PRFS thermometry is important
for guidance of thermal therapies. Here we show that the thermometry sequence
can be accelerated by the novel parallel imaging technique SMS-CAIPIRINHA and
we compare it to an unaccelerated sequence and a SENSE accelerated sequence.
Heating was applied by means of HIFU and LITT. A good agreement was seen
between temperature curves from SMS-CAIPIRINHA and those from the unaccelerated
sequence. Furthermore, the noise level was significantly lower compared to
temperature curves from the SENSE accelerated sequence.
