Ultrasound fails to spot ovarian cancer

Annual screening with a technique called transvaginal ultrasound, coupled with a blood test for CA125, a protein that can be elevated in the setting of ovarian cancer, does not reliably detect ovarian cancer early, at a more curable stage, according to a new study.

"We and other groups confirm that the current method of ovarian screening, which is a combination of ultrasound scans and (blood) markers, is ineffective," Dr Emma R Woodward from Birmingham Women's Hospital, UK, told Reuters Health.

"Therefore, for women at high risk of developing ovarian cancer, the only real option at present to prevent ovarian cancer death is to have the ovaries removed as a preventive measure."

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.

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.

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.

Chronic Achilles Tendon Pain Eased By Ultrasound-Guided Injections

Patients with chronic tendinosis of the Achilles tendon can experience a reduction in pain when injected with a small amount of a dextrose solution, according to a recent study conducted by researchers at St. Paul's Hospital in Vancouver, BC.

"Chronic tendinosis is a common overuse injury which can be very painful and debilitating and can affect many tendons throughout the body," said Norman J. Maxwell, MD, lead author of the study. "Research has shown that this condition results from impaired healing of recurrent injury to the tendon. Research has also shown that chronic tendinosis is not an inflammatory but a degenerative process," he said.

Small scanners find hidden heart disease


MADISON, Wis. - What if your doctor could swipe a wand over your neck and reveal whether you have hidden heart disease?

That is now possible in places other than the sickbay of the starship Enterprise.

Miniature ultrasound machines are starting to make their way into ordinary doctors' offices, where they may someday be as common as stethoscopes and EKGs. A pocket-sized one weighing less than 2 pounds hit the market last week.

Some of these devices can make images of neck arteries, which offer a "window" to heart arteries that cannot easily be seen. If the neck vessels are clogged, doctors know that those around the heart probably are, too, and that treatment or more testing is needed.

Determining "Vascular Age": Siemens Introduces A New Ultrasound Application For Evaluating The Risk Of Heart Disease

Siemens Medical Solutions expanded its portfolio of ultrasound applications: the syngo Arterial Health Package (AHP) calculates cardiovascular risks by measuring the carotid intima media thickness and determining the so-called vascular age - the relative age of the vessel. Together with other factors, such as cholesterol values and blood pressure, the physician can use the results of syngo AHP to better assess a patient's myocardial or stroke-related risk and establish an individual prevention and treatment plan. At the ESC 2007, the Congress of the European Society of Cardiology in Vienna from September 1 to 5, 2007, Siemens Medical Solutions will introduce syngo AHP for the first time in Europe.

The syngo Arterial Health Package (AHP) determines the vascular age, that is, the advance of atherosclerotic burden and displays it to the patient. Knowing the vascular age supports the physician in more accurately determining the personal risk of a patient to develop coronary heart disease, in rendering a prognosis, and in developing a prevention and therapy plan. The new ultrasound application provides a measurement of the intima media thickness of the carotid - the innermost layer of the carotid vessel wall. An abnormal widening of the intima media is considered evidence of threatening or already existing arteriosclerosis.

High-intensity Ultrasound Helps to Wipe Out Cancer Cells Anywhere in the Body

A new study has found that an intense form of ultrasound that shakes a tumor until its cells start to leak can launch an attack on cancer.

The study led by researchers at Duke University's Pratt School of Engineering has suggested that a high intensity ultrasound can activate an “alarm” that enlists immune defenses against the cancerous invasion.

The new findings from animal experiments imply that once triggered by the ultrasound, the immune system might even search for and devastate cancer cells, including those that have spread through the bloodstream to lurk in other parts of the body.

British sonographers move to stamp out occupational MSK injuries

The Society of Radiographers in the U.K. has published a guidance to help prevent work-related musculoskeletal disorders, the most common work-related illness in Britain.

Studies have repeatedly shown that radiographers and other healthcare professionals who carry out sonography examinations are at particularly high risk of suffering painful conditions affecting the back, shoulders, neck, and arms. These include tendinitis, carpal tunnel syndrome, and tenosynovitis.

"Too many sonographers are being made ill by their work and, in some cases, have to retire because of disabling repetitive strain injuries," said Kim Sunley, the health and safety officer for the Society of Radiographers.

Increasing volumes of work and demanding work schedules within some organizations, exacerbated by staff shortages and the pressures of working in a target-driven environment, may have an impact on the prevalence of musculoskeletal disorders among sonographers, according to the report.

Real-Time 3-D Ultrasound Speeds Patient Recovery

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. In this way, they can quickly block nerve function in selected areas of the body prior to surgery, an advance that may spare patients from use of general anesthesia and sends them home faster and with less need for pain medication.

