In obstetric imaging, the fetal transverse cerebellar diameter (TCD) is often measured as an additional fetal biometric parameter. It is measured as the maximal diameter between the cerebellar hemispheres on an axial scan. The value of the transverse cerebellar diameter in mm's is considered roughly equivalent to the "gestational age in weeks" (particularly between the 14-20 weeks of gestation). The TCD is not thought to be significantly altered by the presence of IUGR ³.
