The aim of this review is to emphasize the role of fetal MR in the evaluation of the supratentorial space. The advantages of MRI compared to US are stressed in three fields of application: cerebral biometry, sulcation and cerebral parenchyma. In each field, normal data are displayed and MR applications with patterns of the main pathologies are briefly described.
This article gives an overview of sample size calculations for parallel group and cross-over studies with Normal data. Sample size derivation is given for trials where the objective is to demonstrate: superiority, equivalence, non-inferiority, bioequivalence and estimation to a given precision, for different types I and II errors. It is demonstrated how the different trial objectives influence the null and alternative hypotheses of the trials and how these hypotheses influence the calculations. Sample size tables for the different types of trials and worked examples are given.
