  2. 1. MRI Diagnosis of Intracranial Hemorrhage : Experimental and Clinical Studies

    Author : Montserrat Alemany Ripoll; Kaj Ericsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; hemorrhage; experimental; MRI; T2*-w GE sequence; old microhemorrhages; stroke; Radiologisk forskning; Radiological research; Radiologisk forskning; radiologi; Radiology;

    Abstract : The purpose of this work was to improve the diagnosis of intracranial hemorrhage with MRI, using, among others, T2*-w GE sequences. Various sequences were tested in rabbits at two magnetic field strengths. Then, the most effective technique was applied to stroke patients. READ MORE

  4. 2. Nuclear magnetic resonance and microcirculation: The influence of pulsatile brain-tissue motion on measurements of intravoxel incoherent motion and assessment of haemodynamics using exo- and endogenous tracers

    Author : Ronnie Wirestam; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diagnostic radiology; cortical activation; diffusion; tumor; tumour; ischemic stroke; ischaemic stroke; tracer kinetics; bolus tracking; phase mapping; brain motion; intracranial dynamics; blood flow; haemodynamics; vascularity; MRS; perfusion; MRI; magnetic resonance; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : In this project, the potential of magnetic resonance (MR) imaging and spectroscopy in studies of microcirculation and haemodynamics was evaluated. The spatial and temporal characteristics of human pulsatile brain-tissue movements in healthy individuals, relevant for the understanding of the cerebrospinal-fluid (CSF) circulation and the pathogenesis of hydrocephalus, were thoroughly investigated.

  5. 3. Intranasal Cooling for Cerebral Hypothermia Treatment

    Author : Lucian Covaciu; Sten Rubertsson; Jan Weis; Peter Andrews; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Selective brain cooling; cerebral hypothermia; therapeutic hypothermia; cardiac arrest; stroke; traumatic brain injury; brain temperature; magnetic resonance spectroscopy; trigeminal reflex; Intensive care; Intensivvård; Radiology; Radiologi; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Abstract : The controlled lowering of core body temperature to 32°C to 34°C is defined as therapeutic hypothermia (TH). Therapeutic hypothermia has been shown to improve neurological outcome and survival in unconscious patients successfully resuscitated after cardiac arrest. READ MORE

  6. 4. Therapeutic aspects of oral and pharyngeal swallowing dysfunction. Videoradiographic and videomanometric analyses of adult healthy volunteers and dysphagic patients

    Author : Margareta Bülow; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; tomography; radiology; Clinical physics; Therapy; Videoradiography; Videomanometry; Dysphagia; Dysfunction; Swallowing; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : In this study simultaneous videoradiography and intraluminal manometry (videomanometry) have been used in combination in three studies to analyze how different therapeutic strategies affect the physiology of swallowing in healthy volunteers and in patients with pharyngeal dysfunction. Analyses of healthy volunteers showed few significant measurable effects on the pharyngeal swallow. READ MORE
