The objective of this study was to describe normal postpartum findings seen with fast whole-body magnetic resonance imaging of healthy, term neonates.
We prospectively analyzed whole-body 3.0-T magnetic resonance imaging of 53 normal neonates scanned within 72 hours of birth to assess for postpartum-related findings.
Increased T2 signal within the subcutaneous and fascial tissues was the most common finding. This pattern was seen in 73.5% of neonates, within 32% of the upper extremities and 62% of the lower extremities. Additional patterns of increased T2 signal were seen in the cervical region, joint spaces, groin, and axilla. Several of these patterns were more common in larger infants. No significant differences were seen between vaginal and cesarean deliveries.
The presence of fascial fluid as demonstrated with whole-body magnetic resonance imaging is considered a normal finding in postpartum neonates, likely related to the birthing process of labor and not an indication of underlying pathology.
