low flow to the left hemisphere. These indications of low neural activity in the left hemisphere are consistent with early reports on lateralised features in the EEG in dysphasia.17 In conclusion, we have shown that various developmental learning disabilities are associated with regional cerebral blood flow abnormalities as assessed with SPET. It may be that the phylogenetically recent linguist...

The objectives were to study ultrasound (US), magnetic resonance imaging (MRI), single photon emission tomography (SPET) and brainstem auditory evoked potentials (BAEP) as structural and functional imaging methods for the prediction of later neuromotor outcome and to assess the reliability of auditory brainstem responses (ABR), transient evoked otoacoustic emissions (TEOAE) and free-field audit...

Due to the rapid development of modern imaging methods and also of medical oncology, there has been a significant progress in diagnosis and treatment of malignant lymphomas in the last few years. Nuclear medicine (NM) imaging methods gained new perspectives via the so called hybrid technologies-single-photon emission tomography combined with computed tomography (SPET/CT), positron emission tomo...

Functional neuroimaging provides a direct way of investigating the pathophysiology of schizophrenia in vivo. The function of neurotransmitters implicated in schizophrenia, such as dopamine and glutamate, can be assessed using molecular imaging techniques such as positron emission tomography (PET), single-photon emission tomography (SPET) and magnetic resonance spectroscopy (MRS). Regional brain...

The first functional neuroimaging studies of schizophrenia, using single photon (SPET) and positron emission tomography (PET), led to the notion of abnormal 'hypofrontality' (Ingvar & Franzen, 1974). Although consistent with data linking schizophrenia with deficits in frontal function, the popularity of'hypofrontality' gradually faded as technically and methodologically more sophisticated studi...

The study from Mehrazin et al. in HJNM 2011; 14(3): 243-50 on the neuropsychology, morphological computerized tomography (CT) and functional neuroimaging with 99mTc-labelled ethylene cysteinate dimer single-photon emission tomography (SPET) in mild traumatic brain injury (MTBI) is an interesting new approach to a disease condition which is often neglected or denied. Related to the above, we may...

This study was performed to find out the left ventricular ejection fraction (LVEF) and right ventricular ejection fraction (RVEF) in patients with dilated cardiomyopathy (DCM) by using commercially available automated gated blood pool scintigraphy (GBPS) processing software and to correlate it with first pass radionuclide ventriculography (FPRNV) and planar multigated acquisition (MUGA).
