Comparison of Two Modalities: Ultrasound versus Computed Tomography

摘要: If one compares the diagnostic spectrum and efficacy of two competing imaging methods, a multitude objectives need to be assessed; these include degree invasiveness, ease performance, cost, associated noxious effects as well accuracy, sensitivity, specificity. While several items can addressed squarely unequivocally, others are more difficult discuss. There is copious literature on accuracy computed tomography (CT), including large autopsy series2, 5, 38, 39 also sufficient data concerning clinical comparison sonography CT, particularly intracerebral hemorrhage ventricular dilatation. However, fewer available ultrasonic clinicopathologic correlations, at this writing there no major series postmortem ultrasound- CT comparisons. Nevertheless, observations in permit general modalities. In course discussion, we will refer our own experiences.
