  1. 6. Polycystic ovary syndrome - morphologic and dynamic evaluation by magnetic resonance imaging

    Författare :Henrik Leonhardt; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycystic ovary syndrome; PCOS; magnetic resonance imaging; MRI; ultrasonography; three-dimensional imaging; adrenal hyperplasia; body composition; uterine morphology; uterine peristalsis; ovarian morphology; ovarian perfusion; antral follicle count; AMH; diagnostic accuracy;

    Sammanfattning : Polycystic ovary syndrome (PCOS) is a complex endocrine disorder, affecting up to 15% of women of reproductive age. The syndrome is characterized by oligo-anovulation, hyperandrogenism and polycystic ovaries. What constitutes the best definition of PCOS is still a matter of debate. LÄS MER

  3. 7. DIXI – a Hybrid Pixel Detector for X-ray Imaging

    Författare :Fredrik Edling; Richard Brenner; Leif Gustafsson; Camilla Rönnqvist; Peter Fischer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation sciences; hybrid pixel detector; photon-counting; X-ray; imaging; simulation; Strålningsvetenskap; Radiation biology; Strålningsbiologi;

    Sammanfattning : Medical X-ray imaging is an important tool in diagnostic radiology. The ionising-radiation dose to the patient is justified by the clinical benefit of the examination. Nonetheless, detectors that operate at even lower doses and provide more information to the radiologist are desired. LÄS MER

  4. 8. Magnetic resonance imaging and diffusion tensor imaging after brachial plexus injury and repair : Experimental and clinical study

    Författare :Grainne Bourke; Mikael Wiberg; Lev N. Novikov; Lars Dahlin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brachial Plexus; Magnetic Resonance Imaging; Neonatal; Diffusion Tensor Imaging;

    Sammanfattning : Brachial plexus injuries (BPI) cause permanent upper limb paralysis and serious disability in adults and children. Timely identification of the severity of nerve injury and early appreciation of the inane potential for recovery would revolutionise management. LÄS MER

  5. 9. Human brain function evaluated with rCBF-SPECT : memory and pain related changes and new diagnostic possibilities in Alzheimer’s disease

    Författare :Torbjörn Sundström; Katrine Riklund; Rimma Danielsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain imaging; rCBF; SPECT; early diagnosis; brain atlas; HMPAO; Alzheimer´s disease; Whiplash; neuropsychological function; episodic memory; Diagnostic radiology; Diagnostisk radiologi;

    Sammanfattning : The aim of this doctoral thesis was to study the influence of memory, pain, age and education on the regional cerebral blood flow (rCBF), i.e. brain function, in early Alzheimer's disease (AD) and in chronic neck pain patients in comparison to healthy controls and in healthy elderly per se.

  7. 10. Cancer imaging and image analysis methods in whole-body MRI and PET/MRI

    Författare :Therese Sjöholm; Joel Kullberg; Filip Malmberg; Robin Strand; Håkan Ahlström; Einar Heiberg Brandt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; diffusion weighted imaging; positron emission tomography; whole-body imaging; normal atlas; CAR T-cell therapy; lymphoma; medical image analysis; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Diagnostic medical imaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET) can provide structural and functional assessments of the whole body. This has great value for potentially systemic diseases such as cancer. LÄS MER
