Background Three‐dimensional imaging of superficial fetal abnormalities is well established. We prospectively evaluated if a technique of sectional planar imaging could interrogate nonsurface fetal abnormalities without changing transducers or requiring postrendering software. Method Patients referred for perinatal consultation received traditional 2‐D scanning and simultaneous volume mode imaging. Fetal abnormalities were visualized with a sectional technique similar to ‘tomogram’ slices. No post image rendering manipulation was required. Twelve patients had correlative MRI scanning. Neonatal images were obtained when possible. Results Structural fetal abnormalities amenable to volume rendering were found in 192 of 600 referral patients. Of these, 49% (94/192) benefited from 3‐D planar imaging. Consistently improved counseling occurred with abdominal wall defect (11/11), cystic hygroma (8/8), neural tube defect (8/8), skeletal dysplasia (5/5), hydrops (5/5), ovarian mass (4/4), myoma (9/11), and fetal chest mass (2/3). Moderate image concordance was seen for nuchal thickness (4/8), renal dysgenesis (27/50), and placental mass or separation (7/12). Lowest concordance was seen for echogenic bowel (0/17), isolated SUA (0/9), and CPC (4/41). Conclusion Complex syndromes with superficial and deep architecture are accessible with a simple volume mode planar scanning technique. The additional information is immediately available and useful in counseling of these syndromes.
