What stroke protocol is your speech therapist going to create to treat aphasia with this?

The brain processes read and heard language differently. This is the
key and new finding of a study at the University Department of Radiology
and Nuclear Medicine at the MedUni Vienna, unveiled on the eve of the
European Radiology Congress in Vienna (6 to 10 March). The researchers
have been able to determine the affected areas of the brain using speech
processing tests with the aid of functional magnetic resonance
tomography (fMRT).
The results of the study, published in the highly respected magazine
“Frontiers in Human Neuroscience”, offer the field of radiology new
opportunities for the pre-operative determination of areas that need to
be protected during neurosurgical procedures – for example the removal
of brain tumours – in order to maintain certain abilities. With regard
to the speech processing parts of the brain in particular, individual
mapping is especially important since individuals differ in terms of the
location of their speech processing centres. “This also gives
radiologists a tool with which they can decide whether it makes more
sense during testing to present the words in visual or audible form,"
says Kathrin Kolindorfer who, together with Veronika Schöpf (both from
the University Department of Radiology and Nuclear Medicine at the
MedUni Vienna), headed up the study.
Personalised planning of radiological investigations
For
the test design, the healthy test subjects were played simple nouns via
headphones or shown them on a screen. They then had to form matching
verbs from them. Says Kolindorfer: “Depending on whether the words were
heard or seen, the neurons fired at different locations in the network.”
“Our results therefore show that the precise and personalised
planning of radiological investigations is of tremendous importance,”
says Schöpf. Following this investigation, the best proposed solution is
then drawn up within the multidisciplinary team meetings with the
patient.
Five research clusters at the MedUni Vienna
The study falls within
the remit of the Medical Neurosciences and Medical Imaging research
cluster at the MedUni Vienna. There are five research clusters in total.
These specialist areas are increasingly focusing on fundamental and
clinical research at the MedUni Vienna. The other three research
clusters are Immunology, Cancer Research / Oncology and Cardiovascular
Medicine.
