This new edition not only describes how to obtain the required images but also gives practical guidelines on the interpretation of the findings. The suggestions in the text are a distillate of those used in the authors' own practice, and as such have grown from many years of working in teaching centres with high referral rates. The authors believe that those who follow the advice given, be they clinicians or technicians, will reassure the woman with a normal pregnancy. Management of women with an abnormal pregnancy commonly involves a team approach with ultrasonographers, obstetricians, paediatric surgeons, neonatologists and geneticists but the guidelines given should allow the ultrasonographer to talk to the women in an informative fashion before making arrangements for further referral. New material for this edition includes a new chapter on blood flow, new material on gynaecological conditions, a new colour plate section and new tables and appendices.
