CT finds high-risk plaque with nanoparticle contrast
May 11, 2007 -- A new animal study by researchers in the U.S. and France brings intriguing new possibilities to CT with its use of a nanoparticulate contrast agent administered before scanning to detect unstable atherosclerotic plaques. The group aims to someday detect human plaques at the greatest risk of rupture while there is time to prevent it. Read More
MDCT catches stenoses up to 4 mm in large coronary vessels
May 9, 2007 -- Using a 75% threshold, Japanese and U.S. investigators found that 64-slice multidetector-row CT (MDCT) could accurately diagnose coronary artery stenosis, according to a presentation at the 2007 American College of Cardiology (ACC) meeting in New Orleans. Read More
Optimized barium, easier prep improve VC experience
April 18, 2007 -- Some see virtual colonoscopy combined with a gentler bowel prep as an important way to get patients to undergo colon cancer screening. And unlike conventional colonoscopy, VC is in a position to make things easier for the patient. Studies are experimenting with gentler regimens that produce less discomfort and mark the residual stool. Recently, researchers tried to find the optimal formula for reduced-prep VC. Read More
Multivendor digital mammo project makes mark in Germany
April 16, 2007 -- Digital mammography is often deployed in a heterogeneous IT environment with different developers' RIS, PACS, and archive products interacting with the modality, presenting a host of integration concerns. A group of information systems administrators in Germany recently faced the challenge of bringing CR mammography online and discovered that successfully assimilating the modality into the enterprise is not just an issue of interfacing the technology.

Norwegian teleradiology project overcomes technical, political hurdles
April 11, 2007 -- Steering information from disparate RIS and PACS products throughout an enterprise has historically presented a challenge for IT system administrators: it can be done, it just hasn't been easy. One country that has tackled the challenge is Norway. In 2003, the regional health authority of western Norway initiated a teleradiology project to improve the retrieval of radiology exams across the entire region. In the process, both management and technology hurdles were overcome. Read More
GRAPPA MRA curtails gadolinium dose in peripheral arterial occlusive disease
March 21, 2007 -- Using a parallel acquisition technique can reduce the amount of gadolinium needed for intra-arterial MRI, according to Swiss imaging experts. Furthermore, a high contrast-to-noise ratio (CNR) can be achieved in the vessel lumen, they wrote in the American Journal of Roentgenology. Read More
Siemens, BrainLab bring intraoperative CT scanner to the U.S.
March 20, 2007 -- U.S. facilities are about to get their first look at a novel concept in intraoperative CT, thanks to a partnership between image-guided therapy firm BrainLab and Siemens Medical Solutions. The companies have developed an intraoperative CT system that slides into position for use during surgical procedures, eliminating the need to move patients out of the operating suite for additional imaging.

German group presents results with prototype breast CT scanner
March 11, 2007 -- VIENNA - A German research group presented preliminary work on a dedicated breast CT scanner at this week's European Congress of Radiology (ECR). While the group has only studied phantoms with the prototype system, their results so far indicate that the scanner can achieve twice the resolution of conventional mammography at an equivalent radiation dose.

Reconstruction kernel dramatically affects stent evaluation
March 11, 2007 -- VIENNA - If the results of a phantom study are valid in patients, the choice of reconstruction kernel with 64-slice CT has a critical impact on coronary artery stent evaluations. And as Dr. Florian Wolf explained at today's cardiac imaging sessions at the European Congress of Radiology (ECR), the evaluation of stents for detecting restenosis is critical for patient outcomes.

European radiology mobilizes to stave off MRI safety rules
March 9, 2007 -- VIENNA - A number of European academic societies, including the European Society of Radiology (ESR), have formed a coalition to try to prevent the adoption of safety rules set to go into effect in 2008 that could severely limit the types of MRI studies that can be conducted in the European Union. Called the Alliance for MRI, the coalition was launched here today at the European Congress of Radiology (ECR). Read More
