The upper gastrointestinal (UGI) team at Milton Keynes Hospital NHS Foundation Trust has developed a rapid access service for upper gastrointestinal cancers. The new system means that patients are referred directly from their GP to the hospital for an endoscopy.
A German-US R&D collaboration is to commercialize a CT image reconstruction system that will yield enhanced image quality but with a lower radiation dose when compared with standard CT systems. Although initial applications are being lined up in industrial materials testing, talks are already under way with medical imaging vendors keen to exploit the technology in a clinical setting.
In 2008, the European Congress of Radiology (ECR) will include a Special Focus Session titled "Women in Radiology". During an EH interview, Professor Dr Maximilian Reiser, President of ECR 2008 (Vienna, Austria) discussed this and other aspects of the new programme. Russian article
Toshiba America Medical Systems, Inc. introduced the world's first dynamic volume computed tomography system the AquilionONE. This advanced diagnostic imaging system revolutionizes can help reduce diagnosis time for life threatening diseases like stroke and heart disease from days and hours to mere minutes.
The Philips flagship product at RSNA, the 256-slice Brilliance iCT scanner, allows radiologists to produce high-quality images with exceptional acquisition speed, including complete coverage of the heart and brain. It is so powerful it can capture an image of the entire heart in just two beats, while incorporating Philips technology that has reduced radiation doses by up to 80 percent.
Radiologist Dr Myriam Hunink is a Professor in the Epidemiology and Biostatistics and the Radiology Departments at the Erasmus MC in the university medical centre, Rotterdam, the Netherlands, where she is also project leader for several research projects focused on radiology and epidemiology.

Visage PACS/CS, a scalable PACS solution based on web and thin client technology with fully integrated clinical applications, is to be demonstrated at this year's RSNA in Chicago, along with a comprehensive portfolio of life sciences products and services from Visage Imaging, a subsidiary of Mercury Computer Systems Inc.
A comprehensive knowledge of the topographic relationships of anatomical structures is a must for all doctors.
ulrich medical, established 25 years ago, is an independent medium-size medical technology firm with worldwide sales. Among its products are contrast agent injectors for contrast agents used in computer and magnetic resonance tomography.
About 27,000 healthcare professionals from over 100 countries attended RSNA 2006. These included over 5,000 European clinicians. In addition, over 28,000 people from non-US countries manned about 750 exhibition stands.
Comparing radiological practices in Israel with those of Europe and the USA, Professor Graif explained that his country combines both.
For 2 1/2 years we have had the opportunity to use a 64-MSCT in our emergency department at the Brüder-Krankenhaus Trier, the biggest institution of the Brothers of Charity and academic teaching hospital at the University of the State Capital of Mainz.
According to a study from the technology consultancy Frost & Sullivan the market for CT systems in Europe will grow annually by 4% - in 2013 sales will be worth $1.14 billion. Customers' primary request are cardiac imaging applications, but software innovations and improvements in scan time and image acquisition are also distinguishing features of next-generation systems.

Radiotherapy treatment planning relies on transversal CT images. They form a basis for treatment planning, dose calculation and increasingly the plan localization for external radiation therapy, called CT simulation. A dedicated CT scanner for radiotherapy plan simulation is one of the most essential pieces of equipment in a modern radiotherapy department. In contrast to external beam…
The advent of multislice computed tomography has made coronary artery imaging with computed tomography (CT) a clinical reality. When a CT scanner with 16 detector rows is used, scan times are within the breathholding capabilities of most patients. The latest generation of CT scanners with 64 detector rows has reduced the scan time to 6-10 seconds, which is suitable for examining all but the most…
In 1999, the Aquillion/MULTI and Asteion/MULTI multi-slice systems with highly integrated 34-channel detector system, both consisting of a total of 30,464 detector elements, were introduced. On the basis of such a structured detector matrix, a new image reconstruction procedure was used. This so called MUSCOT (Multislice Conebeam Tomography) procedure made the dream of an isotropic voxel in the…
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 use of state-of-the-art helical CT scanners allows for ultra fast examination of larger regions of the body. Due to the short examination time, optimum utilization of the intravenous contrast medium bolus is of extreme importance. The Sure Start function grants this in a very simple way.
Since the introduction of multi-slice computerized tomography (MS-CT), several authors have reported an increased exposure to radiation when using the manufacturer-specific protocols compared with the previous technique of single-slice computerized tomography (SS-CT). On the basis of comprehensive dose measurements conducted on a phantom, a study by S. M. Giacomuzzi et al reported that the mean…
The past several years, interventions using ultrasound for real-time image monitoring in diagnostic and therapeutic procedures have increasingly been integrated into the daily clinical routine. Limitations due to image-distorting physical effects, such as the total reflection at the soft tissue/lung boundary, are associated with the use of ultrasound. CT fluoroscopy on the other hand enables…
The Netherlands - September '00 - A good example of one of the discussions was the general issue of dose reduction. All participants agreed that it would be a challenge to be able to realise this, although this should definitely not interfere with the image quality. An interesting challenge for the users as well as the manufacturers! Many interesting topics were presented during the seminar, of…
Case 1 50-year-old male with a colorectal cancer. Greyscale imaging clearly shows the lesion, as an echogenic 3 cm mass (Fig.l a), which must be considered as suspicious for a metastasis from his colorectal cancer but benefit of the doubt must be given. Colour Doppler (Fig. 1b) is not helpful. At 33 seconds after SonoVue injection (early sinusoidal phase), Vascular Recognition Imaging (VRI)…
Image quality has been the most important criterion in CT scanner development for both radiologists and manufacturers, due to the diagnostic value of these systems. Recently, considerable concern has been expressed about the radiation dose to patients from CT examinations because: - CT delivers a higher dose than conventional film-screen examinations - Technological advances in CT have…
