[The echographic measurement of fetal transverse cerebellar diameter in the second pregnancy trimester--a "nonstandard" method for determining gestational age].
The study was carried out on 192 women with normally progressing pregnancies during the second trimester, in whom the gestational age was determined by 291 echographic measurements of the fetal anatomic parameters-the biparietal diameter, length of the femoral bone and the transverse cerebellar diameter. The coefficients of correlation between each of the indicated parameters and gestational age as high values of correlation--0.96, 0.98, 0.98 were established. A brief literary review is made on the problem for determination of gestational age by measurement of the transverse cerebellar diameter of the fetus. Making more precise some technical details of the method, the authors recommend it for routine usage in the clinical practice.
