  1. 11. Assessment of Renal Physiology Using Functional MRI

    Författare :Per Eckerbom; Per Liss; Fredrik Palm; Peter Hansell; Jarl Jakobsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kidney; Renal; MRI; Phase contrast; ASL; BOLD; DWI; T1; COVID-19; Radiology; Radiologi;

    Sammanfattning : Kidney injury is a major cause of morbidity and mortality throughout the world, leading to substantial individual suffering and to a heavy financial burden for the society. A large number of common conditions such as diabetes, hypertension, autoimmune diseases and infections are highly associated with kidney injury. LÄS MER

  3. 12. Cross-Correlator Implementations Enabling Aperture Synthesis for Geostationary-Based Remote Sensing

    Författare :Erik J Ryman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-custom; signal processing; synthetic aperture; Cross-correlation; interferometric imaging; ASIC; remote sensing;

    Sammanfattning : An ever-increasing demand for weather prediction and high climate modelling accuracy drives the need for better atmospheric data collection. These demands include better spatial and temporal coverage of mainly humidity and temperature distributions in the atmosphere. LÄS MER

  4. 13. Dose painting : Can radiotherapy be improved with image driven dose-responses derived from retrospective radiotherapy data?

    Författare :Eric Grönlund; Anders Ahnesjö; Silvia Johansson; Daniela Thorwarth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; functional imaging; dose painting; dose painting by numbers; robust optimization; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : The main aim of curative radiotherapy for cancer is to prescribe and deliver doses that eradicate the tumor and spare the normal healthy tissues. Radiotherapy is commonly performed by delivering a homogeneous radiation dose to the tumor. LÄS MER

  5. 14. Optimized MRI methods for simplified oncological imaging in pancreas and liver

    Författare :Nikolaos Kartalis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Recent technological advances within the fields of Abdominal Imaging have revolutionised oncological imaging. In the investigation of the solid organs in the upper abdomen, extensive examinations are used in order to obtain accurate information. LÄS MER

  7. 15. Experimental and clinical perspective on stroke : evaluation by behavior, magnetic resonance imaging and morphology

    Författare :Zhengguang Chen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cerebral ischemia; stroke; penumbra; behavior; hemodynamics; MRI; perfusion; diffusion; relaxation times; rat;

    Sammanfattning : In order to further improve the diagnostic power of the NEU technique in the use for clinical evaluation of brain lesions, like in stroke patients, a biological model system had to be implemented where the relevant aspects of the brain injury and its effects could be mimicked. Two well controlled and reproducible rat models were chosen, one developed by Bjelke et al. LÄS MER
