Abstract

Get outstanding guidance from the world's most trusted reference on OB/GYN ultrasound. Now brought to you by lead editor Dr. Mary Norton, Callen’s Ultrasonography in Obstetrics and Gynecology has been completely and exhaustively updated by a team of obstetric, gynecologic, and radiology experts to reflect the most recent advances in the field. It addresses the shift in today's practice to a collaborative effort among radiologists, perinatologists, and OB/GYNs, with new emphasis placed on genetics and clinical management. This must-have resource covers virtually all aspects of fetal, obstetric and gynecologic ultrasound — from the common to the rare — in one essential clinical reference, allowing you to practice with absolute confidence.

  • Highly templated, full-color format allows you to locate information more quickly.
  • Full-color medical illustrations present key anatomic details in a clear manner.
  • Thousands of digital-quality images depict the complete range of normal and abnormal imaging presentations.
  • Provides extensive updates of text and images, including the latest in imaging, Doppler techniques, genetic testing, and clinical management.
  • Brand new chapters provide up-to-date, comprehensive coverage of topics relevant to current practice:

-First Trimester Fetal Anatomy

-Obstetric Ultrasound and the Obese Patient

-Evaluation of Pelvic Pain in the Reproductive Age Patient

-Gynecologic Ultrasound in the Pediatric and Adolescent Patient

-Ultrasound and Magnetic Resonance Imaging in Urogynecology

-The Role of Ultrasound in Gynecologic Interventions

  • Highlights significant new genetic testing content, including correlation with ultrasound evaluation of the fetus.
  • Places increased emphasis on 3-dimensional imaging and correlative imaging with magnetic resonance (MR).
  • Features new practice guidelines for obstetric evaluation (including first trimester assessment) and gynecologic management (including evaluation of the endometrium and of ovarian masses).
  • Features new information about fetal imaging guidelines from the National Institute of Child Health and Human Development (NICHD).
  • Provides expanded discussion of fetal, obstetric, and gynecologic interventions with new emphasis on clinical use and application of ultrasound imaging.
  • Includes key and comprehensive reference data used for evaluation of fetal growth and other specialized measurements.
