Improvement of Cerebral Hypoperfusion with Levothyroxine Therapy in Hashimoto's Encephalopathy Demonstrated by (99m)Tc-HMPAO-SPECT.
BACKGROUND Hashimoto's encephalopathy (HE) is a rare immune-mediated encephalopathy associated with autoimmune Hashimoto's thyroiditis. OBJECTIVES AND METHODS We report on a patient with HE and significant clinical improvement correlating with an increase in cerebral blood flow demonstrated by hexamethylpropyleneamine oxime (HMPAO) single-photon emission computed tomography (SPECT). HMPAO-SPE...
متن کاملStatistical parametric mapping demonstrates asymmetric uptake with Tc-99m ECD and Tc-99m HMPAO SPECT in normal brain.
Tc-99m ethyl cysteinate diethylester (ECD) and Tc-99m hexamethyl propylene amine oxime (HMPAO) are commonly used for single-photon emission computed tomography (SPECT) studies of a variety of neurologic disorders. Although these tracers have been very helpful in diagnosing and guiding treatment of neurologic disease, data describing the distribution and laterality of these tracers in normal res...
متن کاملPerfusion patterns in postictal Tc-HMPAO SPECT after coregistration with MRI in patients with mesial temporal lobe epilepsy
Objectives—To assess patterns of postictal cerebral blood flow in the mesial temporal lobe by coregistration of postictal TcHMPAO SPECT with MRI in patients with confirmed mesial temporal lobe epilepsy. Methods—Ten postictal and interictal Tc-HMPAO SPECT scans were coregistered with MRI in 10 patients with confirmed mesial temporal lobe epilepsy. Volumetric tracings of the hippocampus and amygd...
متن کاملComparison of Different Quantitative Methods and Visual Evaluation on the Tc-99m-HMPAO Brain Perfusion SPET
Objectives Brain perfusion SPECT has been widely used for evaluation of brain perfusion and metabolic status. We aimed to compare different quantitative methods on Tc-99m-HMPAO SPET based on visual evaluation. Materials and Methods: Forty-seven patients were enrolled in this comparative study. Tc-99m-HMPAO brain SPET was performed. For semiquantitative analysis, two orbitomeatal (OM) composite ...
متن کاملTc-99m-HMPAO uptake by bronchoalveolar cells.
Lung uptake of intravenously injected Tc-99m-HMPAO is observed in smokers and in lung toxicity due to various agents. We investigated the Tc-99m-HMPAO uptake of bronchoalveolar lavage (BAL) cells in the lungs after incubation in in vitro conditions (6 patients), intravenous injection (IV) (7 patients) and inhalation (INH) (6 patients) of Tc-99m-HMPAO in order to show whether BAL cells are also ...
