Symposium: Innovations in medical imaging
The Forum Medizintechnik-Pharma - an association that provides a recognised contribution to the development of the co-operative environment in medicine, technology and pharmaceuticals, met for a symposium in Germany this July.
The 5th World Conference on Breast Cancer
"Come and experience the great Canadian Prairie Hospitality!" say the organisers of the 5th World Conference on Breast Cancer (WCBC), to be held in June next year in Winnipeg, Manitoba - the "cultural cradle of the nation, gateway to the Canadian west, and a meeting place for over 6,000 years," the WCBC Foundation points out.
Furore over increased balloon angioplasty units
A decision by Ab Klink, Minister of Public Health, Wellbeing and Sports, to increase the number of balloon angioplasty facilities in hospitals to 30, has prompted the NVVC - the Dutch cardiologists association - to express concern that there will be too many centres and too few patients, and specialists will not be able to maintain the level of skills for this procedure.
CTA benefits coronary artery bypass graft patients
Cardiac CT angiography (CTA) performed after coronary artery bypass grafting surgery can reveal a high prevalence of unsuspected cardiac and significant non-cardiac findings that might otherwise be overlooked, according to a study by researchers at the University of Maryland Medical Centre, Baltimore ('Cardiac CT Angiography after Coronary Bypass Surgery: Prevalence of Incidental Findings', Pub:…
New Technology Academy opened in Germany
Hitachi Medical Systems has opened its European Technology Academy in Dusseldorf
Advanced Dynamic Flow (ADF)
Ultrasound scanning with CCDS is an established technique in shunt diagnostics and allows non-invasive assessment of vascular flow. Stenosing changes to walls of vessels used as a dialysis shunt should be detected as early as possible to avoid occlusion by a thrombus. High occlusion rates with volume flow reduced by up to 45% in one year demand ultrasound screening. The risk of haemodynamically…
Mammography Screening in Germany
Despite efforts in recent years to reduce the number of deaths caused by breast cancer it is still the most common cancer occurring in women. Approx. 47,500 new cases of the disease appear in Germany per year, a situation comparable with other European countries and with the USA. In 2004 alone, 17,592 women died from the sequela of a breast carcinoma (Federal Statistics Office statistics on…
When B Mode has an Image Problem
Ever heard this from a patient? 'Wouldn't it be great if it was in colour.' It's true; B mode lacks the glamour of Doppler. We're guilty of it ourselves, we love Doppler. How frequently do we hear 'did you put colour on that'? When was the last time you asked 'how much temporal smoothing did you use'? And yet every time I watch others scan I witness Sonographers scanning from various angles,…
Fresh Blood Imaging
In recent years MR angiography techniques have steadily created new possibilities in patient studies. The lack of radiation exposure and the fact that these new techniques are non-invasive, or at most minimally invasive, are just two of the obvious benefits. And in particular, within the last few years contrast-enhanced MR angiography has become an ever more preferred tool. This requires…
Carotid Plaque Imaging
Ischaemic stroke accounts for 80-85% of all cerebrovascular accidents and causes considerable morbidity and mortality, thereby placing a significant burden on western societies. In the UK alone, stroke costs amount to 10.4 billion EUR annually. These events commonly are a consequence of systemic atherosclerotic disease and with the internal carotid arteries supplying 75% of cerebral blood flow,…
Heart-Rate Adaptive CT Image Reconstruction
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…
Cardiac MSCT Study Assessment with Sure Plaque-Software
Ongoing refinement of modern helical multi-slice CT (MSCT) scanners offers the opportunity for very high temporal and spatial resolution thin-slice data set acquisition. The reconstruction techniques offered (multisegment reconstruction) result in improved temporal resolution down to 40-200 ms and thus also reducing motion artifacts. The SURECardio software package makes possible optimum studies…
Monitoring of Coronary Stenting
Coronary stenting is the most common way of treating symptomatic ischaemic cardiopathy and stenosis of venous bypasses. Restenosis actually occurs in 30% of patients treated with non-medicated stents while "drug eluting" stents have reduced the incidence of restenosis by approximately a quarter and have proved particularly effective in diabetic patients and in the treatment of lesions…
Radiation Treatment Planning
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…
Smooth workflow, excellent diagnostics and patient-friendly handling
With 715 beds, the University Hospital Maastricht is one of the leading hospitals in the Netherlands. The modern building offers 22 operating theatres and in 2005 24,362 patients were admitted. Due to rotating staff systems and multidisciplinary responsibilities in diagnostic imaging departments in large hospitals like the University Hospital Maastricht, the workflow has to be as easy as possible…
Clinical Experience with a Superconducting MRI Scanner
Following the installation of a 0.5-T superconducting magnetic resonance imaging (MRI) system at our hospital in 1987, we have been performing a large number of examinations as a key regional hospital serving the city of Muroran, Hokkaido, and surrounding areas. However, compared with more recently developed MRI systems, 0.5-T systems tend to have poorer image quality and a restricted range of…
Sonographic Indications of Fetal Chromosome Abnormalities
"Genetic ultrasound" is a refined technique in prenatal diagnostics. It aims to estimate as accurately as possible and non-invasively, the individual risk of a fetal chromosome abnormality. In conventional prenatal sonography (malformation screening) conspicuous fetal malformations are searched for selectively; naturally chromosomal anomalies of the fetus cannot be detected in this…
Tissue Doppler Imaging
Tissue Doppler Imaging (TDI) is an emergingnon-invasive ultrasound technique that makes it possible to measure velocities at any point of the ventricular wall during the cardiac cycle. Over the last ten years, TDI has been proposed as a feasible and useful imaging tool that provides information on regional wall motion dynamics.
