Russian researchers conducted a study aimed to enhance the differential diagnosis of fetal growth restriction (FGR) and small-for-gestational-age (SGA) fetuses using functional diagnostic methods.
The developed formula, which includes fetal abdominal circumference (mm) (AC), right uterine artery pulsatility index (RUtA-PI) (percentile), and cerebro-placental ratio (CPR) (percentile), enabled the diagnosis of FGR with a sensitivity of 84% and a specificity of 82%. To differentiate between SGA and FGR, a second formula was created, incorporating AC (mm), uterine artery pulsatility index (UA PI) (percentile), and middle cerebral artery pulsatility index (MCA PI) (percentile). This formula allows for the diagnosis of SGA as distinct from FGR, with a sensitivity of 67% and specificity of 88%.
The developed formulas facilitate the diagnosis of FGR and SGA, enabling timely decision-making regarding pregnancy management strategies. This approach aims to reduce the incidence of iatrogenic interventions, neonatal morbidity, and mortality while improving the quality of medical care.
