A technique previously shown to diagnose cardiogenic pulmonary edema has now been used to successfully diagnose pulmonary edema brought on by high altitude. Pulmonary edema is the primary cause of death from altitude sickness, and ultrasound could be an effective, low-cost test suitable for field hospitals.
A method of automatically combining CT, PET, and ultrasound scans into one image may help clinicians diagnose gynecological cancers. Together, the three modalities provide a clearer picture of indeterminate solid masses in the pelvic area.

Concerns about the danger of thrombosis resulting from the use of drug-eluting stents, combined with confidence in the safety of bare metal stents, have driven down the use of drug-eluting stents substantially over the past year, according to Volcano Corporation. That’s bad news for the makers of drug-eluting stents but good news for the makers of intravascular ultrasound systems. The top executive at Volcano reports a surge in the sale of the systems.
Ultrasound strain imaging, or elastography, can show the difference between a benign breast mass and a tumor, avoiding biopsy. Although accuracy depends on the skill of the reader, strain imaging can be used to better determine which masses should be biopsied.

Like many legal feuds between two major competitors, the one now building between SonoSite and Zonare has broad ramifications that threaten to involve other companies and their products. Whether the case spills into the rest of the ultrasound industry may depend on the specifics of two patents now at issue.

The double lung point is an ultrasound sign that may help diagnose transient tachypnea of the newborn, a respiratory disorder currently diagnosed mainly by excluding other disorders. A recent study identified the double lung point in newborns already diagnosed with transient tachypnea.
Physicians, scientists, and other stakeholders formed the Foundation for Focused Ultrasound Research in January 2005 as a nonprofit vehicle to promote the specialty of high-intensity focused ultrasound.
High-intensity focused ultrasound (HIFU) has shown promise as a pain management strategy in patients with bone metastases for whom other treatments are ineffective, according to researchers at the Sheba Medical Center in Israel (Ann Oncol 2007;18:163-167).
The use of high-intensity focused ultrasound for various therapeutic applications has continued to grow since Lynn et al first proposed it in 1942.1 Advances in medical imaging technology in the last two decades have led to its widespread use in both research and clinical practice for the treatment of benign and malignant tumors, hemostasis, uterine fibroids, and other conditions.
For the first time, data accrued over a decade show that the involvement of the pharmaceutical industry in clinical breast cancer research may have significantly influenced study design, focus, and results, according to a study published in the April 1 issue of Cancer.
Women's health and imaging's role in it are of enormous social, economic, and psychological importance. Recognition of this importance prompted the University of Rochester Medical Center's imaging sciences department to hold its first annual Women's Health and Imaging in a Digital Environment conference in San Antonio, TX, in January 2007.
Modern high-resolution ultrasound has excellent spatial and contrast resolution for the near field, and the development of 3D technology, extended field-of-view or panoramic imaging, and color flow and power Doppler applications has led to great improvements in its diagnostic utility and accuracy.

Diagnosis of pneumoperitoneum with ultrasound could be more consistent and reliable if operators look for the enhanced peritoneal stripe sign. A recent study from an emergency room setting in India showed that this method, which proved reliable in animal models, was also an accurate sign of air in the peritoneal cavity in humans.

Trails blazed in medicine often bring controversy and even consternation. Breast care is no different. Since 1965, when the American College of Radiology formed the Committee on Mammography, advances in breast imaging and legislation to ensure its quality have largely centered on x-ray mammography.
Zone Sonography had been on the market for nearly two years before SonoSite formally charged its developer, Zonare Medical Systems, with patent infringement. In its lawsuit, filed in late February, SonoSite alleged that Zonare’s z.one, which converts from a midtier cart-based system to a compact hand-carried unit, violates its “412 patent,” described generally as covering a portable ultrasound system weighing less than 10
In late February,SonoSite -- the first company to commercialize a modern hand-carried ultrasound unit -- filed a lawsuit alleging patent infringement in the U.S. District Court for the Central District of California, Southern Division. This lawsuit, while specific to Zonare Medical Systems, holds extraordinary significance for all developers of hand-carried ultrasound systems, putting the industry on notice that SonoSite will vigorously defend its intellectual property.
Ultrasound is more accurate than conventional screening for detecting goiter in patients on long-term lithium therapy, according to a recent study from Germany. Lithium therapy inhibits normal function of the thyroid, but clinical inspection and palpation missed goiter in some patients in whom it was detected with ultrasound.
