99mTc-HMPAO-SPECT with acetazolamide challenge to detect hemodynamic compromise in occlusive cerebrovascular disease.
BACKGROUND AND PURPOSE Insufficiency of collateral supply may lead to low-flow infarcts in severe occlusive cerebrovascular disease. The aim of this study was to evaluate the feasibility of technetium-99m-labeled hexamethylpropyleneamine oxime (99mTc-HMPAO) single-photon emission computed tomography (SPECT) to assess hemodynamic compromise in the anterior circulation. METHODS Cerebral blood f...
متن کامل99mTc-bicisate and 99mTc-HMPAO SPECT imaging in early spontaneous reperfusion of cerebral embolism.
Two patients with a cerebral embolism were evaluated by using both 99mTc-ethyl cysteinate dimer (ECD, or Bicisate) and 99mTc-hexamethylpropyleneamine oxime (HMPAO) single-photon emission computed tomography (SPECT). In one patient, 99mTc-ECD SPECT images revealed hypoactivity in a reflow hyperemic area where an infarct was seen later on CT scans. In another patient, a reperfused area showed hyp...

متن کاملCerebral perfusion changes in older delirious patients using 99mTc HMPAO SPECT.
BACKGROUND Prior studies describe variable cerebral blood flow changes in delirium. This study aims to investigate cerebral blood flow changes in older hospitalized patients with delirium, the population in which most cases of delirium occur. METHODS Participants included hospitalized general medical patients aged 65 years and older with documented delirium and no relevant medical conditions ...
متن کاملThe diagnostic difference between 18F- FDG PET and 99mTc-HMPAO SPECT perfusion imaging in assessment of Alzheimer's disease
Introduction:Brain imaging with F-18 fluorodeoxyglucose (18F-FDG) positron emission tomography or Tc-99m hexamethylpropyleneamine oxime (99mTc-HMPAO) SPECT is widely used for the evaluation of Alzheimer's dementia (AD); we aim to assess superiority of one method over the other. Methods: Twenty four patients with clinical diagnosi...
