Numerous studies report on serial scans over short
periods of time or infrequent scans over a long period
of time but there are no published accounts of frequent
serial scanning for a long term. Here, MPRAGE,
dual-echo-T2, FLAIR, DTI and
magnetization-transfer-weighted scans were acquired
weekly in a normal control for four years. White matter,
gray matter, cortical gray matter and CSF volumes were
calculated. This data will be useful to validate the use
of these sequences for tracking changes in signal
intensity and brain volumes over time in patient groups
with subtle neurological disorders and for treatment
response.
