This may sound like science fiction, but computed tomography with reduced radiation exposure and the highest soft tissue contrast is likely to be a reality -- very soon. Named phase-contrast imaging, the method is an invention of Professor Franz Pfeiffer, Chair of Biomedical Physics at Munich Technical University, Germany. We asked him to explain the implications this development has for…
For the paediatric radiologist an ultrasound system is as essential as a wrench for the mechanic, for three reasons, says Professor Michel Claudon, Head of the Department of Radiology at the Children's Hospital of Brabois, University of Nancy, France: ‘High image quality due to the low weight of children, which allows medium frequency, the absence of radiation and the possibility of performing…
World of Ultrasound met Prof. Ioan Sporea, Prof. Gebhard Mathis and Prof. Byung Ihn Choi to ask them three questions.
Contrast agents have opened up entirely new possibilities are taking shape for ultrasound, above all in oncology. Following the publication of guidelines on the clinical use of contrast-enhanced ultrasound (CEUS) by the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) in 2004 and 2008, at this year’s World Ultrasound Congress, WFUMB and EFSUMB will present joint…
Although many new features in US-guided interventions are being marketed, which are really necessary, which just nice-to-have? It’s a question to be faced by experts during the refresher course ‘Interventional ultrasound’ at WFUMB 2011. One of the most established ultrasound techniques in minimally invasive procedures is contrast enhanced ultrasound (CEUS) – a tool that is safe, gentle…
Around 700 international experts met in Vienna to discuss the latest advancements in ultrasound, such as a new technique called real time imaging, and of approximately 200 scientific papers. That was back in 1969 when for the first time physicians and scientists from around the world came together in Austria’s capital to share their knowledge of the use of ultrasound waves in medicine. The…
Contrast induced nephropathy (CIN) is widely recognised as a potentially serious complication of contrast media use -- a risk that increases with a patient’s age and decreased renal function. Mark Nicholls reports
Michael Maher, Professor of Radiology at the University Collage, Cork, Ireland, produced an answer to during a GE Healthcare Lunch Symposium at the European Congress of Radiology this March. It is 1.2 millisievert – at least for abdominal CT scans of Crohn’s disease patients.
Medical imaging has recently advanced so rapidly that it should halt. Applying more power to computed tomography (CT) and magnetic resonance imaging (MRI) scanners is becoming too dangerous for patients and healthcare workers. Magnets for the next-generation MRIs are so powerful that they must be moved to a separate building on hospital campuses, while CT radiation levels have risen to alarming…
Bayer HealthCare announced that the company will present preclinical data that introduce investigational compounds for both therapy and imaging in its early oncology pipeline with unique and novel mechanisms at the American Association for Cancer Research (AACR) 102nd Annual Meeting, April 2-6, 2011, in Orlando, FL.
Prostate cancer is the 2nd leading cause of cancer death in men. It is also the most common diagnosed malignancy in men with near 190.000 new cases in the USA in 2008. Despite the larger use of biological tests (such as prostate specific antigen (PSA)) and imaging modalities (trans-rectal ultrasonography (TRUS) and Magnetic Resonance Imaging (MRI)), there is a slight increase in the annual death…
A multi-centre French study is demonstrating that a four-minute ultrasound scan using a contrast agent can be performed after the first month of treatment and provide quantitative proof of whether a tumour is responding to the therapy.
Muscular diseases belong to a heterogeneous group with various causes like neurogenic, metabolic, dystrophic, or inflammatory mechanisms as well as channelopathies leading to disorders of the muscle cell membrane potential. In most progressive disease cases the result is a focal or general muscle weakness that, unfortunately, is a very unspecific symptom. Standard neuromuscular literature…
The 90-minute refresher course ‘Contrast Agent Issues 2010: What the Experts Really Do for Allergies, Contrast-induced Nephropathy, Nephrogenic Systemic Fibrosis, and Extravasation’, to be held during this year’s Radiological Society of North America meeting, will focus on the use of iodinated and gadolinium-based contrast media and the issues, advantages and considerations for patient…
Standard mammography is the most relevant diagnostic tool to address breast cancer: It shows excellent image quality, a smooth workflow, high connectivity and a very good clinical outcome in terms of sensitivity and specificity. However, there are certain shortcomings to it, especially in dense breast tissue.
The overall success of MRI in diagnosing breast cancer and the exploding demand for breast MRI, in particular, have caused a scanner shortage in much of Europe. Dr Jean-Pierre Pruvo, Chairman of the French Society of Radiology, recently raised the alarm: ‘We have hundreds of thousands of women in France at risk for breast cancer, yet we do not have the means to provide a breast examination by…
The limitations of mammography are well documented, yet it is still the gold standard in breast cancer detection - particularly due to the positive cost-benefit ratio. Due to prohibitive costs, MRI exams are performed only in well-defined cases. The HIGHREX project (www.highrex.eu) aims to evaluate Single Shot Spectral Imaging (SSSI) technology for use in mamma diagnostics.
First introduced at ECR 2010, Agfa HealthCare’s DX-M is a CR solution able to handle both needle-based detector plates (NIP), as well as standard phosphor plates (PIP). The solution’s ability to read NIP for Mammography requirements as well as NIP for general radiography means that the solution meets a market demand for high quality diagnostic images across needs, and offers potential dose…
At this year’s ECR, new developments will be outlined during the Contrast agents: Experimental and Clinical session. Mark Nicholls spoke with the session moderator Professor Peter Aspelin, Professor in Diagnostic Radiology at the Karolinska Institute, Stockholm, about their potential.
Professor Roger Tsien, Nobel Laureate in Chemistry 2008 for the ‘Discovery and Development of Green Fluorescent Proteins’, was one three* Keynote Speakers at the opening ceremony of the Medical Physics and Bioengineering World Congress 2009, held in Munich this September.
Especially in times of increasing cost pressure and sinking earnings at constantly increasing quality demands, it is essential to exchange successful internationalisation strategies with international experts. During the MCC hospital world 2009 you can think outside the box and learn from the experiences of your colleagues. Even this year, there will be more than 20 renowned international…
In a symposium organised by Bayer Schering Pharma at the 2009 European Congress of Radiology (ECR), the audience heard a series of four presentations on the potential advantages of high-signal-intensity contrast agents for MRI, focusing on gadobutrol (Gadovist). During the discussion, several claims made by the speakers were challenged and debated by ECR delegates.
With 16 years’ experience in developing contrast media power injectors, Medtron AG recently launched the Accutron HP-D, which, the firm reports, is the only totally wireless, high pressure double-head injector dedicated to all vascular diagnostic and interventional procedures.
Although its standard description is simple: Photo detection at low light levels where single photon absorption events are counted, according to an internationally renowned medical imaging scientist, in terms of X-ray imaging, counting photons may really be the way to see the light.
