While women choose radiology for intellectual stimulation and job satisfaction, they consistently have to overcome the stereotype of the nurturing caregiver, according to survey results presented Monday.

Siemens demonstrated hands-off imaging at the RSNA with a work in progress that turns control of an MR scanner over to remote operators. The goal behind Expert-I, which is pending FDA clearance, is to allow expert collaboration on challenging examinations regardless of how far away the expert may be.

Digital mammography images acquired in a 64-foot van serving Washington residents are as good as mobile film-based images, according to a study from a Seattle breast center.

For radiology to move into the digital arena in underserved areas around the world, financial, cultural, and technological stumbling blocks have to be removed, according to a case study presented Tuesday at the RSNA meeting.

Academic radiologists usually cut to the chase in describing how imaging increasingly factors into drug discovery and research. They display cellular metabolism FDG-PET images or dynamic-contrast MR images quantifying changes in tumor vascularity. These glamor children of radiological research reflect the potential of medical imaging in measuring therapeutic response.

Budget-strapped healthcare providers can bootstrap their way into digital imaging with a new low-cost CR system from Radlink.

Hyperpolarized helium-3 diffusion MR can detect alveolar changes due to lung disease in children and provide quantitative data on airflow to the peripheral lobes, according to research presented Tuesday.

Trainee radiologists can benefit by studying the mistakes of their predecessors and focusing on clinical situations and radiographic findings that are often misdiagnosed.

Digital breast tomosynthesis (DBT) promises to dramatically reduce the rate of false-positive mammograms, potentially sparing women from unnecessary follow-up tests and biopsies, according to a study presented Tuesday.

GE Healthcare launched a new digital radiography line at the RSNA meeting Monday. The first two members of the Definium line are a portable and a fixed digital radiography system.

The computer-aided detection firm R2 Technology has teamed with Swedish workstation leader Sectra to produce a “CAD-intelligent” system that optimizes the presentation of CAD information on mammographic images. The companies jointly launched the Citra mammography applications suite at the RSNA meeting.

GE Healthcare joined the ranks of believers in mega-slice PET/CT with the formal release of its Discovery VCT on the RSNA exhibit floor. The 64-slice hybrid, shown as a work in progress at the 2004 meeting, will compete with the Siemens biograph 64 and Philips Gemini GXL, both 64-slice PET/CT scanners launched one year ago.

Philips and Schering are collaborating in breast imaging, using a fluorescent dye developed by Schering and an experimental optical scanner under construction by Philips. The two technologies will be merged as part of a phase I clinical trial that could begin some time next year.

Once again, I spent much of the day in a case-based review course, this one on interventional radiology. In my practice, we have one real interventional radiologist and two pseudo-interventionalists. The prime difference being that a real interventional radiologist knows what he’s doing. The other big difference is an IR enjoys what he is doing.

CT screening of head and neck vascular injuries by emergency departments could lead to more aggressive therapies that result in improved outcomes, according to a pair of papers presented Monday.

Toshiba is introducing the latest improvements to its Aplio and Xario ultrasound systems at the 2005 RSNA meeting. The Aplio system has been enhanced with the company’s exclusive expanded Differential Tissue Harmonic Imaging (DTHI), while the Xario features 4D imaging.

Many radiology departments aren’t waiting for commercial information systems to address pressing needs like automatic work list prioritization. They are developing their own tools for tackling this common problem, according to presentations at a Monday scientific session.

Continuing medical education is a must for radiologists planning to perform CT colonography, according to two studies presented by U.K. researchers at the RSNA meeting on Sunday.

Computed radiography’s new needle-like phosphor imaging plate technology provides comparable diagnostic performance with only half the radiation exposure required by its predecessor, according to a study presented Sunday. Findings suggest the gap between CR and digital radiography is shrinking as well.

High-field 3D MR angiography can put up a good fight against conventional x-ray digital subtraction angiography for the diagnosis of brain aneurysms and other intracranial vascular malformations, according to studies presented at the RSNA meeting Monday. Three-D MRA also provides reliable follow-up after treatment.
