How to misuse echo contrast
BACKGROUND Primary intracardiac tumours are rare, there are however several entities that can mimic tumours. Contrast echocardiography has been suggested to aid the differentiation of various suspected masses. We present a case where transthoracic echocardiography completely misdiagnosed a left atrial mass, partly due to use of echo contrast. CASE PRESENTATION An 80 year-old woman was referre...

Die meeste van ons leer tydens ons opleiding wat die werking en newe-effekte van m edikam ente is, maar baie min van ons word geleer hoe om m edikamente te misbruik. Dit lyk egter of dit ’n kuns is wat verskillende lede van die mediese en verpleegberoep asook die algemene publiek deur herhaalde bantering verkry. Die doel van die referaat is om voorbeelde te gee van enkele maniere waarop m edika...

متن کاملHow to Use and Misuse Image Assessment Algorithms
Natural images are meaningful to humans and used for a variety of tasks. The specific task to be performed dictates the assessment of an image’s suitability to the task. This work considers image assessment (IA) as a task-specific evaluation and examines the performance of a variety of objective IA algorithms for three different assessment tasks: fidelity assessment, quality assessment, and uti...
متن کاملHow to correct susceptibility distortions in spin-echo echo-planar images: application to diffusion tensor imaging.
Diffusion tensor imaging is often performed by acquiring a series of diffusion-weighted spin-echo echo-planar images with different direction diffusion gradients. A problem of echo-planar images is the geometrical distortions that obtain near junctions between tissues of differing magnetic susceptibility. This results in distorted diffusion-tensor maps. To resolve this we suggest acquiring two ...
