Ultrasound

Use of transvaginal sonography increases detection of ectopic pregnancies when patient history and clinical evaluation alone aren’t sufficient for diagnosis.

Emergency ultrasound may accurately diagnose cranial fractures in head-injured children with localized signs of head trauma compared with CT scanning.

Most men with small abdominal aortic aneurysms, 3.0 cm to 5.4 cm, could be safely monitored with ultrasound at longer intervals.

MR elastography is the preferred method for assessing liver stiffness and is growing in availability. Here’s the background, benefits, and future of this nascent modality.

CHICAGO - Point-of-care ultrasound has become ubiquitous in medicine, but radiologists still have a critical role in the modality with ultrasound’s training and promotion.

GE Healthcare axquires U-Systems Inc., developer of the Automated Breast Ultrasound, a system used as a supplement to mammography for asymptomatic women with dense breasts and no prior interventions.

Minimally invasive musculoskeletal ultrasound provides a fast, accurate diagnosis of rheumatic diseases, among other benefits, researchers said.

Breast ultrasound is superior to mammography for initial evaluation in symptomatic women aged 30 to 39 and should be the primary imaging modality.

U-Systems’ somo •v Automated Breast Ultrasound (ABUS) system is approved for use in combination with mammography for women with dense breast tissue.

It is most cost-effective to screen men over the age of 65 for AAA twice than not to screen them at all.

Optical ultrasound tomography holds promise for color imaging brain traumas to breast cancers. The head of one start-up venture explains this new technology.

Cancer screening for patients with alcoholic liver damage may not be cost effective due to their low incidence of hepatocellular carcinoma deaths.

A specific type of ultrasound called speckle-tracking echocardiography may detect heart disease complications from rheumatoid arthritis.

Contrast-enhanced ultrasounds are an effective complementary tool in following up patients who undergo endovascular repair for abdominal aortic aneurysm.

Researchers found ABUS takes three minutes of physician interpretation time compared with 20 to 30 minutes for hand-held ultrasounds.

The Vivid E9 Breakthrough 2012 includes a 4-D transducer for transesophageal echocardiography, as well as workflow tools.

Ultrasound-based transient elastography provides excellent diagnostic accuracy in identifying cirrhosis due to recurrent hepatitis C following liver transplantation.

Siemens Healthcare’s latest release of the ACUSON SC2000 volume imaging ultrasound system has received FDA 510(k) clearance, the company announced.

In this podcast, Tom Gentile, president and CEO at GE Healthcare Systems, explains that “the whole focus of imaging is moving beyond the quality of the image.” Patient care, physician productivity and reimbursement take on a renewed focus in light of healthcare reform efforts internationally, he says.

While the “ultrasound stethoscope” may indeed be moving from science fiction to reality, radiologists remain at the helm for the majority of ultrasound procedures. That’s despite the growth of bedside point-of-care ultrasound, according to a new study published the November issue of the Journal of the American College of Radiology.

Doppler ultrasound can help determine if a baby is allergic to cow’s milk based on the thickness and blood-vessel density in the bowel wall, a team of Brazilian researchers has found.

The reach of portable or compact ultrasound is increasing, with the machines getting smaller, better and more adaptable. In fact, this segment of the market is outpacing the overall ultrasound market.

For a response concerns about nonradiologists using ultrasound technology, we spoke to Christopher L. Moore, MD, assistant professor in the Department of Emergency Medicine at Yale University School of Medicine, who co-authored the New England Journal of Medicine review article behind the initial story.

Imagine a faster, inexpensive method for breast cancer screening. That’s some of the promise behind a new innovation from doctoral student, Sevan Goenezen, who has discovered a way to use ultrasound and advanced algorithms to differentiate between benign and malignant tumors.
