abstract = {The measurement of quantitative, tissue-specific MR
properties, e.g., water content, longitudinal relaxation
time (T1) and effective transverse relaxation time (T2*),
using quantitative MRI at a clinical field strength (1.5 T
to 3T) is a well-explored topic. However, none of the
commonly used standard brain atlases, such as MNI or JHU,
provide quantitative information. Within the framework of
quantitative MRI of the brain, this work reports on the
development of the first quantitative brain atlas for tissue
water content at 3T. A methodology to create this
quantitative atlas of in vivo brain water content based on
healthy volunteers is presented, and preliminary, practical
examples of its potential applications are also
shown.Established methods for the fast and reliable
measurement of the absolute water content were used to
achieve high precision and accuracy. Water content and T2*
were mapped based on two different methods: an
intermediate-TR, two-point method and a long-TR, single-scan
method. Twenty healthy subjects (age 25.3 ± 2.5 years) were
examined with these quantitative imaging protocols. The
images were normalised to MNI stereotactic coordinates, and
water content atlases of healthy volunteers were created for
each method and compared. Regions-of-interest were generated
with the help of a standard MNI template, and water content
values averaged across the ROIs were compared to water
content values from the literature.Finally, in order to
demonstrate the strength of quantitative MRI, water content
maps from patients with pathological changes in the brain
due to stroke, tumour (glioblastoma) and multiple sclerosis
were voxel-wise compared to the healthy brain.The water
content atlases were largely independent of the method used
to acquire the individual water maps. Global grey matter and
white matter water content values between the methods agreed
with each other to within 0.5 $\%.$ The feasibility of
detecting abnormal water content in the brains of patients
based on comparison to a healthy brain water content atlas
was demonstrated.In summary, the first quantitative water
content brain atlas in vivo has been developed and a
voxel-wise assessment of pathology-related changes in the
brain water content has been performed. These results
suggest that qMRI, in combination with a water content
atlas, allows for a quantitative interpretation of changes
due to disease and could be used for disease monitoring.},
