简要总结
This study aims to leverage structural, functional, and metabolic magnetic resonance imaging (MRI) of the brain to identify imaging features that correlate with clinical parameters. It is hypothesized that individuals with metabolic diseases exhibit distinct functional and structural brain differences compared to healthy controls. These differences may evolve over time due to changes in whole-body metabolism or body weight, influenced by factors such as the natural progression of the disease or therapeutic interventions. Additionally, potential brain changes may correlate with body composition metrics, such as the fat content of specific body compartments.
This is a prospective, single-center study conducted at Ulm University Hospital, designed to track the clinical and imaging histories of patients with metabolic diseases and compare them to healthy individuals. Eligible participants include adults (aged 18 and older) capable of providing informed consent. Recruitment will occur through routine clinical care or existing research studies. To provide a comprehensive understanding, the study will include both cross-sectional analyses and longitudinal follow-up of participants, integrating repeated assessments during routine medical visits.

Metabolic differences in the brain between patients with metabolic diseases and healthy controls
时间窗: cross-sectional and up to 5 years, depending on regular visits as part of routine patient care that, however, are not part of this scientific project.
Comparison of brain metabolic magnetic resonance imaging (Chemical Exchange Saturation Transfer (CEST)", MR-spectroscopy) between patients with metabolic diseases and healthy controls give insights into metabolic features in patients with metabolic diseases
Body Composition derived from magnetic resonance imaging
时间窗: cross-sectional and up to 5 years, depending on regular visits as part of routine patient care that, however, are not part of this scientific project.
Magnetic resonance imaging (DIXON sequence or fat-water imaging to determine the "Proton Density Fat Fraction" (PDFF)) will be used to determine the fat content in the different compartments of the whole body.
