Sickle cell anaemia (SCA) is a genetic disorder
affecting haemoglobin. Previous studies suggest that the
iron content in some deep-brain regions is higher in
transfused SCA patients (TSCA) than in healthy controls
(HC). We hypothesised that iron content in those regions
is lower in non-transfused patients (NSCA) than in
controls as NSCA have low haematocrit. A pilot study (5
TSCA, 5 NSCA, 5 HC) showed that susceptibility values
were significantly lower in the globus pallidus of both
TSCA and NSCA than in HC, supporting our second
hypothesis. A larger study (20 NSCA, 18 HC) showed a
trend in this direction.
