Detection of acute Epstein Barr virus cerebellitis using sequential brain HMPAO-SPECT imaging. Clinical neurology and neurosurgery, 2004, Volume: 106, Issue:2 We used Technetium-99m hexamethyl propylene amine oxime single-photon emission computed tomography (HMPAO-SPECT) and magnetic resonance imaging (MRI) to evaluate a 30-year-old woman who developed cerebellar dysfunction after infection with Epstein Barr virus. Although no abnormal findings were evident from a brain MRI, the HMPAO-SPECT revealed increased perfusion in both cerebellar hemispheres. The patient improved without specific treatment. Two sequential HMPAO-SPECTs showed gradually reduced hyperperfusion in the cerebellum, which was correlated with her clinical recovery. We suggest that brain HMPAO-SPECT may thus be useful for identifying acute cerebellitis and predicting its clinical outcome.

99mTc-bicisate and 99mTc-HMPAO SPECT imaging in early spontaneous reperfusion of cerebral embolism. AJNR. American journal of neuroradiology, 1999, Volume: 20, Issue:4 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 hyperactivity on 99mTc-ECD SPECT without any abnormality on follow-up CT. 99mTc-ECD represents a potential agent with which to evaluate cerebral tissue viability in early reperfusion after ischemia.
