Along with a high local resolution, the cardiac CT imaging also requires a high time resolution where the image data acquisition must be synchronised with the cardiac cycle by means of parallel ECG recording, and the measuring volume must be acquired in a single breathhold cycle. The multi-slice CT copes well with these requirements as it allows for acquiring continuous volume data sets of the…
The evaluation of the size and function of the left ventricle in patients with suspected heart disease is a central diagnostic problem. In contrast to other methods of evaluating left-ventricular function (e.g., angiocardiography, right-sided heart catheterization, radionuclide ventriculography or MRI), transthoracic echocardiography is a widespread and readily available procedure that is not…
Multislice computed tomography (MS CT), which was introduced to clinical imaging as fourslice detectors in 1998 has fully proven its superior performance over conventional scanner technology. For example, it provides optimized resolution of detail and increased scan speed. Simultaneously, this technology has opened new indications for computed tomography, for example, in heart imaging. However,…
Tissue Doppler Imaging (TDI) and contrast echocardiography open up new possibilities for exactly representing and assessing functional cardiac disturbances. This was the topic discussed by Dr. Harald Becher of John Radcliff Hospital, Oxford, and Dr. Jörg Strotmann of the University Clinic Würzburg in the framework of the Toshiba workshop “New approaches in echocardiography” at the European…
It has long been known that remaining at high altitudes leads to an increase in pulmonary arterial pressure caused by hypoxia. Its effects on cardiac function have also been considered well documented. The increase in pressure in the pulmonary circulation causes an enlargement of the right ventricle and thereby causes a displacement of the left ventricle that is accompanied by a relaxation…
Because of the rapid technical and scientific development over the past few years, multislice computer tomography of the heart has become increasingly established in the clinical routine. This requires, among other things, knowledge of the anatomy of the coronary arteries, the meaningful evaluation of the calcium score and the appropriate reproduction of the function of the left ventricle.
It has long been known that hypoxia at high altitudes leads to an increase of pulmonaryarterial pressure. For sensitive persons, one crucial factor for the development of HAPE is the overwhelming rise in pressure in the pulmonary circulation. Using right heart catheterization average pulmonary-arterial pressures of 60 mmHg were encountered in earlier studies of HAPE patients. A pressure increase…
Located in the southeastern part of Brussels, the “Cliniques de l'Europe” is a group of three clinics: Saint Elisabeth, Deux Alices and St. Michel. Over a period of several years, our organization has been restructured and adapted to the needs of this facility which serves a local population of approximately 250,000. Cliniques de l'Europe has at its disposal a complete range of dedicated…
Spiral computed tomography first allowed the seamless acquisition of entire volumina without first separating them into individual slices. With the newest generation of MSCT devices having the 16-slice technology, short gantry rotation time of < 0.5 seconds, and a high performance processor, it is now possible to acquire large amounts of data in a short period of time with high spatial and…
63-year-old male with stable angina. The coronary angiogram showed vessel disease with significant stenosis in the proximal LAD and in the middle of the LCX. PCI with stent performed the day before the CT Angio. The patient was referred to the Aquilion 64 for follow-up.
Among invasive cardiac catheterization diagnostic methods selective coronary angiography is the gold standard for directly visualizing the coronary system. It allows a definitive and precise diagnosis of coronary heart disease and thus serves as the rational basis for further revascularization procedures.
The goal in cardiac computed tomography is to obtain motion-free images of the beating heart. A newly launched software from Toshiba called PhaseXact introduces advanced features to reach this goal fully automatically.
Dyssynchrony Imaging (DI), Toshiba's novel Doppler technology, is used as a quantitative clinical tool for rapid assessment of dyssynchrony in patients with suspected myomechanical dysfunction. From the parasternal short axis view, DI is applied by Toshiba's exclusive “angle-correction” technology and in apical views by standard Doppler imaging. Thus, DI permits evaluation of virtually all…
Diagnostic imaging is of particular value in investigating ischaemic cerebrovascular accidents since, due to the rapid progression of cell destruction in the region of the cerebral infarction, the radiologist is faced with urgent questions regarding a possible procedure. These questions may be answered particularly well using computed tomography (CT). The following article provides an overview…
Ongoing refinement of modern spiral multi-slice CT scanners offers the opportunity for very high temporal and spatial resolution thin-slice data set acquisition. The econstruction techniques offered (multisegment reconstruction) result in improved temporal resolution while simultaneously reducing the effective exposure time to 40-200 ms and thus also reducing motion artefacts. The SURECardio…
The goal of CORE64 is to evaluate the diagnostic accuracy of computed tomography angiography (CTA) compared to coronary angiography (CAG) in patients with suspected coronary artery disease (CAD).
Various record systems that transfer patient data directly from an emergency site to physicians' monitors for diagnosis of cardiac incidents were demonstrated at MEDICA 2006.
Almost one in three people over 55 will develop congestive heart failure, research has revealed. The Rotterdam Study, a prospective population-based study of cardiovascular and other diseases in the elderly, monitored 7,983 inhabitants of Ommoord, a Rotterdam suburb (source: Eur Heart J 2004: 25, 1614-19).
RSNA 2006 - that means six days of educational programmes, 1,625 scientific papers, more than 300 refresher courses and 738 technical exhibits on 514,800 square feet. The 92nd Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA) which takes place in Chicago from 26 November to 1 December will once again be the highlight of the year for those who are in touch…
New pulsatile heart pumps (ventricular assist devices - VAD) can remain in the body as a permanent heart support.
There is no lack of IT and software solutions for putting digitisation and networks into practice; however, many hospitals wonder how the implementation will work in practice and whether the investment will prove successful.
To learn more about the presence of Philips in healthcare - and particularly cardiology - our Netherlands correspondent visited the company in Amsterdam.
The objective of the CNIC is to lead cardiovascular research in Spain and establish itself as a leading international centre.
Freezing abnormal electrical pathways in the hearts of young patients may be a safer alternative to zapping them with powerful radiofrequency probes to treat tachycardias and other arrhythmias, according to Dr Fabrizio Drago, of the Bambino Gesù Hospital, Rome. ‘If you have a child with a supraventricular tachycardia due to a re-entry circuit, or a target very close to the atrioventricular…
Scientific meetings held since 1998 at Alpbach, Germany, have attracted the sponsorship of leading associations and companies such as the Philip Morris External Research Programme, the Donors Association of German Science, Swiss National Fund, the German Heart Centre Foundation, Berlin, and Philips Medical Systems. At the 4th Alpbach Meeting, which focused on Magnetic Resonance, Contrast…
