Radiologists reassert role in assessing blunt trauma
This year the European Society of Radiology formally recognized Emergency Radiology (ESR) as a sub-specialty putting its full support behind this critical practice area with a scientific subcommittee to encourage specialized research.
Strategies for radiation dose reduction in contrast enhanced CT
Recent years have seen growing awareness among radiologists about the radiation burden delivered by computed tomography. And the amount of exposure is continuing to grow, despite the ability of modern CT scanners to provide good image quality at lower dose.
Agfa unveils new table-top CR
New CR 10-X is a cost-effective entry into computed radiography, without compromising on image quality. Robust yet easy-to-install and maintain solution, offering streamlined and integrated workflow.
MRI will improve the treatment of wake-up strokes
Neurointensivists need to act quickly and carefully – as well as consider later complications or the psychological impact on stroke victims. This potentially debilitating disease was a central discussion among 1,400 participants from 10 countries during the three-day 29th Annual Conference of Neurointensive Medicine (ANIM), an event hosted in January by The German Society for Neuro-Intensive…
What´s new in breast MRI, tomosynthesis and elastography?
MRI: Although an area of constant debate, this is becoming a widely accepted clinical modality in Europe. However, researchers in The Netherlands have shown that performing pre-operative breast MRI in all women with invasive lobular carcinoma (ILC) can reduce the need for re-excision.
Traumatic brain injury: The silent epidemic
Traumatic brain injury (TBI) is one of the world’s biggest public health problems. In the USA, for example, about 1.7 million people sustain TBI every year, costing healthcare $76.5 billion. Yet, the public knows little of the significance of TBI and also it once received the nickname ‘silent epidemic’ by the American Centres for Disease Control and Prevention (CDC).
Classifying COPD
Many smokers continue to use tobacco despite high taxes and drastic health warnings. Indeed, in industrialised countries, tobacco-related mortality rates or illnesses are increasing. These include chronic obstructive pulmonary disease (COPD), the fourth leading cause of death in adults – and rising.
What´s new in neuroradiology and interventional radiology?
When scanning seizures, Dr Walter Kucharczyk, director of MRI at Toronto General Hospital, believes that MRI still remains the best imaging test to discover if there is an anatomic or structural abnormality that might account for a seizure.
Drug smugglers in the gantry
Security checks – the necessary evil for air and land travellers. While luggage scans and body pat-downs are ubiquitous, drug smugglers have increasingly used their own bodies as a vessel to conceal and transport their goods.
The end of blooming effects
During the RSNA 2011, Professor Uwe J Schoepf MD, was asked what will be the chosen procedure of the future in cardiac imaging, he answered without hesitation: ‘Definitely CT,’ and, the Director of Cardiovascular Imaging at the Medical University Charleston, South Carolina.
Successful PACS integration in Mauritius
Cardiovascular surgeon Dr Miodrag Todorovic explains how an island hospital – which is a medical centre of excellence and regional reference centre – is further improving medical care for patients there and in six neighbouring states with the help of a new picture archiving system from Visus
Iterative reconstruction
About two years ago iterative image reconstruction was officially introduced for CT imaging. Since then, no other technological innovation has raised more hope that the dose of X-ray based, cross sectional imaging can be significantly lowered. The possibilities of this procedure have not yet been exhausted.
Phase-contrast imaging will revolutionise X-rays
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…
Emergency radiology
The injury was as spectacular as it was ruesome. Struck by a train a male patient was brought to the emergency department in Munich, his right foot hanging on only by muscle and bloody tendons, the bone shattered.
New technique successfully dissolves blood clots in the brain and lowers risk of brain damage after stroke
Johns Hopkins neurologists report success with a new means of getting rid of potentially lethal blood clots in the brain safely without cutting through easily damaged brain tissue or removing large pieces of skull. The minimally invasive treatment, they report, increased the number of patients with intracerebral hemorrhage (ICH) who could function independently by 10 to 15 percent six months…
Enter the business class in CT
The innovation leader in CT and a pioneer in low dose: Siemens introduced a new class of CT which is built for business and designed for efficiency.
Regulators Work With Medical Industry on Radiation Protection
Putting patient safety first is a priority for both HERCA, the association of the Heads of European Radiological Protection Competent Authorities and COCIR, the European trade association representing the medical imaging, electromedical and healthcare IT industry, who are working together to address concerns related to radiation exposure in computed tomography (CT).
Leipzig´s futuristic operating theatre
The next generation of integrated operating systems celebrated a world premiere in clinical use this November in Leipzig Germany. EH Correspondent Holger Zorn was there when Professor Gero Strauss entered the Surgical Deck of the International Reference and Development Centre for Surgical Technology (IRDC) as ´Commander`.
A conceptual shift for medical device manufacturers
Much has changed for medical device manufacturers. Take scanner development; whereas the aim has long been to increase multi-slices, produce higher field strengths and sharper images, optimise the ergonomics and then launch the new product at a specific group of customers, in recent years this approach became insufficient.
The ascent of image-guided surgical interventions
Medical imaging is no longer limited to diagnosis and evaluation. New, high resolution imaging systems enable very precise positioning of lasers, endoscopes and micro-instruments for surgery near the nerves, spinal cord or blood vessels and for selective tumour destruction, with minimum levels of pain and low complication rates.
The BRANSIST alexa
The multipurpose BRANSIST alexa, which aims to provide total support for advanced catheterisation procedures, features a 12 x 12-inch flat panel detector (FPD) – an ideal size, the manufacturer Shimadzu points out, for covering interventions from head-to-toe, from brain blood vessels, cardiac and abdomen to peripheral blood vessels in the upper and lower extremities.
Quantum leap
Moving from 6-slice scan to a 64 row CT, Vierzon Hospital steps up to advance functionalities and explores the potential for news types of examinations, John Brosky reports.
Researchers Use CT to Recreate Stradivarius Violin
Using computed tomography (CT) imaging and advanced manufacturing techniques, a team of experts has created a reproduction of a 1704 Stradivarius violin. Three-dimensional images of the valuable violin and details on how the replica was made were presented today at the annual meeting of the Radiological Society of North America (RSNA).
Integrated 3-D Imaging Facilitates Human Face Transplantation
By combining conventional medical imaging with some of the same 3-D modeling techniques used in Hollywood blockbusters, researchers are offering new hope to victims of serious facial injuries. Results of a new study on human face transplantation, led by Darren M. Smith, M.D., plastic surgery resident at the University of Pittsburgh Medical Center (UPMC), were presented today at the annual meeting…
