Left Ventricle Segmentation and Quantification with Attention-Enhanced Segmentation and Shape Correction

Published: 24 August 2019 Publication History

Abstract

Quantification of the left ventricle (LV) is significant for cardiac disease diagnosis and progression assessment. Methods for LV quantification include segmentation based and regression learning method. However, the regression learning method cannot provide visual inspection, while the segmentation performance is still unsatisfactory, resulting in a large quantification error.
In this paper, we present a novel neural network to segment the endocardium and epicardium from short-axis cardiac magnetic resonance sequences, and then the 11 cardiac clinical parameters were quantified. The proposed model leverages channel attention mechanism and shape correction autoencoder, to adaptively enhanced the feature maps of different receptive field and correct the prediction shape that is inconsistent with the priors, respectively.
When validated with CMR sequences of 30 patients, the proposed model got mean dice coefficients of 0.9387, 0.9585, 0.8593 and mean Hausdorff Distances of 3.3983mm, 3.7879mm, 4.7710mm for endocardium, epicardium, and myocardium, respectively, which outperforms the classical Unet, and the state-of-art ACNN [1]. When it comes to the 11 quantification cardiac parameters, the prediction errors are lower or comparable with the best methods.
