    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endovascular treatment; medical instrumentation; tomography; radiology; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; Diffusion and perfusion; Complications; Magnetic Resonance Imaging; Cerbrovascular malformations; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : 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. 12. Are gadolinium contrast media really less nephrotoxic than iodine agents in radiographic examinations? A comparison in relation to their ability to attenuate x-rays in a pig model

    University dissertation from Department of Clinical Sciences, Lund University

    Author : Barbara Elmståhl; Lund University.; Lunds universitet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiography; Computed tomography; toxicity; Contrast media; Glomerular filtration; Gadolinium; Iodine; Kidney failure; Nephrotoxicity.; Medicin människa och djur ; radiology; Clinical physics; Medicine human and vertebrates ; tomography; medical instrumentation; Diagnostik; Diagnostics; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi;

    Abstract : Purpose: To confront the statement that gadolinium contrast media (Gd-CM) are less nephrotoxic than iodine contrast media (I-CM) when used in x-ray angiographic and computed tomographic (CT) examinations. Methods: I) For CT measurements (mean density in Hounsfield numbers) 20-mL syringes filled with I- and Gd-CM at 0.01, 0.02, 0. READ MORE

  3. 13. MRI assessment of haemophilic arthropathy

    University dissertation from Institutionen för kliniska vetenskaper, Lunds universitet

    Author : Björn Lundin; Lund University.; Lunds universitet.; [2007]
    Keywords : 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;

    Abstract : 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.

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

    University dissertation from Diagnostisk radiologi, Lunds Universitet

    Author : Danielle van Westen; Lund University.; Lunds universitet.; [2006]
    Keywords : 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;

    Abstract : 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).

  5. 15. Simulation supported training in oral radiology methods and impact on interpretative skill

    University dissertation from Umeå : Odontologi

    Author : Tore Nilsson; Umeå universitet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virtual reality; simulation; simulator; radiology; radiography; learning; skill acquisition; visual-spatial ability; parallax; MEDICINE Physiology and pharmacology Radiological research Radiology; MEDICIN Fysiologi och farmakologi Radiologisk forskning Radiologi; odontologi; Odontology;

    Abstract : Simulation is an important tool when training is hazardous, time consuming, or expensive. Simulation can also be used to enhance reality by adding features normally not available in the real world. READ MORE
