Three questions for WFUMB Honorary Lecturers …
World of Ultrasound met Prof. Ioan Sporea, Prof. Gebhard Mathis and Prof. Byung Ihn Choi to ask them three questions.
From tissue uniformity to volume imaging
Explaining the value of the iU22 xMATRIX ultrasound system, Philips describes its new array transducer within the system – the X6-1 PureWave xMATRIX – as revolutionary.‘It harnesses the power of over 9000 active elements, more than 35 times greater than conventional transducers, to capture crisp, high-resolution images of even technically challenging patients,’ the company points out,…
Papworth Hospital: A constant continuing success
Recent events have again underlined the reason why Papworth Hospital in ambridgeshire, England, maintains a enowned international reputation for cardiac and thoracic procedures. As Britains largest specialist cardiothoracic hospitals, over 2,000 major heart operations were performed there in 2010. In the year ending 1 April 2011, 824 patients had coronary bypass operations, including urgent,…
Satisfaction in everyday life may protect against heart failure
While depression and anxiety have long been recognised as risk factors for heart disease, there is less certainty over the beneficial effects of a ‘positive’ psychological state. Now, according to results from a study of almost 8,000 British civil servants, published online by the European Heart Journal, researchers report that a satisfying life is indeed good for the heart.
Investigating treatment options for atrial fibrillation
The first patient has been enrolled for the largest pan-European study to determine whether an early comprehensive rhythm control strategy for the treatment of atrial fibrillation (AF) will benefit patients. Patients with recent-onset AF at risk for stroke or death are eligible for the trial. The researchers plan to enrol more than 3,000 patients from 200 centres in 11 European countries.
Building human hearts on an assembly line
An artificial heart will be implanted in a patient before the end of 2011, marking a milestone in medicine. The developers are now accelerating plans to manufacture thousands of these mechanical hearts for patients worldwide, reports John Brosky
MRI and plaque imaging
Cardiovascular disease is the leading cause of death in industrial nations. More than 50 percent of those deaths are associated with pathologies of the coronary arteries, despite the fact that luminal obstructions that lead to myocardial infarction or ischemia do not occur out of the blue. The initial symptoms are preceded by a whole slew of arteriosclerosis stages and the early detection of…
Trends in stents and balloon angioplasty
Stent fever, first diagnosed in 1997, has been spreading throughout the medical world – fuelled by new technologies, says Holger Zorn
A time to tackle controversies face-to-face
A hefty debate on controversial issues in cardiology is the definite intent of Congress President Professor Michel Komajda and the ESC 2011 congress organisers. To that end, he plans to open the event with a focus on disagreements among cardiologists over treatment methods. This is not the only promise of a lively meeting for congress participants, as Prof Komajda explained in conversation with…
RESPONSE trial results
Studies show that when a nurse follows patients after a cardiovascular crisis those patients stay healthier, live longer and reduce the risk of returning to hospital. Now the challenge is how to convince insurers to pay for this care, reports John Brosky.
Transcatheter aortic valve implants
Although transcatheter aortic valve implantation (TAVI) is increasingly the most used surgical procedure in Germany, only two products have been approved for routine use. Although this has prompted other medical device manufacturers to go into action, according to Professor Justus Strauch, head of cardiac surgery at the Klinikum Bergmannsheil, Bochum, no one has yet taken the lead in this…
The New York Academy of Sciences Conference
This two-day international scientific symposium follows two previously successful conferences held by the New York Academy of Sciences (NYAS), ‘la Caixa’ Welfare Projects, and the International Centre for Scientific Debate (ICSD) for researchers, physicians, scientists and representatives of the related industries, working in cardiology, vascular disease, inflammation, regenerative medicine,…
Elastography in breast ultrasound
In recent years, the technique of breast ultra-sonography has become an essential procedure in the diagnostic evaluation of breast tissue. The improvement of ultrasound technology, especially with regards to the high resolution of modern devices and the use of colour Doppler sonography, has made this technique indispensable in our daily routine. Although the value of conventional breast…
High-end ultrasound at Sahlgrenska University Hospital
Sahlgrenska University Hospital provides emergency and basic care for the 700,000 inhabitants of the Gothenburg region. It also provides highly specialised care for the 1.7 million inhabitants in Sweden’s west because, in this country, endoscopic ultrasound examinations are only provided in university hospitals. Thus Sahlgrenska’s physicians receive referrals of difficult diagnostic cases…
True values versus relative Measurements
Detecting prostate cancer with transrectal ultrasound using strain elastography is quite tricky: it works by applying pressure to the transducer to measure relative stiffness of tissue, Professor Correas points out and states that ‘more than 80 percent of prostate cancer develops in the peripheral zone which is against the rectal wall. If we apply pressure to this zone the deformation of the…
‘Our products are competitive’
In recent years the ultrasound division of Siemens Healthcare appeared to be a Sleeping Beauty slumbering on in the shadow of large slice imaging equipment such as PET/CT and MR/PET, the medical technology giant’s favourite daughters. With many of the world’s wealthy princes, particularly from India, Brazil, China, and so on, knocking on Siemens’ doors, the giant has at last decided to wake…
Determining the site of deep brain implants
Uncontrollable convulsions, tremor or spasms can considerably impair the lives of neurodegenerative disease patients. Deep brain stimulation (DBS) – for which tiny electrodes are implanted in the brain to stimulate the target areas continuously with electrical impulses – can significantly reduce the movement disorder.
