Increased uptake of 99mTc-HMPAO in necrotic brain tumors.
99mTc complex of hexamethylpropylene amine oxime (99mTc-HMPAO), which has been used as a tracer for regional cerebral blood flow (rCBF), has been shown to localize in primary brain tumors with wide spectrum of its uptake. The causes of the wide spectrum of tumor uptake, however, has not been understood in detail. We performed autoradiographic study with this agent to get further knowledge about...
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...
متن کاملEffect of linearization correction on statistical parametric mapping (SPM): a 99mTc-HMPAO brain perfusion SPECT study in mild Alzheimer's disease.
OBJECTIVE Statistical parametric mapping (SPM) was employed to investigate the regional decline in cerebral blood flow (rCBF) as measured by 99mTc-hexamethyl propylene amine oxime (HMPAO) single photon emission computed tomography (SPECT) in mild Alzheimer's disease (AD). However, the role of the post reconstruction image processing on the interpretation of SPM, which detects rCBF pattern, has ...
متن کاملPerfusion scanning using 99mTc-HMPAO detects early cerebrovascular changes in the diabetic rat
BACKGROUND 99mTc-HMPAO is a well-established isotope useful in the detection of regional cerebral blood flow. Diabetes gives rise to arterial atherosclerotic changes that can lead to significant end organ dysfunction, prominently affecting perfusion to the heart, kidneys, eyes and brain. In the current study, we investigated the role of 99mTc-HMPAO cerebral perfusion scans in detecting early va...
