Bedside ultrasound quickly and accurately verifies the placement of endotracheal tubes in pediatric patients, even when the standard tests give false-negative or equivocal results, according to a recent study.

Contrast-enhanced ultrasound of the carotid artery can identify the presence and degree of vascularization in atherosclerotic plaque, providing a noninvasive way to measure the existence and degree of atherosclerosis, according to a recent study.

In an unlikely gathering, representatives of medical imaging and petroleum industries met Nov. 12 at the University of Houston to explore common mechanical problems associated with moving blood and oil through vessels and pipelines.

If we were to believe vendors, radiology would be awash in breakthroughs. But, in reality, industry advances are rare, which is all the more reason to celebrate the events of RSNA 2007.

An overwhelming majority of the audience at an RSNA special focus session voted in favor of keeping up the efforts to get FDA approval for the use of contrast ultrasound for general radiology applications.

Ultrasound-guided percutaneous ethanol injections hold up as a treatment for controlling neck recurrence of papillary thyroid carcinoma. They could be effective for patients who are poor candidates for surgery.

From the first Monday of October to the end of the month, vendor SonoSite commercially launched five hand-carried ultrasound products. It was a month that could change the course of ultrasound.

The palm-sized Acuson P10 ultrasound scanner appears this week as a commercial product from Siemens Medical Solutions along with the laptop-based Acuson P50. The P50 is designed for mobile environments but is outfitted with diagnostic-level capabilities, including high-quality gray-scale as well as color and Doppler imaging. Its primary applications will be in cardiology and vascular imaging.

Toshiba America Medical Systems upgraded its Xario XG and Aplio ultrasound sytems with three transducers, each capable of volumetric scanning. The additions expand the range of these systems, which previously had depended on only one transducer for 4D imaging. The transducers can be applied to transvaginal/obstetric, prostate, small parts including breast, testes, and thyroid, and abdominal scanning.
