  1. 1. MRI with MR Angiography in Endovascular Repair of Abdominal Aortic Aneurysms

    Författare :Lena Engellau; Malmö Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; tomography; radiology; Clinical physics; Contrast media complications; Cost analysis; MR velocity mapping; Artefacts; MR imaging safety; MR angiography; MR imaging; Endovascular repair; Stent-graft; aortic; Aneurysm;

    Sammanfattning : The aim of this study was to evaluate MRI with contrast enhanced MR angiography (MRI/CE MRA) as imaging method before and after endovascular repair of abdominal aortic aneurysms (AAA). A 1.5 T scanner was used for all examinations. In this prospective study 26 consecutive patients were included. LÄS MER

  2. 2. Proton Relaxation Properties of a Particulate Iron Oxide MR Contrast Agent in Different Tissue Systems : Implications for Imaging

    Författare :Atle Bjørnerud; Graham A. Wright; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Iron oxide nanoparticles; USPIO; NC100150 Injection; water exchange limited relaxation; MR perfusion imaging.; Onkologi; Oncology; Onkologi; radiologi; Radiology;

    Sammanfattning : Knowledge of the relationship between in vivo contrast agent concentration and magnetic resonance (MR) signal response is an important requirement in contrast enhanced MR imaging in general and in MR based perfusion imaging in particular. This relationship is a complex function of the properties of the contrast agent as well as the structure of the target tissue. LÄS MER

  3. 3. Radiography and bone scintigraphy in osteoarthritis of the knee: comparison with MR imaging

    Författare :Torsten Boegård; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; MR imaging; bone scintigraphy; osteophyte; joint space width; weight-bearing; radiograms; Knee joint; osteoarthritis; tomografi; medicinsk instrumentering;

    Sammanfattning : The aim was to compare radiography of the tibiofemoral joint (TFJ) and the patellofemoral joint (PFJ), as well as bone scinigraphy with MR imaging in middle-aged individuals with chronic knee pain in the format of a prospective study of knee osteoarthritis. Individuals aged 35-54 years with chronic knee pain were identified. LÄS MER

  4. 4. Magnetic Resonance Imaging in Parkinsons's disease and related disoders

    Författare :Yulia Surova; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mr Imaging; DTI; Parkinson s disease; Progressive supranuclear palsy; Multiple system atrophy;

    Sammanfattning : Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. LÄS MER

  5. 5. Functional and morphological MR studies in congenital cardiovascular malformations

    Författare :Catarina Holmqvist; Lund Diagnostisk radiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; Contrast-enhanced MR angiography.; Coarctation; Intra-cardiac shunts; Conduits; Tetralogy of Fallot; Function; Flow; MR velocity mapping; Infants; Children; Magnetic Resonance Imaging; Angiocardiography; Heart; Congenital heart defects; medical instrumentation; tomography; radiology; Clinical physics;

    Sammanfattning : The aim of this study was to evaluate new MR techniques permitting qualitative and quantitative analysis of cardiac function and measurement of velocity and flow, and later on contrast-enhanced MR angiography, techniques largely unexplored in children with CHD. Infants with tetralogy of Fallot and pulmonary atresia with ventricular septal defect were examined pre-operatively. LÄS MER
