Seasons change - and so does our mood. When days become shorter and hours of sunlight become fewer some of us suffer from seasonal depression. Brain scans taken at different times of the year brings it to light: sun makes happy.…
Transapical aortic valve implantation (TA-AVI) is a new therapeutic strategy, which has been implemented successfully into clinical practice in several hundred patients suffering symptomatic aortic stenosis and an increase perioperative risk during the past two years. The Edwards SAPIEN™ prosthesis has been used.
Catheter ablation is still associated with a substantial amount of complications, and more failure then sometimes reported. Perforation with catheters is especially important in atrial fibrillation. Robotic navigation could reduce these complications.
Carestream Health's engineers created the first wireless DR detector which is not bigger than a standard cassette and can therefore withstand the challenging environment of a modern x-ray department. The rugged detector, case, and internal components are made to produce DR images of high quality under real-life x-ray department conditions.
Intima media thickness (IMT) is a valuable research tool that can be used as surrogate end points in clinical trails, says Professor Stefan Agewall.
Terry Shivo was 27 when she collapsed. Paramedics found neither respiration nor a pulse. Almost three months later her eyes had opened, but she was not conscious. She has a sleep/wake circle and sometimes appeared to smile - she was in a vegetative state.
Martini Clinic, in the University Hospital Eppendorf (UKE) campus in Hamburg, is one of the world's major centres for nerve-sparing prostatectomy. The Martini physicians not only specialise in surgical intervention but are also at the cutting edge of diagnostics, being among the few in Germany to use sono-elastography, an innovative tool to detect prostate cancer. We asked Dr Georg Salomon (GS),…
Siemens Healthcare will show its Acuson S2000, the first ultrasound system in the new product series S, at the ESC*. The system platform includes integration of the newest technologies to optimise workflow, e.g. comprehensive software applications such as new software for breast imaging.
`High performance systems need not be large,´ says Aloka, manufacturer of the new compact ProSound a7, which produces high-resolution images yet can be used in areas with little spare space. `Broadband Harmonics provides high sensitivity and penetration that is comparable to fundamental-frequency imaging resulting in a significant improvement above standard harmonic imaging,´ Aloka reports.
Philips has added a new platform to its HD ultrasound products - the HD15 - which aims to provide small hospitals, clinics and private practices with advanced image clarity and broad application support for everyday use.
What is the role of vascular ultrasound in stroke prevention? Asked by Karoline Laarmann of European Hospital, Professor Christian Arning MD, Medical Director of the Neurology Department at Asklepios Klinik Wandsbek, Germany, and Deputy Chairman of the German Society of Ultrasound in Medicine (DEGUM), gave an unequivocal answer: crucial - but only if the sonographer is properly qualified.
Although ultrasound imaging is a very powerful imaging modality it is mostly under-used Ultrasound combines several very appealing characteristics. It is among the non-invasive imaging modalities, indeed it is really non-invasive. Similar to MRI, no harm to the patient can be caused by ultrasound.
Almost 25 years ago Michael Harrison of the University of California, San Francisco (UCSF) operated on the bladder of an unborn child. Almost eight years later, surgery was carried out on the diaphragm of an unborn child. His approach was controversial: a paediatric surgeon opened the abdomen and uterus of the pregnant woman, lifted out the foetus, performed the surgery and returned the foetus to…
An emerging discipline of noninvasive cardiac imaging, molecular imaging, has evolved constantly in the last few years and is increasingly being translated from the preclinical to the clinical level. Molecular imaging allows for unique insights into specific disease mechanisms and holds great promise to change the practice of cardiovascular medicine by facilitating early disease detection,…
While treadmill exercise stress testing is essential to detect cardiovascular disease, gaining clear cardiac images at peak stress level are not easy to gain using standard testing procedures. Now, however, researchers at the Ohio State University Medical Centre have designed equipment to provide high-resolution cardiac images at a critical testing stage, with results in under one hour.
Atlanta-based Velocity Medical Solutions launched VelocityAI, its new molecular imaging software, at the 2008 American Association of Physicists Medicine (AAPM) in July.
Last October the Food and Drugs Administration (FDA) added a black box warning on ultrasound (US) contrast agents used in echocardiogram imaging examinations, around 200 reports of serious allergic reactions were received. Problems included cardiac arrest as well as breathing difficulty and seizures; seven of the cases resulted in death.
The belief that iodinated contrast agents can induce nephropathy has been held for many years, even though most of the clinical literature has not been able to distinguish contrast-induced nephropathy from other causes of the condition.
The drug information system AiDKlinik developed by Dosing GmbH is a software solution for the server-based intranet for medication dosing.
The first robotised tele-ultrasound examination has been performed by participants in the European Mobile And Robotised Tele-echography (MARTE) project, in collaboration with Robosoft, specialist in the development and production of service robot systems.
Pegasus/Heartview LLC has announced that clinical studies of its HeartVue 6S Heart Screening System - which obtained CE Mark Approval in Europe almost two years ago - have been completed according to FDA guidelines, as a pre-marketing condition for release in the USA.
St. Jude Medical, Inc. has received European CE Mark approval and US Food and Drug Administration (FDA) clearance for its Epicor LP cardiac ablation system, a second generation technology that uses HIFU (high intensity focused ultrasound) for surgical ablation of cardiac tissue to disrupt abnormal cardiac electrical impulses.
Stefan G Ruehm, Kambiz Nael, Derek Lohan and Henrik J Michaely* describe impressive images that benefit patient treatment
