**Preface**

Pregnancy is a unique period in a woman's life. The physiological changes that occur help the mother's body to adapt to this transitional period. Ultrasonography is the most used imaging exploration method in pregnancy. It has broad applicability in prenatal diagnosis, both regarding the detection of foetal malformations and the evolution of the pregnancy. The pathologies that can be associated with pregnancy can lead to maternal and foetal complications that require medical interventions in order to complete the pregnancy in good conditions. This volume includes studies on the diagnosis, evaluation and management of pathologies diagnosed during pregnancy. The information provided in these pages will be helpful for specialists in the field of obstetrics and gynaecology, potentially improving case management. The authors of the articles included in this Special Issue aimed to present their personal achievements or structured information related to specific essential topics in the form of reviews, and we thank them for their efforts. We also thank the reviewers for their suggestions and recommendations, which increased the quality of the manuscripts. Additionally, the Editorial Office of *Medicine* provided us with excellent support, which significantly eased the Guest Editors' job. This volume is the result of the combined efforts of all involved.
