  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. Acute kidney injury, outcome studies

    Författare :Max Bell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Acute kidney injury (AKI) is a complex syndrome for which no effective treatment exists, and our understanding of this condition is limited. If the acute kidney injury is severe enough to require renal replacement therapy, mortality rates at six months are around 60%. LÄS MER

  4. 13. 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

    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 14. Oral anticoagulation treatment in atrial fibrillation - To bleed or not to bleed, that is the question

    Författare :Mattias Wieloch; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anticoagulation; atrial fibrillation; hemorrhage; kidney; warfarin; epidemiology; stroke;

    Sammanfattning : Background: Oral antigoagulation treatment (OAT) with warfarin have a narrow therapeutic window and patients exhibit a highly variable doseresponse that is attributable to genetic, disease-related,and environmental factors as well as prescription and nonprescription drugs, dietary vitamin K and alcohol. The effect of warfarin treatement on blood coagulation is measured using international normalized ratio (INR). LÄS MER

  7. 15. 3D Rotational Angiography of Transplanted Renal Arteries : A Clinical and Experimental Study

    Författare :Gaute Hagen; Anders Magnusson; Jonas Wadström; Jarl Jakobsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Kidney; transplantation; renal angiography; renal arteries; stenosis or obstruction; imaging; three-dimensional; artifacts; Radiologisk forskning; Radiological research; Radiologisk forskning;

    Sammanfattning : Three-dimensional rotational angiography (3D-RA) is an established method within the field of interventional neuroradiology. The method has also a great potential in other areas with a complicated arterial anatomy. LÄS MER
