Women could be undergoing unnecessary breast surgery as a result of having magnetic resonance imaging, says an expert on bmj.com. In the last decade, says Malcolm Kell, Consultant Surgeon and Senior Lecturer at the Eccles Breast Screening Unit at University College Dublin, MRI or magnetic resonance mammography has become the most favoured type of investigation for high risk patients when combined…
Radiologist Dr Karl-Friedrich Schünemann works in a group* practice in the small German city of Paderborn. Focusing on sports injuries and using MRI, CT and X-ray, the specialist medical team provides services such as neuroradiology, orthopaedics and CT-guided pain therapy. ‘The fact that we count a number of professional athletes among our clients also attracts many amateur athletes who…
No white lab coats anywhere; instead men in hard hats, equipped with hammers and drills. The Düsseldorf University Hospital’s Cardiology Pneumology and Angiology Clinic is a construction site, but once the workmen have packed up their tools and removed the scaffolding the view to the human heart will be unobstructed and clearer than ever before. Here, innovative patient care and a highly…
The focus on Coronary artery disease – from genes to outcomes at ESC 2010 underlines the importance of CAD diagnosis on the scientific agenda. During the session ‘Multi modality imaging to detect coronary artery disease’, chaired by Professor JJ Bax, of the Cardiology Department at Leiden University Medical Centre, the Netherlands, experts will discuss, for example, the advantages of the…
Not only is heart failure one of the single biggest causes of morbidity and mortality in man, but the incidence of the condition is steadily increasing. Rising to this challenge, innovative medical diagnostic techniques with ever greater performance are constantly being introduced so that early, unambiguous detection of the underlying condition is now possible, enabling the prompt initiation of…
Early problems of ultra-high field Magnetic Resonance Imaging (MRI) have been overcome by successful development of adequate hardware. In consequence big efforts have been achieved in structural imaging, as well in functional imaging. Basic scientists and physicians who work in ultra-high-field MRI in Europe and the USA, met at the Berlin Ultra-high-field Facility (BUFF), in the Max Dehlbrück…
Modern magnetic resonance (MR) tomographs with very strong magnetic fields produce images of steadily increasing precision and are currently gaining more and more importance in radiological diagnostics. In conventional MRI the patient lies in a tunnel, which many people find difficult or even impossible to do, given a scan time of approximately 20 minutes. Physicians of the Joint Radiology…
During the opening of the fully renovated InHealth MRI Centre at Mayday Hospital in Croydon, UK, three renowned Harlequin rugby players demonstrated just how ‘open’ the newly installed Oasis 1.2 Tesla highfield open MRI system is. Rugby players are notably large. This Hitachi system can accommodate patients who cannot fit into a conventional closed bore type of magnet.
Hitachi Medical Systems UK has been awarded the contract for OASIS™ 1.2 Tesla high-field open MRI by InHealth MRI Centre at Mayday Hospital, Croydon – the high performance system with a truly open architecture available in the UK. This unique product combines unrivalled patient comfort together with first class imaging comparable to that of a closed bore system.
Intra-operative MR imaging is still uncommon in Europe – particularly in neurosurgery. One of the first neurosurgery departments to work with a 3-T MR is in the Central Military Hospital in Prague. The experience and initial clinical findings from treating more than 300 patients, over a two-year period, was reported at this year’s ECR.
Molecular imaging, the discipline that unites molecular biology and in vivo imaging technologies to assess biological activity in the body, promises to open up ‘…an entire new universe,’ declared Dr Ralph Weissleder, of the Centre for Molecular Imaging Research at Massachusetts General Hospital, USA, in the journal Radiology. That was just one decade ago. And he was right. It has indeed…
The number of MRI scans carried out on arm and leg joints in a specialised radiology practice is high and constitutes a significant part of MRI scanner use. Such is the case at the Remigius Ärztehaus in Leverkusen and the RNR Dortmund MVZ, both specialist surgeries within the RNR Association, one of the largest radiological networks in Germany.
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.
Siemens Healthcare was presenting its latest solutions for the early detection and treatment of breast cancer at the German Radiology Congress in Berlin. These Breast Care Solutions include a variety of imaging procedures, such as ultrasound, mammography, and magnetic resonance imaging (MRI), supplemented by IT and laboratory diagnostic solutions. Siemens places special focus on the third…
2010 workshop in Aachen, Germany, in March, were welcomed by Professor Thomas M Deserno, head of the Medical Informatics Department at RWTH Aachen University and organiser of what turned out to be an ‘outstanding’ scientific programme.
Performing pre-operative breast MRI in all women with invasive lobular carcinoma (ILC) can reduce the need for re-excision, according to a study conducted through two major cancer centres - the Radboud University Nijmegen Medical Centre and the Netherlands Cancer Hospital/Antoni van Leeuwenhoek Hospital.
During conventional electro-cardiology, interference from electromagnetic fields (EMFs) tends to diminish image quality due to cardiac motion. To exclude that interference an acoustic cardiac triggering (ACT) approach, also called MR stethoscope, has been developed to trigger cardiac MRI at 7-Tesla.
‘There are few reasons to deny a patient an MRI scan, and nearly all of them are having a pacemaker,’ said Pierre Bordachar MD at the Centre Hopitalière Universitaire (CHU), Bordeaux, France. Yet one-in-five pacemaker patients will require an MRI scan within the first year of receiving a pacemaker, while more than half of all pacemaker patients will need such a scan at some later point in…
Increasingly, hospitals have to find ways to optimise the capacity, efficiency and utilization of their MRI services. David Wormald, Integrated Assistant Vice President for Diagnostic Services at Hamilton Health Sciences & St. Joseph's Healthcare, Hamilton, Canada, knows this problem in and out – and a few solutions on top of it.
At Mannheim University Medical Centre five MR units are currently installed - the Magnetom Tim Trio, 2 x Magnetom Avanto, Magnetom Sonata and the new Magnetom Skyra, which was presented at the RSNA 2009 and is equipped with completely new software.
Spurred on by the success of PET/CT and the collaboration of radiology and nuclear medicine, further techniques such as PET/MR or SPECT/CT have been developed, bringing imaging modalities and nuclear tracers and technologies closer. The time has now come to identify applications for hybrid modalities and train future users, as was explained today by a pannel of specialists led by Prof Thomas F.…
Since June 2009, the focus of research in the European Network for Cell Imaging and Tracking Expertise (ENCITE) has been on finding biomarkers to aid cell transplantation. Funded with €11 million from the European Commission (EC), this major project that runs until 2013, involves 10 countries. Their work is coordinated by the European Institute for Biomedical Imaging Research (EIBIR) network,…
Physicians, over many centuries, have depended on the sense of touch as their hands on method to detect diseases in many body areas. This technique is called palpation. However, though it was known that abnormalities in the stiffness or mechanical environment in tissue may have a profound impact on how many diseases progress, conventional imaging modalities could not display tissue stiffness in…
Cardiologists are looking beyond on-screen images of the heart to extract data behind these scans that describe coronary dysfunctions and can reveal hard evidence of the cause of disease reports John Brosky.
On show in the MR sector at this year’s RSNA was the Optima MR450w wide-bore system manufactured by GE Healthcare. Built on a fully redesigned MR platform, this offers a range of advanced new functions, which, GE reports, makes it ‘a workhorse system for practices of all sizes and specialties’.
