Background: Avulsion injuries of the pelvis and hip region are typical injuries in adolescent athletes but can be found in adults as well. Typical sites for avulsion injuries include the origin/insertion of tendons and ligaments. Among adolescents, the not yet ossified apophysis is also frequently involved.

- The study compares two cardiac MRI methods for detecting myocardial edema in patients with acute myocardial infarction (MI).
- Results show both methods exhibit high sensitivity for edema detection, but may underestimate edema in certain cases.
- Key findings include high performance metrics, with Tprep SSFP and dcFSE mapping demonstrating strong accuracy and reliable diagnostic capabilities.
Background: We report a case of hantavirus-induced myocarditis in a young adult. Hantavirus showed a rapid increase of infections in the year 2017. Only scarce data is available about potential myocardial involvement in hantavirus infections.

Thus, we determined the feasibility of cardiac magnetic resonance-based 2D global strain analysis using feature tracking and its association with cardiovascular risk factors in a sample from the general population.
Materials And Methods: Subjects without a history of cardiocerebrovascular disease were enrolled in a substudy of the population-based KORA (Cooperative Health Research in the Region of Augsburg) cohort.
Background: To evaluate the benefits of arterial phase imaging and parenchymal blood volume (PBV) maps acquired by C-arm computed tomography during TACE procedure in comparison to cross-sectional imaging (CSI) using CT or MRI.
Methods: From January 2014 to December 2016, a total of 29 patients with HCC stage A or B (mean age 65 years; range 47 to 81 years, 86% male) were included in this study. These patients were referred to our department for TACE treatment and received peri-interventional C-arm CT.
Background: Long-term intensive training induces physiological, morphological, and functional adaption of the athlete's heart.
Purpose: To evaluate the development of athlete's heart during a mid-term follow-up of competitive athletes using cardiac magnetic resonance (CMR).
Material And Methods: Eighteen competitive long-distance runners and triathletes (age 43 ± 13 years, 3 women) were prospectively examined in a longitudinal follow-up study 5.
Aims: To characterize changes in the myocardium in subjects with prediabetes, diabetes, and healthy controls with preserved left ventricular ejection fraction (LVEF) by using cardiac magnetic resonance imaging (CMR) in a sample from the general population.
Methods And Results: Subjects without history of cardiovascular disease and preserved LVEF but established diabetes, prediabetes, and controls from a population-based cohort underwent contrast-enhanced CMR. Obtained parameters included left ventricular (LV) function and morphology, late gadolinium enhancement as well as T1-mapping and derivation of extracellular volume fraction (ECV) by modified Look-Locker inversion recovery for diffuse fibrosis in a subset of patients.
Using cardiac magnetic resonance, we tested whether a single-breath-hold approach to cardiac functional evaluation was equivalent to the established multiple-breath-hold method. We examined 39 healthy volunteers (mean age, 31.9 ± 11.

The aim of the present study was to assess the anatomic distribution as well as the morphologic and histologic appearance of cardiac metastases from malignant melanoma.
Methods: Twenty five patients with known metastasized melanoma and with incidental finding of cardiac metastases during routine staging CT were retrospectively included in this study.
Article Synopsis
- - The study aimed to compare the left ventricular global function index (LVGFI) and late gadolinium enhancement (LGE) in patients with unrecognized myocardial infarction (UMI), recognized myocardial infarction (RMI), and those without myocardial infarction (MI).
- - In a review of 235 patients undergoing cardiac MRI, it was found that RMI patients had lower LVGFI values and more extensive LGE compared to UMI patients, indicating that RMI cases had a larger infarction scar size.
- - The conclusion highlighted that while LGE is useful for assessing infarction size, LVGFI does not effectively differentiate between patients with and without past MI due to overlapping values, explaining its limited use
Subclinical Disease Burden as Assessed by Whole-Body MRI in Subjects With Prediabetes, Subjects With Diabetes, and Normal Control Subjects From the General Population: The KORA-MRI Study.
Diabetes
January 2017
Article Synopsis
- Early disease manifestations in prediabetes are not well understood, prompting a study to assess metabolic and cardiovascular issues in individuals with prediabetes.
- The research involved 400 subjects, 103 of whom had prediabetes, and utilized MRI to evaluate changes in brain and heart health, revealing that individuals with prediabetes had a higher risk of carotid plaque and cardiac dysfunction compared to healthy controls.
- Findings indicate that people with prediabetes exhibit early, subclinical signs of disease, including changes in blood vessels, heart function, and body fat distribution, indicating the need for early intervention.
Background: To determine morphological and functional cardiovascular magnetic resonance (CMR) patterns in histopathologically confirmed myocardial involvement in patients with systemic sclerosis (SSc).
Methods: Twenty patients (6 females; mean age 41 ± 11 years) with histopathologically proven cardiac involvement in SSc in the years 2008-2016 were retrospectively evaluated. Morphological, functional and late gadolinium enhancement (LGE) images were acquired in standard angulations at 1.
Purpose: To introduce a dual-contrast fast spin-echo (dcFSE) sequence for signal decay mapping of myocardial edema.
Materials And Methods: After consultation with the Institutional Review Board, 22 acute myocardial infarction (MI) patients were examined with magnetic resonance imaging (MRI) at 1.5T 2 days after revascularization.
The purpose of the present study was to evaluate the potential of multimodal MR imaging including mean diffusivity (MD), fractional anisotropy (FA), relaxation rates R2 and R2* to detect disease specific alterations in Parkinson's Disease (PD). We enrolled 82 PD patients (PD-all) with varying disease durations (≤5 years: PD≤5, n = 43; >5 years: PD>5, n = 39) and 38 matched healthy controls (HC), receiving diffusion tensor imaging as well as R2 and R2* relaxometry calculated from multi-echo T2*-weighted and dual-echo TSE imaging, respectively. ROIs were drawn to delineate caudate nucleus (CN), putamen (PU), globus pallidus (GP) and substantia nigra (SN) on the co-registered maps.
