BACKGROUND Thoracic ultrasound-guided pleural procedures are associated with fewer adverse events than 'blind' procedures for patients with pleural effusion. Ultrasound is increasingly practised by respiratory physicians but there has been no prospective assessment of its safety and diagnostic accuracy when delivered by respiratory physicians. METHODS The activity level, safety and diagnostic a...
Accurate tool tracking is a crucial task that directly affects the safety and effectiveness of many interventional medical procedures. Compared to CT and MRI, ultrasound-based tool tracking has many advantages, including low cost, safety, mobility and ease of use. However, surgical tools are poorly visualized in conventional ultrasound images, thus preventing effective tool tracking and guidanc...
Ultrasound guidance has raised regional anaesthesia from an art relying on chiefly morphometric data to a science governed by reproducible and predictable methods. Besides the large number of scientific publications in the field of ultrasound and regional anaesthesia, there are still open questions regarding safety issues. In this issue of Anaesthesia, Sermeus et al. [1] present their findings ...
Ultrasound (US) imaging, due to its capabilities of real-time portability, low cost and favorable safety, is frequently used as a diagnostic modality for the visualization different diseases.
Ultrasound medical imaging is widely used nowadays in clinical application due to its intuitive, convenient, safety, non-invasive, and low cost. However, ultrasound image formation always comes with speckle-noise which will greatly reduce the image quality, and makes the identification and analysis of image detail become more challenging. Hence, we present an extended robust diffusion algorithm...
With ever increasing use of imaging as a diagnostic tool in medicine, medical schools are being urged to further integrate imaging into their curricula. Ultrasound is one such way of doing so-enabling students to bridge the gap between form and function, medical school and clinical practice. As a non-invasive imaging technique, with low risk when compared to other methods of imaging, ultrasound...
The third part of the European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) Guidelines on Interventional Ultrasound assesses the evidence for ultrasound-guided and assisted interventions in abdominal treatment procedures. Recommendations for clinical practice are presented covering indications, contraindications, safety and efficacy of the broad variety of these techn...
Radiofrequency (RF) and intense focused ultrasound (IFUS) are increasingly used to address skin laxity of the face and neck. Both nonablative RF and ultrasound create a heat-induced tissue response that leads to collagen remodeling and other ultrastructural changes. Although these treatments are not meant to replace surgical procedures, patient satisfaction in the majority of studies has been c...
Background The ExAblate system is a non-invasive thermal ablation device that has been used for the ablation of tissue. This system combines a focused ultrasound surgery delivery system and a conventional diagnostic 1.5 T MRI scanner (MRgFUS/MR guided focused ultrasound surgery). Starting from 2009 up to 2012 our Institute participated in the clinical randomized multi-site study to evaluate saf...
Use of ultrasound introduced as part of intensive care therapy makes viable bedside invasive procedures and diagnosis. Due to portability, combined with team training, its use guarantees less complications related to insertion, as well as patients' safety. It also reduces severe conditions related to the catheter, such as pneumothorax among others. Probably, in a near future, as purchase of ult...
