Measurement of key parameters is an essential part of interpreting ultrasound scans and differentiating normal anatomy from pathology. Resident radiologists and ultrasonographers often find it difficult to gain a good appreciation of such measurements. This book is a user-friendly handbook that can be used in a day-to-day practice. It is made up of a series of ultrasound images with accompanying explanatory line drawings together with all key measurements. Normal variants are given together with ranges for features that change during development. There is also a list of key references for each criterion. Features include: * Easy-to-use manual with important information quickly to hand while scanning * Comprehensive coverage of all modern ultrasound techniques * Ultrasound images and explanatory line drawings to clarify measurement criteria
