  • Segmentation and analysis of brainstem in Alzheimer MR images using region based level set method

    BMT 2016 Conference in Basel, Switzerland

    Accurate segmentation of brain structures from MR images has been an open challenge mainly due to the absence of clear edges. Recent study on Alzheimer’s Disease (AD) have pointed towards brain stem to be the epicenter of the disease but few attempts have been made to decipher the effects of AD on brainstem structures. In this paper, an effort is made to segment brainstem and characterize it as a potential biomarker for detection of AD. A novel segmentation technique has been proposed to…

    Accurate segmentation of brain structures from MR images has been an open challenge mainly due to the absence of clear edges. Recent study on Alzheimer’s Disease (AD) have pointed towards brain stem to be the epicenter of the disease but few attempts have been made to decipher the effects of AD on brainstem structures. In this paper, an effort is made to segment brainstem and characterize it as a potential biomarker for detection of AD. A novel segmentation technique has been proposed to segment brainstem from the mid-sagittal view of the brain. The MR images which were used, are obtained from a public database containing 163 images from AD (CDR = 1) and non-AD (CDR = 0) classes. The MR images used for segmentation were preprocessed using skull-stripping and bilateral filtering. A distance regularized level-set evolution was implemented on the image to segment the brainstem structures. Along with improving the accuracy of segmentation, there has been an added focus on extracting features which could potentially help us classify AD from non-AD MR images. Features such as entropy, area and perimeter were processed using an SVM classifier and validated by a five-fold cross-validation. The brainstem was successfully segmented with an average accuracy of 96% (Pearson’s Correlation Coefficient), which is significantly higher than most standard techniques. The mean entropy, area and perimeter of the brainstems extracted from AD MR images were 8.8%, 8.3% and 9.6% lower than brainstems extracted from non-AD MR images, respectively. As this classification can lead to early detection of AD, this work could have clinical significance.
