Summary: The developed predictive model is able to identify patients with high risk of fibrosis in hypertrophic cardiomyopathy (HCM) through fusion of image and radiomic features, and screen out patients without fibrosis, avoiding unnecessary injection of contrast.

Summary: Parametric mapping is a pixel-wise mapping of magnetic relaxation parameters, which allows for quantification of myocardial tissue-specific magnetic relaxation. It has expanded the diagnostic potential of cardiac magnetic resonance and is important for the diagnosis of nonfocal diseases, longitudinal disease monitoring, and risk stratification.

Summary: Advances in cardiac imaging techniques have enabled non-invasive tissue characterization of the myocardium, providing valuable insights into specific disease processes. The diagnostic accuracy, incremental yield, and prognostic value of speckle tracking echocardiography, late gadolinium enhancement, and parametric mapping modules by cardiac magnetic resonance and cardiac computed tomography have been validated against tissue samples, offering relevant clinical information to cardiologists.

Summary: Infection with SARS-CoV-2, the virus that causes COVID, can lead to various cardiovascular complications. Cardiac imaging has become crucial in differentiating pulmonary and cardiovascular complications due to the non-specific symptoms and laboratory findings of COVID patients. This review summarizes the existing literature and major societal guidelines to provide an overview of the indications and utility of different cardiac imaging modalities for diagnosing cardiovascular complications of COVID.

Summary: This study used machine learning and radiomics features to build predictive models for predicting major adverse cardiovascular events in patients with left ventricular myocardial noncompaction (LVNC). The results showed that the machine learning models performed well and adding radiomics features offered incremental prognostic value over clinical factors alone.

Summary: Systemic sclerosis (SSc) is characterized by internal organ fibrosis, including the heart, leading to high morbidity and mortality. Cardiac magnetic resonance (CMR) can assess myocardial function and tissue characteristics in the same examination. The Lake Louise criteria (LLC) can be used to identify recent myocardial inflammation using CMR. Abnormal values include myocardial over skeletal muscle ratio, early gadolinium enhancement values, and epicardial/intramyocardial late gadolinium enhancement.

Summary: Adverse remodeling is a major characteristic of heart failure (HF) and can be reflected by either focal or diffuse myocardial fibrosis. This study investigated the association of (focal or diffuse) fibrosis with cardiac biomarkers and adverse events in HF patients by using immunohistochemistry or cardiac magnetic resonance imaging (CMR). The results suggest that cardiac biomarkers can reflect active remodeling in the non-infarcted myocardium of patients with focal myocardial scarring. Additionally, diffuse fibrosis may have a higher prognostic value regarding adverse outcomes in HF patients.

Summary: Cardiac magnetic resonance imaging (MRI) is commonly used for noninvasive assessment of cardiac structure and function, with 1.5 T traditionally being the preferred field strength. While 3 T systems have seen significant growth in the past decade, there are still challenges hindering their widespread clinical use for cardiac applications. Different clinical benefits exist for each field strength and there is no universal recommendation for the ideal field strength for cardiac MRI. The review discusses the physical differences between 1.5 and 3 T, their impact on various cardiac MRI applications, and provides solutions to overcome potential limitations.

Summary: The efficacy of an in-line non-rigid motion-compensated reconstruction (NRC) in an image-navigated high-resolution three-dimensional late gadolinium enhancement (LGE) sequence with Dixon water-fat separation was investigated in a clinical setting. The study found that NRC outperformed translational motion-compensated reconstructions (TC) in overall image quality, contrast ratios, and LGE quantification. The sharper depictions of LGE in NRC may lead to more accurate measurements.

Summary: This study examined the relationship between cardiovascular abnormalities and the severity of chronic kidney disease using cardiac magnetic resonance imaging. The results showed that myocardial strain, native T1, and T2 values progressively worsened with advancing chronic kidney disease stage.

Summary: This study proposes a method to obtain phase-resolved late gadolinium enhancement (LGE) images using cardiac magnetic resonance imaging. The method involves three steps and has been evaluated in phantom imaging, healthy subjects, and patients. The results demonstrate reliable imaging in the phantom and healthy subjects, while the imaging resolution and noise resilience in patients are lower compared to the reference technique. The proposed technique shows potential in integrating the advantages of phase-resolved cardiac magnetic resonance with LGE imaging, but further improvements are needed for clinical use.

Summary: Systemic sclerosis (SSc) is a systemic autoimmune disorder characterized by inflammation and fibrosis. Cardiac involvement is common in SSc but often asymptomatic for a long time, highlighting the importance of accurate and early detection. Cardiac magnetic resonance imaging (CMR) has emerged as a valuable tool for diagnosis and prognosis in SSc patients.

Summary: Cardiac magnetic resonance (CMR) imaging technology is considered the gold standard for evaluating myocardial function and viability in acute myocardial infarction (AMI). Various CMR techniques can specifically display and evaluate the pathophysiological changes in each stage of AMI. This article reviews the recent advances of CMR technology in AMI and prospects its future development directions.
