  1. 16. Screening for Atherosclerosis with Magnetic Resonance Imaging and Ultrasound

    Författare :Christina Lundberg; Lars Johansson; Håkan Ahlström; Lars Lind; Anders Wanhainen; Hansen Tomas; Kenneth Caidahl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Atherosclerosis is a major cause of death and disability worldwide. Although traditional risk factors can identify the healthy or severely affected individuals, sudden lethal outcome is still frequent in those suggested as intermediate in risk for cardiovascular events (CVE).

  3. 17. Magnetic Resonance Imaging of Human Brown Adipose Tissue : Methodological Development and Application

    Författare :Elin Lundström; Joel Kullberg; Håkan Ahlström; Lars Johansson; Robin Strand; Sven Månsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brown adipose tissue; Magnetic resonance imaging; Positron emission tomography; Image segmentation; Glucose metabolism;

    Sammanfattning : Brown adipose tissue (BAT) is a thermogenic organ with the main human depot located in the cervical-supraclavicular (sBAT) region. BAT is proposed as a potential therapeutic target for obesity and diabetes. LÄS MER

  5. 19. Quantitative Tracer Based MRI Perfusion : Potentials and Limitations

    Författare :Arvid Morell; Atle Bjørnerud; Håkan Ahlström; Linda Knutsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; Perfusion; Contrast agent; Relaxivity; Radiology; Radiologi;

    Sammanfattning : Tracer based MRI perfusion measurements is a clinically useful tool to assess regional distributions of tissue blood flow and volume. The method may be based on any of the three relaxation mechanisms T1, T1 and T2*, the latter denoted DSC-MRI being the most common. LÄS MER

  7. 20. Whole-Body MRI including Diffusion-Weighted Imaging in Oncology

    Författare :Firas Mosavi; Håkan Ahlström; Lennart Blomqvist; Uppsala universitet; []
    Nyckelord :Diffusion-weighted imaging; Whole-body MRI; NaF PET CT; FDG PE CT; apparent diffusion coefficient;

    Sammanfattning : Cancer is one of the major causes of worldwide mortality. Imaging plays a vital role in the staging, follow-up, and evaluation of therapeutic response in cancer patients. Whole-body (WB) magnetic resonance imaging (MRI), as a non-ionizing imaging technique, is a promising procedure to assess tumor spreading in a single examination. LÄS MER
