Acetazolamide vasoreactivity evaluated by transcranial power harmonic imaging and Doppler sonography

Autor: T, Shiogai, K, Ikeda, A, Morisaka, Y, Nagakane, T, Mizuno, M, Nakagawa, H, Furuhata

Publikováno v: Acta neurochirurgica. Supplement. 102

Cerebral vasoreactivity (CVR) in the major cerebral arteries evaluated by transcranial Doppler sonography has shown some correlation with CVR in the brain tissue measured by other neuroradiological modalities. To clarify vasoreactive differences in t

Quantitative evaluation of cerebrovascular reactivity in brain tissue by a refill kinetic method of transcranial ultrasonic perfusion imaging: a comparison with Doppler sonography

Autor: T, Shiogai, A, Morisaka, N, Takayasu, K, Yoshikawa, T, Mizuno, M, Nakagawa, H, Furuhata

Publikováno v: Acta neurochirurgica. Supplement. 95

To confirm the reliability of a refill kinetic method of ultrasonic harmonic perfusion imaging (HPI) capable of quantifying separate parameters of microvascular blood flow velocity and volume in brain tissue, we evaluated acetazolamide (ACZ) cerebrov

Acetazolamide vasoreactivity evaluated by transcranial harmonic perfusion imaging: relationship with transcranial Doppler sonography and dynamic CT

Autor: T, Shiogai, M, Koshimura, Y, Murata, H, Nomura, A, Doi, M, Makino, T, Mizuno, K, Nakajima, H, Furuhata

Publikováno v: Acta neurochirurgica. Supplement. 86

To establish the reliability and clinical significance of transcranial ultrasonic harmonic perfusion imaging (HPI), we evaluated HPI's relationships with transcranial Doppler (TCD) and with dynamic CT (DCT), during acetazolamide (ACZ) vasoreactivity

Acetazolamide vasoreactivity in persistent vegetative state and vascular dementia evaluated by transcranial harmonic perfusion imaging and Doppler sonography

Autor: T, Shiogai, M, Koshimura, C, Uebo, M, Makino, T, Mizuno, K, Nakajima

Publikováno v: Acta neurochirurgica. Supplement. 87

To clarify the pathophysiological differences of the cerebrovascular reserve capacity in relation to cerebral cognitive impairments between persistent vegetative state (PVS) and vascular dementia (VD), we evaluated acetazolamide (ACZ) vasoreactivity

Comparative effects of hypothermia, barbiturate, and osmotherapy for cerebral oxygen metabolism, intracranial pressure, and cerebral perfusion pressure in patients with severe head injury

Autor: I, Nara, T, Shiogai, M, Hara, I, Saito

Publikováno v: Acta neurochirurgica. Supplement. 71

In order to select the optimal neurointensive treatment for patients with severe head injury and intracranial hypertension, the effects of hypothermia (HT), barbiturates (BT), and osmotic agents (OT) on focal and diffuse cerebral oxygen metabolism we

Morphological and hemodynamic evaluations by means of transcranial power Doppler imaging in patients with severe head injury

Autor: T, Shiogai, K, Nagayama, G, Damrinjap, K, Saruta, M, Hara, I, Saito

Publikováno v: Acta neurochirurgica. Supplement. 71

The following conditions of 17 patients with severe head injury (ages 9-76; mean 37:12 focal and 5 diffuse injuries) were evaluated during acute phase (1-14 days after injury, mean 5) by transcranial power Doppler imaging (PDI), a new color Doppler u

Consensus opinion on diagnosis of cerebral circulatory arrest using Doppler-sonography: Task Force Group on cerebral death of the Neurosonology Research Group of the World Federation of Neurology

Autor: X, Ducrocq, W, Hassler, K, Moritake, D W, Newell, G M, von Reutern, T, Shiogai, R R, Smith

Publikováno v: Journal of the neurological sciences. 159(2)

Oscillating flow or systolic spikes are typical Doppler-sonographic flow signals found in the presence of cerebral circulatory arrest, which if irreversible, results in brain death. The Neurosonology Research Group (NSRG) of the World Federation of N
