Comparison of[F]FDG-PET, [Tc]-HMPAO-SPECT, and [I]-iomazenil-SPECT in localising the epileptogenic cortex
Objectives—Firstly, to compare the findings of interictal F-fluorodeoxyglucose (FDG) positron emission tomography (PET) and of single photon emission computed tomography (SPECT) using Tc-hexamethyl propylene-amine-oxime (HMPAO) and I-iomazenil in localising the epileptogenic cortex in patients who were candidates for epilepsy surgery, but in whom clinical findings, video EEG monitoring (V-EEG),...
متن کاملAltered SPECT 123I-iomazenil Binding in the Cingulate Cortex of Children with Anorexia Nervosa
Several lines of evidence suggest that anxiety plays a key role in the development and maintenance of anorexia nervosa (AN) in children. The purpose of this study was to examine cortical GABA(A)-benzodiazepine receptor binding before and after treatment in children beginning intensive AN treatment. Brain single-photon emission computed tomography (SPECT) measurements using (123)I-iomazenil, whi...
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 کاملIs 11C-flumazenil PET superior to 18FDG PET and 123I-iomazenil SPECT in presurgical evaluation of temporal lobe epilepsy?
OBJECTIVE To determine the contribution of 18FDG PET, 11C-flumazenil PET, and 123I-iomazenil SPECT to the presurgical evaluation of patients with medically intractable complex partial seizures. METHODS Presurgical evaluation was performed in 23 patients, who were considered candidates for temporal lobe resective surgery (14 females and nine males with a median age of 34 (range 13 to 50) years...
متن کاملAbsolute activity quantitation in simultaneous 123I/99mTc brain SPECT.
UNLABELLED Dual-isotope imaging can allow simultaneous assessment of brain perfusion using a 99mTc-labeled tracer and neurotransmission using an 123I-labeled tracer. However, the images are affected by scatter, cross talk, attenuation, distance-dependent collimator response (DCR), and partial-volume effect. We determined the accuracy and precision of activity quantitation in simulated normal an...
