Vantage Titan, a wide-bore 1.5T scanner, highlights MR offerings from Toshiba America Medical Systems at the RSNA meeting this week. The work-in-progress features a bore 18% wider than any 1.5T scanner currently on the market, according to the company. A specially designed gradient system offers an amplitude of 30 and a slew rate of 130 to expand the field-of-view.
Radiologists who wonder why diagnostic imaging has been targeted for utilization constraints need only examine the Medicare B experience from 2000 to 2005. Medicare payments for outpatient medical imaging rose 93% during that period from $6 billion to more than $11 billion. The increase reflected a shift in preference to high-cost, high-tech modalities, especially CT and MR. Utilization among cardiologists exploded.
Medison America spotlights the Accuvix V10 this week at the RSNA meeting. The ultrasound scanner, which appeared last year as a work-in-progress, cleared the FDA in spring. It supports 3D/4D imaging, as well as spectral, color, and power Doppler.
An overwhelming majority of the audience at an RSNA special focus session Thursday voted in favor of keeping up the efforts to get FDA approval for the use of contrast ultrasound for general radiology applications.
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.
Professional attendance at the 2007 RSNA meeting saw a 3% increase compared with last year. Society officers credit a large contingent of international attendees for the rising figures.
The lack of an effective, detailed workup algorithm for positive results in multicenter lung cancer screening trials results in a lower cancer yield from invasive procedures and later diagnoses for participants, according to a new study presented at the RSNA meeting.
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.
In what is possibly the largest study in its kind, Harvard University researchers have shown that PET/CT can reliably tell whether unsuspected adrenal lesions discovered while managing oncologic patients are benign or malignant.
Merge Healthcare has become the first U.S. RIS/PACS company to enter the fast-growing teleradiology market, offering a service that gives U.S.-based radiologists consultation interpretations provided by radiologists based in India.
