The book was written for radiologists who wished to achieve a better understanding of basic anatomy and pathology using high resolution ultrasound techniques. However, as a head and neck surgeon now into the field of diagnostic ultrasound including US fine needle aspiration, this book was exactly what I was looking for. It is clear, well marked and written, and clearly written for a practicing clinician. It does not delve at all into the physics and makes a practical assumption that there is some skill level by the operator prior to reading this book. It is also very well organized with two different tracks. The first is dividing the discussion by functional areas, i.e. thyroid, lymphatics, etc. Next it is written by anatomical areas, i.e. Levels 1-6, larynx, carotid, parotid, etc. If you are interested in getting into this field, you will need a bit of practice with this technology prior to reading the book, but once you do, it is immensely helpful.
