Why Some 3D/4D Scans Come Back “Non-Diagnostic”
A “non-diagnostic” result usually means the session focuses on bonding, comfort, and visual clarity rather than clinical interpretation.

Fetal position, placenta location, maternal body type, and even the amount of amniotic fluid can influence how clearly the baby’s face and features appear. The ultrasound technician may also need time for the probe to find the best angle, which means not every attempt produces the same level of detail. When the goal is keepsake imaging, the approach remains supportive and low-pressure, even if some images end up less crisp.
