  1. 1. Investigation of Water Mobility using Diffusion-Sensitive MRI: The Role of q-Space Imaging, High b-Values and Diffusion Time

    Author : Jimmy Lätt; Lunds universitet.; Lund University.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; kurtosis; high b-value; diffusion; diffusion time; NMR; q-space;

    Abstract : Nuclear magnetic resonance (NMR) diffusometry provides important information about molecular motion on a microscopic scale. The advantage of NMR diffusometry is its ability to characterise microstructures non-invasively. This has made the method important not only in chemistry, biochemistry and materials science, but also in medicine. READ MORE

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; Metastasis; ADC; b; Infarct; MRI; Ischemia; Diffusion-Weighted; Diffusion; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Popular Abstract in Swedish Inledning: Stroke är en av de största folksjukdomarna. En patient med akut stroke behöver medicinsk omhändertagande vid en vårdenhet med specialkunskap. För att så tidigt som möjligt kunna planera omhändertagande och ta ställning till behandling är tillförlitlig diagnostik i akutskedet viktig. READ MORE

  3. 3. Computational Diffusion MRI: Optimal Gradient Encoding Schemes

    University dissertation from Department of Diagnostic Radiology, Lund University

  4. 4. Biophysical modelling in diffusion MRI: The role of tissue microstructure and water exchange

    University dissertation from Division of Radiation Physics, Lund University

    Author : Markus Nilsson; Lunds universitet.; Lund University.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diffusion; MRI; tissue microstructure; water exchange; Monte Carlo simulations; white matter;

    Abstract : Popular Abstract in Swedish En magnetkamera kan med hjälp av diffusionsviktad bildtagning användas för att avbilda hjärnans nervsystem. Denna teknik kan utnyttjas för studier av hur hjärnans delar är sammankopplade, men även för att indirekt mäta egenskaper hos hjärnans mikrostruktur. READ MORE

  5. 5. Multiparametric MRI for evaluation of tumour treatment response Studies of 177Lu-octreotate therapy of neuroendocrine tumour

    University dissertation from Division of Radiation Physics, Lund University

    Author : Mikael Montelius; Göteborgs universitet.; Gothenburg University.; [2016]

    Abstract : Clinical assessment of tumour response to treatment largely relies on estimates of tumour size by, e.g., measuring the largest tumour diameters on magnetic resonance (MR) or computed tomography (CT) images, weeks or months after treatment. READ MORE
