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.
As the use of interventional procedures to diagnose and treat diseases increase worldwide, and the procedures grow in complexity and length, exposure to radiation is a growing concern for both clinicians and patients. GE’s Innova imaging systems help clinicians reduce radiation exposure without compromising the image quality they need to help them make confident decisions during interventional…
ContextVision, the software imaging partner for the most recognized medical imaging manufacturers worldwide, today introduced two innovative solutions at the 2011 European Congress of Radiology (ECR). A mammography solution addresses current limitations of x-ray image diagnosis for the detection of breast cancer, while the interventional radiology solution helps achieve superior, real-time images…
Toshiba Medical Systems introduced the Aquilion Prime CT scanner, the latest member of the CT family Volume CT Aquilion ONE. Equipped with cutting edge technology for dose reduction and a gantry bore of 78cm, the innovative 160 multislice CT Aquilion Prime defines the next generation of CT scanners.
SECure TRAnsmission, the main aim of a spin-off from the Linköping Institute of Technology, was established in 1978. From this beginning, the Swedish firm Sectra has evolved into one of the world’s leading players in PACS and mammography solutions. Although secure communication systems remains a core business, the medical section has constantly grown since 1988, when Dr Torbjörn Kronander…
Siemens has incorporated three further healthcare products into its environmental portfolio: The Somatom Definition Flash computer tomograph, the Axiom Luminos dRF fluoroscopy system and the Ysio X-ray system have successfully completed both internal evaluation and an external audit. Backing up their clinical performance and energy efficiency, the devices present a convincing case thanks to their…
The risk of developing radiation-induced cancer from computed tomography (CT) may be lower than previously thought, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).
Increasing access. Improving quality and efficiency. Lowering costs. When GE launched its healthymagination initiative last year, these were the long-term goals and at RSNA 2010, GE Healthcare highlighted a variety of technologies developed to support this strategy and help improve patient care worldwide.
During RSNA, Philips announced the new Philips Ingenuity CT platform, an innovative technology that will help redefine low dose imaging. The Ingenuity CT features iDose4, Philips’ next-generation iterative reconstruction technique, designed to provide equivalent diagnostic image quality at up to 80 percent less dose; improve spatial resolution by up to 35 percent with up to 50 percent less…
Ultrasound is the undisputed choice for foetal imaging. However, the lack of amniotic fluid, an unfavourable foetal position or maternal obesity could daunt even the best radiographer. In such circumstances prenatal magnetic resonance imaging (MRI) – a non-invasive and non-irradiating procedure – is a helpful diagnostic tool.
To make today’s cardiac CT examinations even safer, Toshiba introduces new, revolutionary “Adaptive Iterative Dose Reduction (AIDR)” technology that lowers the radiation dose to the patient by up to 75% compared to conventional scanners.
Recent reports on cancer risk from radiation at CT have sparked new concern and discussion in the medical community as well as in the general public. It has been suggested that CT may be responsible for up to 2% of all cancers.
The lungs had to be regarded as the black hole for MRI for a long time. However, since the introduction of substantial improvements in hardware and scanner technology, there is certainly light at the end of the tunnel. MRI offers two main advantages for the diagnostic pathways for pulmonary diseases applied today.
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…
January saw the release of a German language version of Radiation Passport, an iPhone application that enables patients to calculate estimated radiation exposure from diagnostic imaging procedures and keep a personal record of their examinations. Radiation Passport costs US$3.99; by the end of 2009 over 1,000 English language versions were sold.
An international study, conducted by the International Atomic Energy Agency (IAEA), has shown that some countries are over-exposing children to radiation when performing computed tomography (CT) scans. These children are receiving adult-sized radiation doses, although experts have warned against the practice for over a decade.
The threat of litigation is becoming an increasing area of concern in radiology circles. The changing role of the radiologist with a growing workload and more information now available in imaging examinations, have combined with an expectation of greater accuracy from patients to raise the threat of radiologists being sued. This threat has reached such a level that for the first time, radiology…
Under constant and continuing debate, and given the increasing use of CT and interventional imaging, the issue of radiation dose management was the focus of an ECR session with Dr Manthos Koutalonis, Medical Physicist at the Barts and The London NHS Trust – Radiation Safety Group, as moderator and presentations by three key speakers.
GE Healthcare is highlighting advanced solutions that drive the efficiency of diagnostic imaging at the European Congress of Radiology (ECR), 2010. Complementing the company’s ‘healthymagination’ initiative of reducing healthcare costs through timely care, GE Healthcare is highlighting a range of Computed Tomography (CT) imaging solutions including Adaptive Statistical Iterative…
An estimated 70 million CT scans are performed annually in the USA, a threefold increase since 1993. US physicians rely on CT scans and other diagnostic imaging procedures to make accurate and speedy diagnoses and, until recently, they have not questioned the radiation dose exposure the patient receives. However, this attitude is changing, as physicians and other medical professionals realise…
He literally wrote the book on the subject, so when Jean-Louis Sablayrolles MD, states that low dose computed tomography angiography (CTa) represents a ‘great revolution in cardiac imaging,’ his words carry the weight of deep clinical experience.
Digital mammograms deliver an average of 22% less radiation than film mammograms, according to a study partially funded by the National Cancer Institute and published in the American Journal of Roentgenology, Reuters reports. For the study, researchers analyzed the results of the 2005 Digital Mammographic Imaging Screening Trial involving 49,528 women. That trial found that digital mammograms…
A large proportion of patients who undergo abdominal/pelvic computed tomography (CT) receive unindicated and unnecessary additional image acquisition resulting in excess, avoidable radiation exposure, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
There's no reason to forgo a needed radiation-based medical procedure because of concerns about cancer risk, according to the October issue of Mayo Clinic Health Letter. While the volume of radiation-based tests and procedures has increased in the past three decades, scientists haven't proven that the low doses of radiation used in medical settings actually increase cancer risk.
IMRT is an evolving method of treatment for complex forms of cancer. Although patients benefit from treatment, a precise evaluation of that benefit and overall cost-effectiveness of the method is still an uncertain science. Mark Nicholls reports
