    Sammanfattning : Aims - To describe and evaluate the efficacy and safety of intra-arterial fibrinolysis and the clinical outcome in SAH patients with thromboembolic complications during endovascular coiling of a ruptured aneurysm. (Paper I) - To describe the use and feasibility of magnetic resonance imaging (MRI), especially diffusion and perfusion imaging, in three patients treated endovascularly for various cerebrovascular disorders.

  2. 17. Quantitative assessment of myocardial infarction: On the relationship between anatomy and electrophysiology using MRI and ECG

    Författare :Henrik Engblom; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; magnetic resonance imaging; tomography; medical instrumentation; Clinical physics; radiology; electrocardiography; myocardial infarction; ischemic heart disease; Cardiovascular system; Diagnostics; Diagnostik; Kardiovaskulära systemet;

    Sammanfattning : Both presence and extent of myocardial infarction are important prognostic factors for mortality and quality of life in patients with ischemic heart disease. Thus, it is of great clinical importance to be able to diagnose and characterize myocardial infarction. LÄS MER

  3. 18. MRI at 3 T of brain functions and fibre tracts adjacent to intracranial tumors

    Författare :Danielle van Westen; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; radiology; tomography; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; somatosensory cortex; diffusion magnetic resonance imaging; neoplasms; Functional Magnetic Resonance Imaging;

    Sammanfattning : The aims of the studies were: to evaluate the spatial resolution of fMRI at 3 T by studying fingersomatotopy in area 3 b of the primary sensory area (Paper 1); to investigate the potential of fMRI at 3T as a clinical tool for preoperative evaluation of patients with intracranial tumors (Paper 2); to investigate the effect of glioma resection on the spatial extent of fMRI activation as compared to the normal within-subject variability (Paper 3); to determine whether the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) can distinguish tumor-infiltrated edema of gliomas from pure edema of meningiomas and metastases (Paper 4). Results: Strict somatotopic organisation in the primary sensory cortex was shown in the group average; at the subject level the thumb was located laterally, anteriorly and inferiorly to the little finger in 94 % of subjects (Paper 1).

  4. 19. Ultrasound Examination in Infant Clubfoot with Special Emphasis on the Talonavicular and the Calcaneocuboid Joints

    Författare :Ylva Aurell; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; tomography; medical instrumentation; ultrasonography; Clinical physics; radiology; infant; foot deformities- congenital; anatomy; clubfoot;

    Sammanfattning : The purpose of the study was to develop an ultrasound (US) protocol for evaluating congenital clubfoot pathoanatomy before and during early treatment. By using 3 easily defined and reproducible US projections the talonavicular and the calcaneocuboid joints were assessed. LÄS MER

  5. 20. MRI assessment of haemophilic arthropathy

    Författare :Björn Lundin; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; tomografi; medicinsk instrumentering; medical instrumentation; tomography; radiology; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; Arthropathy; Factor VIII; Factor IX; MRI; Haemophilia; Klinisk fysiologi;

    Sammanfattning : Haemophilia is a recessive genetic bleeding disorder in which coagulation time is prolonged due to the absence or malfunction of either of the serum proteins Factor VIII or IX. Joint destruction following repeated haemarthroses is the main cause of morbidity in haemophiliacs, and such arthropathy can be prevented or postponed by implementing prophylactic therapy with factor concentrate at an early age.
