  2. 6. Intra-Aneurysm Sac Pressure and Clinical Results after Endovascular Repair of Abdominal Aortic Aneurysms

    Author : Nuno Dias; Vaskulära sjukdomar - kliniska studier; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostics; Diagnostik; Open Repair; EVAR; Endovascular Aneurysm Repair; Pressure; Abdominal Aortic Aneurysm;

    Abstract : AIM: The aim was to evaluate the results of endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) in terms of intra-AAA pressure and clinical outcomes. METHODS AND RESULTS: 0.014-inch guide-wire-mounted tip-pressure sensors were used for direct intra-aneurysm sac pressure measurement (DISP) through translumbar puncture of the AAA. READ MORE

  4. 7. 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

    Author : Barbara Elmståhl; Malmö Diagnostisk radiologi; []
    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

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

    Author : Henrik Engblom; Lund Klinisk fysiologi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 9. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function

    Author : Carolin Freccero; Kirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; wavelength; sympathetic vasodilatation; sympathetic vasoconstriction; sympathetic nerve function; parasympathetic nerve function; laser Doppler perfusion imaging; laser Doppler perfusion monitoring; finger skin blood flow; fibre separation; contralateral cooling; Concentration; Fysiologi; Cardiovascular system; Kardiovaskulära systemet; Diagnostik; Diagnostics;

    Abstract : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. READ MORE

  7. 10. ­­­Visual assessment of perfusion and metabolism in neurodegenerative dementia

    Author : David Fällmar; Elna-Marie Larsson; Lena Kilander; Mark Lubberink; Ian Law; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dementia; Neurodegenerative; Brain imaging; Diagnostics; Neuroradiology; Neuroimaging; Demens; Neurodegenerativ; Hjärnavbildning; diagnostik; Neuroradiologi; Neuroimaging; Radiology; Radiologi;

    Abstract : A worldwide demographic shift is currently occurring, with rapidly increasing numbers of elderly individuals. Since the incidence of neurodegenerative disease generally increases with age, this entails an increase in dementia prevalence. READ MORE