CT, PET-CT, MRT and transthoracic ultrasound in lung cancer staging
Dr Helmut Prosch, at the University Clinic for Radio-Diagnostics, Vienna, Austria, is examining the role of imaging in lung cancer diagnosis and staging. The key message of his presentation in the session EUS and EBUS vs. CT, MR and PET-CT in the staging of lung cancer is that the modalities do not compete with one another – as the title suggests – but are perfectly complimentary in the…
Ultrasound and the lung
Lung ultrasound is a technique with widespread uses and advantages in a range of areas from critical care through to less urgent medical areas. Most of all, it is of particular help in the rapid diagnosis of acute respiratory failure. During a session at WFUMB, its benefits and the latest techniques will be outlined by medical intensivist Dr Daniel Lichtenstein -- Lung Ultrasound in Acute…
From punch to vacuum to RF-guided breast intervention with ultrasound
More than 90% of patients who present with suspect or highly suspect breast lesions (BI-RADS categories 4 or 5) now undergo biopsies. Further treatment is only carried out after the precise histological clarification of the tissue sample is obtained. The intervention is routinely carried out via ultrasound guided punch biopsy. Thanks to new techniques the procedure is now becoming even more…
51 live scanning sessions at WFUMB
Although space limitations have reduced the number of live scanning sessions at past World Ultrasound Congresses, this year greater space at the Vienna venue has enabled the organisation of 51 live scanning sessions by Dr Christian Aiginger, consultant internist at the St. Josef Hospital Vienna Auhof, with Dr Helmut Prosch, Consultant at the Department of General Radiology and Paediatric…
The breast ultrasound Champion League
Since 1991 the International Breast Ultrasound School (IBUS) has indefatigably promoted progress and quality assurance in breast ultrasound -- a good reason for IBUS to celebrate its 20th anniversary during WFUMB.
Staying on the right side of the law
High flexibility and live conditions contribute towards the high popularity of image-guided interventions, now performed under ultrasound control in 80-90% of cases. However, although minimally-invasive examinations are based on high standards of medical safety, complications can arise that could ultimately lead to litigation. Thus, experienced ultrasound operators would be wise to know the…
Fusion and Fly Thru - the new Aplio 500
Catastrophes draw people closer, as demonstrated by the development of the new high-end ultrasound scanner Aplio 500 from Toshiba. The clinical evaluation period took place during the tsunami and the nuclear catastrophe in Fukusima. Professor Thomas Fischer at the Radiological Institute, Charité Clinic in Berlin, was impressed by the enormous commitment shown by the Japanese firm’s engineers…
From pre-natal diagnostics to 3-D baby-facing
Prenatal ultrasound images are the first images we see of new humans. But the prenatal ultrasound first carried out by Professor Ian Donald in the late 50s has little to do with today’s potential with 3-D and 4-D imaging with Doppler and colour Doppler. The three tightly linked disciplines gynaecology, prenatal medicine and obstetrics would now be inconceivable without ultrasound
