Diagnostic Ultrasound Safety Review for Point‐of‐Care Ultrasound Practitioners

Medical Diagnostic Ultrasound

Diagnostic ultrasound in haemophilia.

Ultrasound examination has been recommended for the evaluation of acute haemorrhages into soft tissues or joints in haemophilic patients. We have reviewed the notes of all such patients admitted during one calendar year and find that in 47 separate admissions the ultrasound examination assisted management decisions on 27 occasions. The technique is described with an analysis of the ways in whic...

Diagnostic Accuracy of Acute Appendicitis by Ultrasound in Hospital Emergency

Background Acute appendicitis is the most common medical condition requiring immediate abdominal surgery.Medical ultrasound is a non-intrusive, non-expensive and available diagnostic method. In this study, the accuracy of ultrasound in diagnosis of acute appendicitis in hospital emergency was evaluated. Materials and Methods This retrospective cohort study was performed at Ahvaz Imam Khomeini h...

Bioeffects considerations for diagnostic ultrasound contrast agents.

Diagnostic ultrasound contrast agents have been developed for enhancing the echogenicity of blood and for delineating other structures of the body. Approved agents are suspensions of gas bodies (stabilized microbubbles), which have been designed for persistence in the circulation and strong echo return for imaging. The interaction of ultrasound pulses with these gas bodies is a form of acoustic...

Visual Servoing for Robot-assisted Diagnostic Ultrasound

A robot system for positioning an ultrasound probe has been developed [1]. Ultrasound visual servoing can be used to help ultrasound technicians position the ultrasound probe. The feasibility of visual servoing for motion in the plane of the ultrasound probe in one dimension has been addressed here. Tracking of the carotid artery for a long period of time has been demonstrated in real-time. Two...
