Infos

The use of neurovascular ultrasound is of increasing importance in neurological practice, both for radiologists and increasingly by neurologists themselves. Written by the world's most renowned expert, this book explains

• 
  
• ultrasound examination of a stroke patient
  
• scanning protocols
  
• interpretation of the results

Case examples (with a standard template presentation correlating presentation to waveform output) reinforce the book's practical nature.

Illustrated with photos of the tests, explanations, and with actual waveforms, images, and result interpretation, and enhanced with 'pearls' and 'avoiding pitfalls' features, it is a practical reference for those learning ultrasound as well as those using ultrasound in their practices.
