Neural Network
- Abstract summary: This paper proposes a method for fully automatic semantic segmentation of epicardial adipose tissue from CT images using a deep neural network.
The proposed network uses a U-Net-based architecture with slice depth information embedded in the input image to segment a pericardium region of interest.
Cross-validation of the proposed method yields a Dice score of 0.86 on the CT scans of 20 patients.

- Abstract: Epicardial adipose tissue is a type of adipose tissue located between the
heart wall and a protective layer around the heart called the pericardium. The
volume and thickness of epicardial adipose tissue are linked to various
cardiovascular diseases. It is shown to be an independent cardiovascular
disease risk factor. Fully automatic and reliable measurements of epicardial
adipose tissue from CT scans could provide better disease risk assessment and
enable the processing of large CT image data sets for a systemic epicardial
adipose tissue study. This paper proposes a method for fully automatic semantic
segmentation of epicardial adipose tissue from CT images using a deep neural
network. The proposed network uses a U-Net-based architecture with slice depth
information embedded in the input image to segment a pericardium region of
interest, which is used to obtain an epicardial adipose tissue segmentation.
Image augmentation is used to increase model robustness. Cross-validation of
the proposed method yields a Dice score of 0.86 on the CT scans of 20 patients.

Key manifestation of coronary artery disease is development of fibroatheromatous plaque, the cap of which may rupture and lead to coronary artery blocking and heart attack.

Our FiAt-Net achieved high performance on a 3D IV OCT coronary image dataset, demonstrating its effectiveness in accurately detecting FA cap in IV OCT images.
