Due to echogenicity differences in comparison with the surrounding liver tissue conventional B-mode-imaging sonography permits the unambiguous classification of the frequently occurring typical liver cysts (criteria: round, echo-free, smoothly demarcated, with edge shadows and sound through transmission) and calcifications (highly reflective, acoustic shadows). The detection and characterization…
With an innovative technique called multiplexing, the data collection speed of CT scanners may increase by hundreds of times with the result of better and faster imaging and potentially lower x-ray exposures.
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…
Modern oncology with its improved options holds out prospects for many novel curative and palliative procedures. By adopting a multidisciplinary approach to diagnosis, treatment and follow-up care these prospects can become reality, with radiology playing a pivotal role. This role encompasses imaging diagnostics for all tumour entities as well as diagnostic and therapeutic interventions.…
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…
Modern imaging modalities are increasingly playing a role in planning therapy for aortic diseases and in follow-up exams after surgery or endovascular intervention. The methods employed for minimally invasive endovascular therapy have been continually improved in recent years and are now being used by vascular surgeons or radiologists to treat thoracic, thoracoabdominal and abdominal aortic…
Pain management due to spinal disorders and perispinal conditions represents an important health issue for the 21st century. Over the past decades, growing disability resulting from back pain has enabled development of alternative techniques and treatments to surgery. CT fluoroscopic needle guidance has allowed decreasing risk and maximizing patien comfort in spinal minimal invasive treatments.
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.
A 152-bed private hospital in a small town as the first Austrian hospital to invest in an Aquilion 64 CT scanner for routine operations? That seems unusual - but only at first sight. So let's have a closer look and see what happened in scenic Villach in Carinthia. The investment by the Villach Private Hospital (Privatklinik Villach) - a member of the HUMANOMED Group - in state-of-the-art medical…
Pediatric cardiovascular disorders are extremely complex in nature and present with a widely variable array of abnormal anatomy. Imaging these disorders presents a unique set of challenges for the cardiovascular team. Complex anatomical variations require detailed volumetric image interpretation with high spatial and temporal resolution. In addition, the patients are invariably young. They may…
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.
BMI Healthcare is installing Toshiba's Aquilion 64-slice CT scanners in five of its 49 acute care private patient hospitals (The Alexandra Hospital, Cheadle; Bath Clinic, Bath; Blackheath Hospital, London; Meriden Hospital, Coventry; Priory Hospital, Birmingham) as part of a £7.5 million spend on diagnostic imaging technology.
The Aquilion LB (Large Bore) sets yet another milestone in the success story of computed tomography, providing a new dimension in diagnostics and treatment.
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.
Excluding pulmonary coin lesions potentially caused by metastasis of extrathoracic malignant tumours or as the principal indication of early lung carcinomas is one of the most frequent tasks in plain film imaging and computed tomography examination of the thorax.
CT assisted dynamic perfusion imaging (perfusion CT, PCT) has evolved in recent years with the introduction of the multi-slice spiral technique, the use of study protocols with lower injection rates and improved evaluation programmes.
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…
In the past, native computed tomography of the neurocranium (CCT) was often the only procedure to diagnose a stroke. Technical limitations of previous generations of scanners made their use impractical for complementary methods of visualising blood vessels or for perfusion imaging. With the introduction of multi-slice spiral CT these technical limitations disappeared and both perfusion CT (PCT)…
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).
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…
Already in 1993, the world market for contrast media was thought to be worth $ 3 billion. In 2001, an astonishing 12.2 million contrast medium-supported CT studies were carried out in Europe alone. Currently, the overall sales of contrast media are estimated to rise to $ 915 million in Europe in 2008.
This was the motto of the ECR 2007 in Vienna, where a group of high-ranking experts discussed diseases of the 21st century; research competition between the US and Europe; the conditions needed to progress leading medical R&D - moderated by Congress President Professor Christian J Herold.
In 2001, an astonishing 12.2 million contrast medium-supported CT studies were carried out in Europe alone. Currently, the overall sales of contrast media are estimated to rise to $915 million in Europe in 2008.
When the Siemens board of directors announced its decision for the new Siemens CEO on Sunday, the economic world was surprised: Not only that the name Peter Löscher was never mentioned in the previous discussions about a successor of Klaus Kleinfeld, but hardly anybody knew Loescher´s name in any enconomic context.
Dr A Tamosiunas, Associate Professor at the Radiology Centre in the Medical Faculty at Vilnius University, Lithuania, and Director of the Radiology Centre at Vilnius University Hospital, discusses the present situation and future development of the radiology services in Lithuania with EH correspondent Andrius Vagoras
