Lung Ultrasound
Ultrasound (US) has been excluded from assessment of lung pathology for many decades. In fact, the acoustic characteristics of thoracic structures make them unsuitable for morphological US imaging in most cases. Bone and air are notorious “enemies” of US as they prevent their penetration thus obscuring deeper structures. Lung ultrasound relies on interpretation of many different artifacts and p...
متن کاملAdvances in lung ultrasound
Ultrasound examination of the chest has advanced in recent decades. This imaging modality is currently used to diagnose several pathological conditions and provides qualitative and quantitative information. Acoustic barriers represented by the aerated lungs and the bony framework of the chest generate well-described sonographic artifacts that can be used as diagnostic aids. The normal pleural l...
متن کاملQuantitative ultrasound and bone health.
This review of quantitative ultrasound (QUS) and bone health uses the current literature to summarise the clinical and research effectiveness of QUS. QUS has been demonstrated to have the ability to predict fracture, particularly at the hip. However, the magnitude of prediction is fracture-site, measurement-site and device dependent. The correlations between dual X-ray absorptiometry (DXA) and ...
متن کاملUltrasound Detection of Lung Hepatization
Bedside ultrasound interrogation of the thorax can aide the clinician in determining the cause of the respiratory dysfunction. Often plain radiographs are not sufficient to differentiate pathology. We present a case in which bedside ultrasound defined the pathology without the need for further imaging.
متن کاملUltrasound Quantitative Evaluation of Human Eye Cataract
A technique to improve an eye cataract early detection and quantitative evaluation of maturity using ultrasound was investigated. A broadband coherent signal, backscattered from an eye lens tissue, was digitized, recorded and processed. A new parameter – lens quality was proposed for the human eye cataract quantitative evaluation. Lens quality reflects two phenomena of ultrasound interaction wi...
