The aim of this work is to evaluate diagnostic value liver non-contrast perfusion in prediction visceropathies (sialadenitis and hepatic encephalopathy) patients with diffuse diseases (DLD). Clinical laboratory data (including the Raitan test), results MRI MR (ASL-perfusion) brain assessment head neck soft tissues were estimated a group DLD. Potentials ASL for encephalopathy sialadenitis are de...

BACKGROUND The present study was carried out to evaluate cerebral perfusion in multiple sclerosis (MS) patients with a moderate to severe stage of disease. Some patients underwent hyperbaric oxygen therapy (HBOT) and brain perfusion between before and after that was compared. METHODS We retrospectively reviewed 25 secondary progressive (SP)-MS patients from the hospital database. Neurological...

Brain perfusion SPECT is a functional neuroimaging technique that allows noninvasive study of physiologic and physiopathologic events in the human brain. With the appropriate technique and careful interpretation of the information provided, brain perfusion SPECT has proven potential for patient management. SPECT has clinical value in the diagnosis, therapeutic management, and follow-up of patie...

BACKGROUND In the graph theoretical analysis of anatomical brain connectivity, the white matter connections between regions of the brain are identified and serve as basis for the assessment of regional connectivity profiles, for example, to locate the hubs of the brain. But regions of the brain can be characterised further with respect to their gray matter volume or resting state perfusion. Loc...

Lesion-symptom mapping studies are based upon the assumption that behavioral impairments are directly related to structural brain damage. Given what is known about the relationship between perfusion deficits and impairment in acute stroke, attributing specific behavioral impairments to localized brain damage leaves much room for speculation, as impairments could also reflect abnormal neurovascu...

The main reason for recreational use of cannabis is the 'high', the primary psychotropic effect of Δ9-tetrahydrocannabinol (THC). This psychoactive compound of cannabis induces a range of subjective, physical and mental reactions. The effect on heart rate is pronounced and complicates bloodflow-based neuroimaging of psychotropic effects of THC. In this study we investigated the effects of THC o...

Recent neuroimaging studies show that brain abnormalities in neuromyelitis optica (NMO) are more frequent than earlier described. Yet, more research considering multiple aspects of NMO is necessary to better understand these abnormalities. A clinical feature of relapsing NMO (RNMO) is that the incremental disability is attack-related. Therefore, association between the attack-related process an...

BACKGROUND AND PURPOSE Intravoxel incoherent motion MRI has been proposed as an alternative method to measure brain perfusion. Our aim was to evaluate the utility of intravoxel incoherent motion perfusion parameters (the perfusion fraction, the pseudodiffusion coefficient, and the flow-related parameter) to differentiate high- and low-grade brain gliomas. MATERIALS AND METHODS The intravoxel ...
