Medical ultrasound
A contrast medium for medical ultrasonography is a formulation of encapsulated gaseous microbubbles to increase echogenicity of blood, discovered by Dr Raymond Gramiak in 1968 and named contrast-enhanced ultrasound. This contrast medical imaging modality is clinically used throughout the world, in particular for echocardiography in the United States and for ultrasound radiology in Europe and Asia.
Neuromuscular ultrasound
Neuromuscular ultrasound refers to a field in medicine in which ultrasound is used to diagnosis and guide treatment for people with neuromuscular diseases. Neuromuscular ultrasound is often combined with electrodiagnosis, and particularly nerve conduction studies and EMG, to improve the accuracy of diagnosis and add anatomic information to the functional information obtained with electrodiagnosis. It has been demonstrated that neuromuscular ultrasound adds value to the diagnosis of nerve disease in over 80% of cases.
