Gray-to-white matter ratios of HMPAO in the human brain
Abstract:
The gray-to-white matter ratio of technetium 99m-hexamethylpropyleneamine oxime (99mTc-HMPAO) in 14 anesthetized patients undergoing partial brain resection for treatment of complex partial seizures. The gray-to-white matter ratio of 99mTc-HMPAO was 1.8:1 (standard deviation 0.6) in the temporal lobe. Many of the biopsied specimens demonstrated histopathological abnormalities.
