Abstract |
Minima1 deterioration of cerebral perfusion or
microanatomical changes were undetectable on
conventional Brain CT or MRI. So evaluation of focal
functional changes of the brain parenchyme is essential
in chronic head injury patients, who did not show focal
anatomical changes on these radiological studies.
However, the patients who had longstanding neurologic
sequelae following head injury, there had been no
available imaging modalities for evaluating these
patients precisely. Therefore we tried to detect the
focal functional changes on the brain parenchyme using
Tc-99m-HMPAO Brain SPECT on the patients of chronic
head injuries. Twenty three patients who had suffered
from headache, memory dysfunction, personality change
and insomnia lasting more than six months following
head injury were included in our cases, which showed no
anatomical abnormalities on Brain CT or MRI. At first
they underwent psychological test whether the symptoms
were organic or not. Also we were able to evaluate the
cerebral perfusion changes with Tc-99m-HMPAO Brain
SPECT in 22 patients among the 23, which five patients
were focal and 17 patients were nonfocally diffuse
perfusion changes. Thus we can predict the perfusion
changes such as local vascular deterioration or
functional defects using Tc-99m-HMPAO Brain SPECT in
the patients who had suffered from post-traumatic
sequelae, which changes were undetectable on Brain CT
or MRI. |
