condition.

The findings, reported in the Journal of Vascular Surgery, challenge current recommendations on AAA screening issued by the United States Preventive Services Task Force. Those guidelines recommend that screening only be performed -- and reimbursed by Medicare -- for men aged 65 to 75 who have ever smoked.

GE Breakthroughs Seek To Re-Invent Cardiovascular Ultrasound

Ultra Definition: True 4D Echo
The Vivid 7 Dimension '08

One has been given the gift of enhanced, crystal-clear sight. The other gets a three-connector docking cart, stress echo and an ergonomic work over. GE Healthcare, the global ultrasound leader, launched two breakthroughs for its popular Vivid e and Vivid 7 Dimension cardiovascular ultrasound systems at this year's meeting of the American Heart Association in Orlando, FL. Building upon GE's successful introduction of Vivid products in 2000, GE continues to bring to market innovative, high-performance cardiovascular ultrasound systems.