Mayo anesthesiologists have demonstrated the benefits of real-time 3-D ultrasound in nerve blockade in more than 150 surgeries of varied types. Their presentations at scientific meetings and publications in peer-reviewed journals have informed other physicians worldwide into how this next-era ultrasound imaging technology may assist in peripheral nerve block placement -- the technique of disabling targeted nerves so that a patient doesn't feel pain from surgery.

Ultrasound a Safer Alternative to Invasive Breast Biopsy

A new study has determined that the use of ultrasound for the monitoring of certain breast lesions with a low likelihood of developing cancer may be a safer and more reassuring option than a biopsy.

Chairman of Radiology at Steyr's Ambulatory Care Center in Austria, Dr. Oswald Graf, who was also study author, opined that this method of observing some masses can help women avoid unessential and insidious biopsies.

In a breast ultrasound, images of breast tissues are made with the help of sound waves. This is not as invasive as a biopsy because tissue samples are not collected for analyses as they are with biopsies.

Christian Science Monitor Examines Legislative Efforts To Provide Ultrasounds To Women Seeking Abortions

Ultrasounds have become one of the "latest weapons" in the "battle" between abortion-rights opponents and advocates, the Christian Science Monitor reports. According to the Monitor, six states -- Alabama, Arkansas, Georgia, Idaho, Michigan and Mississippi -- have passed legislation requiring that ultrasounds be offered to women seeking abortions, and four states -- Indiana, Oklahoma, Utah and Wisconsin -- require physicians to notify women seeking abortions about the availability of ultrasounds. According to the Guttmacher Institute, 22 bills relating to ultrasounds were introduced in 15 states this year.

Abortion-rights opponents say ultrasounds are a "medical imperative" for women seeking abortions and they allow women access to all available information before deciding whether to undergo the procedure, according to the Monitor. However, abortion-rights supporters say that ultrasounds are not medically necessary and that laws requiring ultrasounds for women seeking abortions or requiring physicians to offer them are "constitutionally suspect" and a form of "emotional blackmail," the Monitor reports.

SC Senators Drop Mandatory Ultrasound Provision

A South Carolina State Senate subcommittee dropped a provision last Thursday on an abortion bill that would have required women to view an ultrasound image before having an abortion. South Carolina Attorney General Henry McMaster warned lawmakers last week that forcing women to view an ultrasound against her will would be illegal.

While some states have mandated that ultrasound viewing be available, South Carolina would be the only state mandating it if this bill passed with an ultrasound requirement. Democrats anticipate that the bill, which now heads to the Senate Medical Affairs Committee, will easily pass the Senate. A clash is expected, however, because the State Assembly has already approved the bill with the requirement.

New Ultrasound Technique to Detect Breast Cancer

US Researchers have designed a new type of ultrasound which has been tested and found to be very effective in determining whether lumps in breasts are cancerous or not.

The procedure is called elasticity imaging and measures the tissues’ elasticity and compression in response to pressure. Generally tumors are found to be harder and less elastic than benign lumps and thus the test can tell a dangerous growth from a harmless one.

“A tumorous lump should distort very little in response to movement,” said Richard Barr, “whereas a benign one is much more malleable.”

“The finding, if confirmed in a larger trial, could reduce the number of unnecessary breast biopsies and reassure women that their tumors are harmless,” he said . Richard Barr is a radiologist at Southwoods X-Ray and Open MRI in Youngstown, Ohio, who lead the study.

In a special report in this week's British Medical Journal, journalist Geoff Watts considers whether this non-medical use of the technique can be justified

Improvements in ultrasound technology have transformed antenatal scans from two dimensional black and white images to 3D, 4D and even moving pictures of the unborn child। Expectant parents seeking a CD-ROM or a DVD of their scan can expect to pay £150-£250 (€230-380; $300-490).

The companies say that ultrasound has not been shown to cause any harm to mother or baby, but the US Food and Drugs Administration (FDA), the American Institute of Ultrasound in Medicine, and the French Academy of Medicine are among several official bodies that have reservations about such use of the technology.

Ultrasound's future in play: Will radiologists remain in the picture?


Diagnostic ultrasound is ideal for many patients. No other imaging option gives them a real-time look at their own anatomy or so openly encourages discussion with the radiologist about their symptoms and the evidence of disease on the monitor. Ultrasound is safe, patient-friendly, and inexpensive. But while patients welcome it, many radiologists in the U.S. want it to go away.

This contradiction in the application of diagnostic ultrasound was the subject of an October 2006 consensus conference of the Society of Radiologists in Ultrasound (SRU) that brought ultrasound's leadership together in San Francisco. Two days of lectures and debate led to a strategy statement defining a plan to maintain radiology's leadership over the modality (see related article).

U.S. radiologists are not so much turning away from ultrasound, as they are turning toward MRI and CT, said Dr. Harvey Neiman, executive director of the American College of Radiology. Facing an unprecedented demand for their services, they increasingly choose these two modalities because of their superior speed, convenience, and profitability.
