Design for user efficiency in a dedicated ICU viewing station.

The intensive care unit (ICU) is one application where significant benefit is expected from the use of digital technology in the acquisition, management and presentation of images. However, the potential benefits should not be outweighed by disadvantages of current digital technology. One of the bottlenecks is the efficiency of image viewing using a workstation, especially if this viewing station is implemented using affordable commonly available hardware. In this paper we describe the design concepts of a relatively low-cost but efficient viewing station for chest images, and discuss clinical experience with this system at an ICU ward. The user interface has been optimized towards the specific patterns of ICU image viewing. By anticipating user requests and preparing images during idle times of the computer, the mean image access time could be reduced by a factor of 4, while most images could be presented instantaneously. Information from the hospital information system (HIS) is exploited in the user interface, and a simplified PAC-HIS coupling has been implemented for the simultaneous presentation of images and reports.

Role of magnetic resonance imaging in coronary heart disease.

Coronary heart disease (CHD) is the number one cause of morbidity and mortality in the developed countries. CHD involves a very broad clinical spectrum, ranging from stable angina pectoris to sudden cardiac death. Despite a huge improvement in treatment in the last 3 decades, significantly reducing the death rate, the prevalence of CHD will increase in the coming years due to an improved survival after a first acute myocardial infarction and due to an overall increased longevity, fueled by an epidemic of type-2 diabetes and obesity. This increased prevalence of cardiovascular disease will greatly impact the cost of health care. Moreover, new but often expensive imaging technologies are appealing for more accurate clinical and preclinical detection of CHD. Among these techniques, magnetic resonance imaging (MRI) is certainly one of the most promising. In this review we would like to highlight its potential in diagnosing CHD, against the background of a steadily increasing cost in health care and the need to choose the most cost-effective technique.

Magnetic resonance imaging in the evaluation of the pericardium. A pictorial essay.

Magnetic resonance (MR) is an ideal technique for the evaluation of the pericardium since it enables the combination of high resolution anatomical images of the pericardial layers with functional information concerning the impact of pathology on diastolic heart function and cardiac filling in particular. In comparison with echocardiography, which remains the first choice technique for the study of the pericardium, MR provides larger fields of view allowing the visualisation of the entire chest, higher spatial and contrast resolution and greater reproducibility. The technique becomes particularly useful when ultrasound imaging does not provide adequate diagnostic information or requires further characterisation; ''non-echoic'' patients, loculated pericardial effusions, focal thickening of the layers and pericardial masses are usually better assessed with MR. The method also provides valuable diagnostic information for establishing the diagnosis of constrictive pericarditis and to differentiate this condition from restrictive cardiomyopathy. The aim of this paper is to present the role of MR imaging in the assessment of a patient with suspected pericardial disease, and discuss the MR technique, anatomy and the main pathological conditions.
