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 کاملHyperactivity of 99mTc-HMPAO within 6 hours in patients with acute ischemic stroke.
UNLABELLED Intraarterial thrombolytic therapy has been used recently for treatment of acute ischemic stroke within 6 h after onset. Although hypoactivity of 99mTc-hexamethylpropyleneamine oxime (HMPAO) in stroke has been well documented, hyperactivity of HMPAO has not been evaluated in sufficient detail. The purpose of this study was to evaluate the incidence and clinical importance of hyperact...
متن کاملdysphagia in acute ischemic stroke
Introduction: Swallowing dysfunction complicates acute strokes in 25-32% of cases and directly affects patientschr('39') prognosis and recovery. Dysphagia complicates the course of acute strokes through its potential of the development of chest infection, nutritional problems, and dehydration. Dysphagia is also an independent predictor of respiratory morbidity and mortality in acute stroke. In...
متن کاملNoninvasive imaging of radiolabeled exosome-mimetic nanovesicle using 99mTc-HMPAO
Exosomes known as nano-sized extracellular vesicles attracted recent interests due to their potential usefulness in drug delivery. Amid remarkable advances in biomedical applications of exosomes, it is crucial to understand in vivo distribution and behavior of exosomes. Here, we developed a simple method for radiolabeling of macrophage-derived exosome-mimetic nanovesicles (ENVs) with (99m)Tc-HM...
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...
