abstract = {Magnetic resonance imaging (MRI) yields important
information on the development and current status of many
different diseases. Whole-body MRI was accordingly made a
part of the multicenter, population-based NAKO Health Study.
The present analysis concerns the feasibility of the
baseline MRI examination and various aspects of quality
assurance over the period 2014-2019.32 252 participants in
the NAKO Health Study, aged 20 to 74, who had no
contraindication to MRI were invited to undergo scanning in
one of five MRI study centers across Germany. The whole-body
MRI scan took about one hour and consisted of sequences for
the visualization of structural and functional features of
the brain, musculoskeletal system, cardiovascular system,
and thoracoabdominal system. A comprehensive
quality-assurance assessment was carried out, with
evaluation of adverse events, the completeness of the MRI
protocols, the participants' subjective perceptions, and
image quality.31 578 participants $(97.9\%)$ were
successfully included in the MRI study. They reported a high
level of comfort and suffered no severe adverse events (mild
adverse events occurred in only four participants).
Depending on the imaging sequence, the image quality was
rated as excellent in $80.2\%$ to $96.8\%$ of cases. Quality
assessment with respect to structural features of the brain
revealed high consistency across study centers, as well as
with regard to age- and sex-based differences in brain
volume (men, 1203.81 ± 102.06 cm³; women, 1068.10 ± 86.69
cm³).Whole-body MRI was successfully implemented in the
NAKO baseline examination and was associated with high
patient comfort and very good image quality. The imaging
biomarkers of the brain confirmed previously observed
differences based on age and sex, underscoring the
feasibility of data pooling.},
