The left ventricular ejection fraction (EF) obtained by first pass radionuclide angiocardiography was compared with that determined by contrast angiocardiography in 49 patients. In 35 of the patients a comparison with the EF obtained by M-mode echoca

Purpose: To elucidate whether emphysematous lesions and other high‐resolution computed tomography (HRCT) findings considered associated with smoking are part of a progressive process, and to measure the extent to which similar changes are found in

The aim of this study was to investigate whether spiral CT is superior to high-resolution computed tomography (HRCT) in evaluating the radiological morphology of emphysema, and whether the combination of both CT techniques improves the evaluation in

The stimulable phosphor plate technique has revolutionised radiology with portable equipment. The image quality permits diagnosis under difficult control conditions (ICUs). In order to achieve a signal-to-noise ratio, and therefore a contrast resolut
