Vascular Recognition Imaging (VRI) is a low MI broadband colour Doppler method that images the interactions of Sonovue with microbubbles in a non-destructive manner as perfusion images of a quality never before achieved. The perfusion image represents the low velocities of unmoving or barely moving microbubbles as green-coded tissue perfusion, while the higher velocities of the veins and arteries…
Most babies are born healthy, but there is still a small risk for all women to give birth to a baby with some type of anomaly. Ultrasound has proven to be one of the most reliable procedures to prenatally diagnose some of these conditions. Ultrasound can be used during the entire pregnancy, but in the first trimester ultrasound examinations are, as a rule, used to exactly calculate the pregnancy,…
In Johns Hopkins therapeutic radiology, we perform 2,600 procedures in neurointervention and 14,000 peripheral interventions each year, totalling over 16,000 image-guided procedures a year in 14 rooms. We changed our approach to image guided therapy in June 2001, when we installed a new O.5 mm multidector CT (Aquilion, Toshiba America Medical Systems) and two 3D visualization workstations (Vital…

The new Centre for Image Guided Therapy (IGT) at The Hospital for Sick Children allows surgeons and interventional radiologists to do something that's never been done before - work side-by-side when diagnosing and treating children. A total of 4 interventional suites were equipped…
Without doubt, the B-mode imaging is the most important examination method in prenatal ultrasound. Well over 90% of detectable congenital anomalies can be recognised using the two-dimensional realtime imaging method. Hence, paramount importance is certainly ascribed to the quality of the B-mode image in an ultrasound system. In addition, other ultrasound modalities help us to considerably enhance…
Pediatric imaging presents many unique and difficult challenges to the radiologist. Correct and rapid diagnosis is extremely important in pediatric imaging and to that end we constantly strive for tests that offer more information, accuracy and versatility. However, it is also our duty to provide tests that are safe and minimise exposure to ionizing radiation. In recent months there has been…

The most advanced 32-slice CT scanner available, the Aquilion provides increased patient comfort and the most flexible choice of speed and accuracy in CT scanning.
Further developments in computer and detection technology over the last few months and years have made it possible to overcome, to a large degree, the previously limitations of medical computer tomography in spatial and temporal resolution, and thus to permit “detail-true” representation of the beating heart. The diagnostic workflow and computer-tomographic diagnosis of the heart using the…
The Amphia Hospital in the Netherlands is an amalgamation of three hospitals: the Molengracht and the Langenberg in Breda and the Pasteurlaan in Oosterhout, with a total capacity of 1100 beds. At present, these hospitals are not specifically specialised and consequently there is considerable staff movement from one facility to another. However, in the near future a high-tech facility will be…
Since the beginning of the 90s, sonography has been a solid diagnostic pillar in ophthalmology centers, but it is also used by related medical disciplines, such as pediatrics, whose patients require ophthalmological treatment. For all age groups, the fundus of the eye, and especially the optic disk, is well-suited for high-frequency sonography with linear transducers. This type of examination…
The rare disease Takayasu's arteritis (TA) belongs to the vasculitis group of diseases and is also known as inflammatory aortic arch syndrome or as pulseless disease because of its typical clinical picture. The pathological-anatomical manifestations include inflammatory transformation of the media and adventitia with the appearance of giant cells, hence the term giant cell arteritis is also used.…

The Aquilion 64 demonstrates Toshiba's in-depth industry knowledge and desire to deliver leading-edge CT technology and applications to the medical…
Sonography is an increasingly used examination procedure for the diagnosis of illnesses of the hand, especially of the soft tissues. Sonoanatomic assessment of the functional structures (Tab. 1) sometimes allows the exclusion of various differential diagnoses. However, this requires quite a bit of experience on the part of the examiner. The assessment of the peripheral nerves can be difficult -…
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…
Imaging of blood flow with colour Doppler sonography is an established method in prenatal medicine. Today, there are several techniques which offer colour visualisation whose quality is on a par with that of the B-mode. One example of such a technique is Advanced Dynamic Flow (ADF). Looking at two cases, we will describe the clinical use of ADF to visualise fetal vascular tumours. The quality of…
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…
In 1998, the radiology department of the Kopernik hospital had to be modernized. The owner of the hospital, the province of Lodz, couldn't afford such an investment and as a public institution the hospital itself couldn't take up a loan. Dr. Tazbir came up with the idea to found a limited liability company in order to be able to raise the money.
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…
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.…
Echo-enhanced ultrasound is a newly available imaging modality for use in the differential diagnosis of pancreatic tumours. Ductal carcinomas are often hypovascularised compared with the surrounding tissue. On the other hand, neuroendocrine tumours ar hypervascularised lesions. Tumours associated with pancreatitis have a different vascularisation pattern depending upon their inflammation and…
In the Caucasian population, subarachnoid hemorrhage (SAH) due to a ruptured intracranial aneurysm is seen with an incidence of 6 to 8 per 100,000. In some specific countries such as Finland and Japan these numbers rise to 20 per 100,000. 60% of patients presenting with an aneurysmal SAH are female. The presenting symptoms are: thunderclap headache in combination with (temporary) loss of…
Breast cancer is the most frequently occurring malignant tumour worldwide. Of the more than one million newly diagnosed cases each year, the incidence among women in Germany alone is more than 50,000. That means that every tenth woman is stricken by breast cancer at some point in her life. It numbers among the most frequent causes of death by cancer 1,2,3 , with the average age of onset being…
For decades, non-invasive cardiac assessment has been at the center of interest. Non-invasive imaging modalities, such as MSCT, MRI, SPECT, PET, and echocardiography, provide valuable cardiac information, and all have been used to measure cardiac morphology, function, perfusion, viability of myocardium, and coronary anatomy for clinical management and research. The last decade brought major…
