Assessment of fetal Sylvian fissure operculization between 22 and 32 weeks: a subjective approach

Sylvian fissure operculization (SFO) is a dynamic process throughout gestation and is a reliable feature of fetal cortex gyration that is amenable to prenatal ultrasound examination. This study aimed to define a subjective and reproducible method for SFO assessment.
