  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

  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. 4D flow MRI and modelling to assess cerebral arterial hemodynamics : method development and evaluation, with implementation in patients with symptomatic carotid stenosis

    Author : Madelene Holmgren; Anders Eklund; Jan Malm; Anders Wåhlin; Sara Qvarlander; Ronnie Wirestam; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 4D flow MRI; carotid stenosis; cerebral blood flow; cerebral arterial compliance; cerebrovascular resistance; circleof Willis; computational fluid dynamics; magnetic resonance imaging; stroke; vascular disease; Neurology; neurologi;

    Abstract : Blood flow measurements are important for understanding the development of cerebrovascular diseases. With 4D flow magnetic resonance imaging (4D flow MRI), simultaneous velocity measurements are obtained in all cerebral arteries in a scan of about ten minutes. However, 4D flow MRI is a relatively new technique. READ MORE

  7. 5. Measurement and Analysis of Intracardiac Blood Flow and Vortex Ring Formation

    Author : Johannes Töger; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood flow; dynamical systems; magnetic resonance imaging; heart failure; vortex ring formation;

    Abstract : Increased understanding of the pumping mechanics of the heart are of great importance to develop diagnostics, treatment and prognostics for cardiovascular diseases. Blood flow in the heart is connected to its anatomy and function, and may therefore be a sensitive marker of cardiac health and disease. READ MORE
