Abstract
|
|
|
Brain SPECT studies with 99mTc-HMPAO (Hexa Methyl-Propylen-Amin-Oxim) were perfomed in seven patients patients with head trauma who showed no mass lesion on brain CT (or MRI) scan and whose mean GCS were below 7 to verify the relationship between
regional cerebral blood flow (rCBF), level of consciousness and clinical outcome. Initial and follow up SPECT were performed, and obtained the r-ray counts on the portion which showed many changes in brain SPECT and its percentage were compared
to
the
control group.
Comparison of the initial and follow up studies revealed that r-ray counts and its percentage declined to very low level in one patient who died, but 5 patients whose GCS improved to 14 showed increased r-ray counts and its percentages which
meant
increased regional cerebral blood flow. However, how long the increased state of rCBF, which thought to be luxury perfusion, would last needs to be determined. It seems to be clear that the change of regional cerebral blood flow could be
determined
by
comparing the rates of changed r-ray counts with 99 mTc-HMPAO SPECT.
