Title:  
Brain Morphometry Based Developmental RetardationQuantification in Neonatal MRI

    Quantification of brain development retardation is important for diagnosing neonatal cerebral disorders. This study proposes a computer-aided method for estimating brain growth age based on brain morphometry change using T2-weighted MR images.The brain morphometry is characterized using anatomical predetermined landmarks. The estimation system is trained by using a learning dataset.It first applies principal component analysis (PCA)to a set of distances between all combinations of landmarks, and then derive a regression model whose dependent variable is revised age, and independent variables are PC scores.To estimate the brain age of a new subject, it obtains the feature vector as well as the learning procedure, transfers into PC scores using eigenvectors, and then estimates the brain age using the trained regression model.The proposed method was applied to 15 neonates (revised age was 33.7±40.7 days) with normal development and 4 neonates with abnormal development. The error for normalneonates are 15.5±11.8 days in training data and 46.3±37.2 in evaluation data, and the estimated brain age of abnormalsubject was different from their real age.It shows that the method could differentiate the brain growth age between normal and abnormal growing. The most advantage of this method is that it can be easily installed in clinical routine work because it only requires some landmarks.
