Summary: Accurate computing, analysis, and modeling of ventricles and myocardium are crucial for the diagnosis and treatment management of patients with myocardial infarction. This paper presents the selective results from a Multi-Sequence Cardiac MR Segmentation challenge, which provided a dataset of paired MS-CMR images for algorithm development and benchmarking. The results showed that the top-ranking algorithms could generate reliable and robust segmentation results, thanks to the inclusion of auxiliary sequences from MS-CMR images.

Summary: This study demonstrates the feasibility of cardiac MR thermometry at 0.55 T and characterizes its in vivo stability using state-of-the-art techniques. The cardiac MR thermometry protocol was successfully acquired in healthy volunteers and the stability of thermometry was evaluated. The results suggest that cardiac MR thermometry at low field is feasible and provide a basis for further research on MR-guided catheter ablations at low field.

Summary: 18F-FDG PET/MRI may be the preferred diagnostic method for Hodgkin lymphoma patients due to its combination of metabolic information from PET and excellent soft-tissue contrast from MRI, while avoiding radiation exposure from CT. However, longer examination times are a major issue, especially for children requiring anesthesia. Therefore, a targeted selection of suitable whole-body MRI sequences is important to optimize the PET/MRI workflow.

Summary: A fully automated computer-aided diagnosis system for the detection and segmentation of metastatic bone disease using whole-body multi-parametric MRI is proposed. The system outperformed state-of-the-art methodologies, achieving a detection sensitivity of 63% with an average of 6.44 false positives per image, and an average lesion Dice coefficient of 0.53.

Summary: This study evaluated the presence of abnormal MRI diffusion weighted imaging (DWI) foci following digital subtraction angiography (DSA) and compared the frequency between transradial arterial access (TRA) and transfemoral access (TFA) in cerebral angiography. The results showed that TRA was associated with a significantly higher incidence of DWI restriction foci compared to TFA. Although the number of clinically symptomatic events was minimal, further studies comparing TRA and TFA techniques are needed for clinical practice in cerebral angiography.

Summary: This study proposes a two-stage pipeline for detecting and synthesizing missing slices in cardiac MR acquisition. The proposed network can infer anatomically plausible missing slices and improve the accuracy of subsequent analyses on cardiac MRIs through synthesized image slices. Experimental results show that this method outperforms incomplete data in analysis.

Summary: In this study, a cascaded deep learning pipeline trained with augmentation by synthetically generated data was proposed to improve the accuracy and robustness of scar quantification in late gadolinium enhancement cardiac MRI. The results showed that the cascaded pipeline outperformed direct segmentation methods and the augmentation with synthetic data enhanced the accuracy of scar segmentation.

Summary: The study found that quantitative whole-body functional MRI examination can serve as an effective complement to imaging diagnosis based on morphology and provide further information on the tumor burden of patients with MM. ADC and FF showed significant differences in different MM infiltration patterns and correlations with various prognostic biomarkers.
