BACKGROUND AND PURPOSE Extracorporeal rheopheresis is a safe method to optimize hemorheology. Our aim was to determine whether treatment with extracorporeal rheopheresis in patients with acute ischemic hemispheric stroke improves cerebral perfusion as assessed with serial 99mTc-ethyl-cysteinate-dimer single-photon emission CT (99mTc-ECD SPECT). We also investigated how clinical outcome is assoc...
Nasu-Hakola disease is a rare, recessively inherited disease characterized by presenile dementia and bone cysts. Until now, no evidence of subclincal pathological changes in individuals heterozygous for the mutations underlying Nasu-Hakola disease has been reported. We performed a functional neuroimaging (99mTc-ECD SPECT) and neuropsychological study of healthy members of an Italian family carr...
We described a case of a 6 year old boy presenting with transient dizziness with weakness of left limbs. MRI showed the presence of a diffusely dilated extensive vascular lesion mainly located in the corpus callosum, right frontal and temporal lobes. Digital subtraction angiography (DSA) revealed a large hypervascular lesion with a diffuse arterial supply. 99mTc-ECD SPECT cerebral blood flow pe...
BACKGROUND Major depressive disorder (MDD) is a common mental disorder worldwide, but now there is a lack of clinically effective assessment and management of MDD. In this study, we used technetium-99 m ethylcysteinate dimer ([99mTc]ECD) SPECT/CT to characterize the regional cerebral blood flow (rCBF) status of MDD patients, and to explore an objective image assessment model of MDD which is non...
UNLABELLED Anatomical localization requires establishing an anatomical space within the image matrix. We developed a fast, fully automated method to establish the image orientation for 99mTc-ethylcysteinate dimer (ECD) brain SPECT images. METHODS The image orientation of ECD brain SPECT images was established in four stages. First, the brain surface was edge-detected as an isosurface at an ad...
