Acetazolamide, a selective-inhibitor of carbonic anhydrase. Has been shown to induce a rapid increase in cerebral blood flow by acidifying cerebral extracellular tluid in large doses. In order to assess the cerebral blood flow reserve, we investigated 14 patients with ischemic cerebrovascular disease using Tc-99m HMPAO SPECT before and after administration of acetazolamide.The patients after acetazolamide challenge showed variable pattems of vasodilating capacity which were classified as follows: group I. Accentuation of abnormal perfusion pattem; group II, no change in abnormal perfusion pattern: and group III. Blunting of abnormal perfusion pattern. Thirty-six percent of the patients studied qualified for group I. The p?tients in group I seem to have decreased vasodilating reserve in the area of cerebral ischemia. They are most likely to benefit by medical or surgical efforts to augment CBF delivery. Tc-99m HMPAO-SPECT with acetazolamide flow challenge may serve as an objective. Clinically accessible method for assessing blood flow reserve and as a kind of guide for the therapeutic strategy.

The use of interictal Tc-99m HMPAO SPECT images for localizing epileptic foci is limited by low sensitivty and specificity, while the routine use of ictal images is impractical for obvious reasons. To find out the possibility to solve these problems. We tried to stimulate the epileptic foci by provocation technique.

A new radiopharmaceutical, technetium-99m hexamethylpropyleneamine oxime(99mTc-HMPAO), has been reported to cross the blood-brain-barrier and to distribute in brain in proportion to regional blood flow. Measurement of cerebral blood flow with single photon emixxion computed tomography(SPECT) was performed using 99mTc-HMPO in 46 patients and clinical analysis was done. Decreased regional cerebral perfusion was observed in 41 cases. Moreover eight cases of them who had normal X-ray C-T scan revealed positive finding on SPECT. We porpose that 99mTc-HMPAO SPECT seems to be a useful diagnostic method for evaluation of ischemic cerebral lesions.
