Early imaging is key to the diagnosis of the many anomalies that are unique to multifetal gestations. The third slideshow of our ultrasound collection includes examples of these anomalies.

While several fetal anomalies can be diagnosed early in the pregnancy, second-trimester ultrasound can identify or exclude even more conditions. The second slideshow of our ultrasounds collection includes the second-trimester anomalies of the body and limbs that shouldn't be missed.

Ultrasound imaging is a key prenatal tool for revealing structural anomalies that may point to genetic conditions. This slideshow is Part 1 of our collection of ultrasound anomalies and includes first-trimester anomalies and second-trimester anomalies of the head and brain. Part 2 will discuss second-trimester anomalies of the body and limbs.
