Contrast-enhanced computed tomography angiograms (CTAs) are widely used in cardiovascular imaging to obtain a non-invasive view of arterial structures. However, contrast agents are associated with complications at the injection site as well as renal toxicity leading to contrast-induced nephropathy (CIN) and renal failure. We hypothesised that the raw data acquired from a non-contrast CT contains sufficient information to differentiate blood and other soft tissue components. We utilised deep…

Contrast-enhanced to noncontrast CT transformation via an adjacency content-transfer-based deep subtraction residual neural network

A deep subtraction residual network based on adjacency content transfer is proposed to reconstruct noncontrast CT from contrast CT and maintain image quality comparable to that of a CT scan originally acquired without contrast.

Pseudo-Label Guided Multi-Contrast Generalization for Non-Contrast Organ-Aware Segmentation

A novel unsupervised approach that leverages pairwise contrast-enhanced CT (CECT) context to compute non-contrast segmentation without ground-truth label and further augment the intensity correlations in “organ-specific” settings and increase the sensitivity to organ-aware boundary.

CyTran: Cycle-Consistent Transformers for Non-Contrast to Contrast CT Translation

A novel approach to translate unpaired contrast computed tomography scans to non-contrast CT scans and the other way around, based on cycle-consistent generative adversarial convolutional transformers, for short, CyTran, which outperforms all competing methods.

Attention-Guided Supervised Contrastive Learning for Semantic Segmentation

This paper proposes an attention-guided supervised contrastive learning approach to highlight a single semantic object every time as the target, and proposes a novel two-stage training strategy to achieve such attention.



A Deep Learning Approach to Automate High-Resolution Blood Vessel Reconstruction on Computerized Tomography Images With or Without the Use of Contrast Agent

A modified U-Net architecture with attention-gating is implemented to establish a high-throughput and automated segmentation pipeline of pathological blood vessels in CT images acquired with or without the use of a contrast agent to reconstruct vascular structures from a computed tomography angiogram.

Medical Image Synthesis with Context-Aware Generative Adversarial Networks

A fully convolutional network is trained to generate CT given the MR image to better model the nonlinear mapping from MRI to CT and produce more realistic images, and an image-gradient-difference based loss function is proposed to alleviate the blurriness of the generated CT.

Coronary CT angiography: current status and continuing challenges.

The aim of this review is to present an overview of the role of coronary CT angiography on cardiac imaging, with focus on coronary artery disease in terms of the diagnostic and prognostic value of coronaryCT angiographic.

Low-Dose CT Image Denoising Using a Generative Adversarial Network With Wasserstein Distance and Perceptual Loss

This paper introduces a new CT image denoising method based on the generative adversarial network (GAN) with Wasserstein distance and perceptual similarity that is capable of not only reducing the image noise level but also trying to keep the critical information at the same time.

Simultaneous Super-Resolution and Cross-Modality Synthesis of 3D Medical Images Using Weakly-Supervised Joint Convolutional Sparse Coding

This paper proposes the weakly-supervised joint convolutional sparse coding to simultaneously solve the problems of super-resolution (SR) and cross-modality image synthesis and shows that the proposed method outperforms state-of-the-art techniques on both SR reconstruction and simultaneous SR and cross/modality synthesis.

A generative adversarial network (GAN) inspired approach for fast simulation of patho-realistic ultrasound images with a visual Turing test indicating an equivocal confusion in discriminating simulated from real is proposed.

Attenuation Correction Synthesis for Hybrid PET-MR Scanners: Application to Brain Studies

The aim of the proposed work is to improve attenuation correction for PET/MR scanners by generating synthetic CTs and attenuation maps through a multi-atlas information propagation scheme, locally matching the MRI-derived patient's morphology to a database of MRI/CT pairs, using a local image similarity measure.

Magnetic Resonance Image Example-Based Contrast Synthesis

This paper introduces an image restoration technique that recovers images with both the desired tissue contrast and a normalized intensity profile using patches in the acquired images and an atlas containing patches of the acquired and desired tissue contrasts.
