DIAGNOSTIC IMAGING: Obstetrics, Fetal Anomalies, and Maternal Complications Ultrasound, MRI, and Clinical Decision Frameworks from First Trimester to Delivery

Obstetric imaging is among the most consequential disciplines in diagnostic radiology. Every scan carries the weight of two patients, and every finding demands not just recognition but reasoning. This textbook was written to build both.Diagnostic Imaging: Obstetrics by Dr. Camille Anne Rousseau is a comprehensive, evidence-based clinical reference covering the full spectrum of obstetric ultrasound and fetal MRI from the first trimester through delivery. It is written for radiologists, maternal-fetal medicine specialists, obstetric sonographers, radiology residents and fellows, and any clinician whose practice requires a deep and clinically integrated understanding of obstetric imaging.The book is organized across eight sections. Section I establishes the imaging foundations with dedicated chapters on ultrasound physics and technique, fetal MRI indications and safety, and a trimester-by-trimester normal fetal anatomy reference. These opening chapters address the technical and physiological knowledge required before approaching any abnormal finding, and they represent content absent from all major competing obstetric imaging references.Section II covers first-trimester imaging in full, including normal gestational landmarks and failed pregnancy criteria, the complete anatomical spectrum of ectopic gestation, and a dedicated chapter on first-trimester screening covering nuchal translucency measurement, cell-free DNA, combined screening, and the genomic toolkit. Sections III through V address the fetal central nervous system, face and neck, chest and heart, abdomen, pelvis, and musculoskeletal system across ten chapters, covering every major structural anomaly with pathophysiology, multimodality imaging correlation, and postnatal outcome data.Section VI covers placenta, cord, multiple gestations, fetal growth, and fetal wellbeing across six chapters, including placenta accreta spectrum with surgical planning implications, vasa previa screening, twin-to-twin transfusion syndrome staging and laser treatment imaging, fetal growth restriction Doppler surveillance, and hydrops fetalis aetiological work-up. Section VII addresses chromosomal aneuploidies, fetal syndromes, and congenital infections including updated SMFM guidance on soft markers, the complete genomic testing toolkit from karyotype through whole exome sequencing, and the imaging signatures of CMV, parvovirus, Zika, and other congenital infections.Section VIII is the book's distinguishing section, covering maternal uterine anomalies and fibroids in pregnancy, cervical assessment and preterm birth imaging, adnexal masses and the acute obstetric abdomen, postpartum imaging, structured reporting with complete templates for every examination type, and fetal intervention imaging across all currently practiced procedures.Every chapter follows a consistent architecture covering pathophysiology, systematic imaging approach, multimodality correlation, variant and diagnostic pitfalls, postnatal correlation, and clinical management implications. Each chapter includes a clinical pearl, an evidence-based medicine box referencing named trials and current society guidelines, and a clinical decision algorithm.Topics covered include placenta accreta spectrum imaging and surgical planning, TTTS Quintero staging and post-laser surveillance, fetal growth restriction Doppler thresholds, congenital CMV fetal MRI findings, skeletal dysplasia systematic evaluation, conotruncal cardiac defect screening, and structured reporting templates for anatomy survey, fetal echocardiography, and fetal MRI.This textbook is designed to serve as both a learning resource for trainees and a long-term clinical reference for practicing specialists in obstetric imaging and maternal-fetal medicine.
