PY - 2023 T2 - Timor's Ultrasonography of the Prenatal Brain, 4e AB - Prenatal diagnosis should be instituted accurately and early enough to achieve an excellent level of care of the obstetric patient. Ultrasonography, with its excellent resolution and image quality, makes it easier for health care providers to reach appropriate management decisions. Assessing whether the size of a structure is normal or abnormal may not always be feasible, but if doubt exists regarding its normalcy, it must be carefully and diligently pursued. In addition, several measurements, such as the biparietal diameter (BPD) and the head circumference (HC), can also be used to determine the gestational age of a fetus, especially during the first half of pregnancy. Correct estimation of gestational age is of paramount importance because adequate management of both low-and high-risk obstetric populations relies heavily on knowing the precise gestational age.
