  2. 1. 3D Rotational Angiography of Transplanted Renal Arteries : A Clinical and Experimental Study

    Author : Gaute Hagen; Anders Magnusson; Jonas Wadström; Jarl Jakobsen; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Ultrasonography of the urinary tract in children, with special emphasis on the urinary bladder

    Author : Lennart Müller; Göteborgs universitet; []
    Keywords : child; ultrasonography; bladder; detrusor; myelomeningocele; urinary tract infection; permanent renal damage;

    Abstract : Ultrasonography (US) is routinely used in children with urinary tract disorders. However, the bladder is usually evaluated with invasive methods, e.g. voiding cystourethrography (VCU) and cystometry. READ MORE

  5. 3. On Renal Artery Stenosis

    Author : Hampus Eklöf; Rickard Nyman; David Bergqvist; Bertil Andrén; Lars Lönn; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Renal artery obstruction; Comparative studies; Contrast media; adverse events; Revascularization; Radiologisk forskning; Radiological research; 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

  6. 4. Power Doppler - Principles and Potential Clinical Applications

    Author : Anders Nilsson; PG Lindgren; Torbjörn Andersson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Ultrasonography; Doppler studies; Power Doppler; Volume flow; Radiologisk forskning; Radiological research; Radiologisk forskning;

    Abstract : The purpose of this work was to: a) Determine whether the amount of colour in a power Doppler image is dependent on the angle between the examined vessel and the soundbeam and/or on the velocity of the flow within the vessel; b) Investigate if a dependency on flow velocity could be used for the detection of volume flow differences and c) Define clinical applications utilising the improved sensitivity to low flow of PD.In the experimental studies (study I and II) a silicon tube in a water bath was insonated, the insonation angle and the volume flow changed and the resulting images stored, transferred to a personal computer and analysed with regard to the amount of colour present in the image.

  7. 5. Maternal renal artery Doppler velocimetry in normal and hypertensive pregnancies

    Author : Marius Kublickas; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Atrial natriuretic factor Cyclicguanosine monophosphate Doppler ultrasoundKidney Modeling Preeclampsia Pregnancy Preg-nancy induced hypertension Pulsatility index Re-nal artery Renal blood flow Repeatability.Stockholm 1966;

    Abstract : Background: The measurement of effective renal plasma flow (ERPF) by calculation of p-aminohippurate (PAH) clearance is an invasive, time-consuming procedure. In nonpregnant humans, the clearance of isotopes can be used to measure renal plasma flow, but the use of these radioactive substances during pregnancy is unsuitable. READ MORE
