  1. 1. Core Biopsy of Breast and Axillary Lesions Technical and Clinical Aspects

    University dissertation from Uppsala : Institutionen för onkologi, radiologi och klinisk immunologi

    Author : Shahin Abdsaleh; Uppsala universitet.; [2006]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Automatic core needle biopsy; Semiautomatic core needle biopsy; Surgical specimen; Dynamic needle behavior; Hormone Receptors; Radiologisk forskning; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning;

    Abstract : The aims of this work were to image and analyze the needle behavior at automated core biopsy, to investigate the clinical utility of an alternative core biopsy technique using a semiautomated gun in breast and axillary lesions, and also to compare core biopsy with surgical specimens in malignant breast lesions regarding histologic features and hormone receptor expression.In two experimental studies, using butter and silicon phantoms, respectively, the needle pass was imaged and its dynamic behavior studied.

  2. 2. MRI Diagnosis of Intracranial Hemorrhage Experimental and Clinical Studies

    University dissertation from Uppsala : Institutionen för onkologi, radiologi och klinisk immunologi

    Author : Montserrat Alemany Ripoll; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; hemorrhage; experimental; MRI; T2*-w GE sequence; old microhemorrhages; stroke; Radiologisk forskning; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning; radiologi; Radiology;

    Abstract : The purpose of this work was to improve the diagnosis of intracranial hemorrhage with MRI, using, among others, T2*-w GE sequences. Various sequences were tested in rabbits at two magnetic field strengths. Then, the most effective technique was applied to stroke patients. READ MORE

  3. 3. Degradation, Metabolism and Relaxation Properties of Iron Oxide Particles for Magnetic Resonance Imaging

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Karen Briley Saebo; Uppsala universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Magnetic Resonance Imaging; contrast agents; iron oxide particles; metabolism; relaxation mechanisms; Radiologisk forskning; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning;

    Abstract : Whereas the effect of size and coating material on the pharmacokinetics and biodistribution of iron oxide based contrast agents are well documented, the effect of these parameters on liver metabolism has never been investigated. The primary purpose of this work was to evaluate the effect of iron oxide particle size and coating on the rate of liver clearance and particle degradation using a rat model. READ MORE

  4. 4. On Renal Artery Stenosis

    University dissertation from Uppsala : Enheten för radiologi

    Author : Hampus Eklöf; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Renal artery obstruction; Comparative studies; Contrast media; adverse events; Revascularization; Radiologisk forskning; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning;

    Abstract : Renal artery stenosis (RAS) is a potentially curable cause of hypertension and azotemia. Besides intra-arterial renal angiography there are several non-invasive techniques utilized to diagnose patients with suspicion of renal artery stenosis. READ MORE

  5. 5. The Utility of Manganese for Magnetic Resonance Imaging of Transient Myocardial Ischemia

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Rolf Eriksson; Uppsala universitet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Radiologisk forskning; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning; radiologi; Radiology;

    Abstract : In order to improve the diagnosis of coronary artery disease, better methods for detection of myocardial perfusion defects would be useful. One of the methods used for myocardial perfusion evaluation today is magnetic resonance imaging. READ MORE
