1. 1. Phase Unwrapping MRI Flow Measurements

   University essay from Uppsala universitet/Avdelningen Vi3

   Author : Mio Liljeblad; [2023]
   Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

   Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

3. 2. Comparison of direct Fick's principle and thermodilution for calculating cardiac output in patients with pulmonary arterial hypertension.Does the assessment of cardiac index and pulmonary vascular resistance differ depending on which method is chosen?

   University essay from Örebro universitet/Institutionen för hälsovetenskaper

   Author : Gabriella Persson; [2023]
   Keywords : Pulmonary arterial hypertension; cardiac output; direct Fick´s principle; thermodilution;

   Abstract : Pulmonary arterial hypertension (PAH) is an uncommon but serious disease that causes increased pressure in the pulmonary vessels and increased pulmonary vascular resistance (PVR), which in turn leads to right heart failure. At diagnosis, mean pulmonary artery pressure (mPAP) must be >20 mmHg, pulmonary artery wedge pressure (PAWP) ≤15 mmHg and PVR >2 Wood units (WU). READ MORE

4. 3. Pulmonary Response During Exercise: an Invasive Study on Mean Pulmonary Artery Pressure in Relation to Cardiac Output

   University essay from Örebro universitet/Institutionen för hälsovetenskaper

   Abstract : .... READ MORE

5. 4. Assessment of hemodynamic parameters using 4D Flow MRI

   University essay from Lunds universitet/Matematik LTH

   Author : Mattias Andersson; [2018]
   Keywords : Hemodynamics; Hemodynamic Parameters; 4D Flow; 4D Flow MRI; Blood flow; Cardiac Disease; Heart Disease; MRI; Magnetic Resonance Imaging; Visualisation; Mathematics and Statistics;

   Abstract : Heart disease is one of the worldwide leading causes of death, and facilitating the work of physicians in this area is therefore of great importance. Imaging of the heart is one of many fields that is used for diagnosis and analysis of cardiac disease. READ MORE

6. 5. Testing of micro-fluidic systems for Raman spectroscopic measurements on biological cells

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Malin Berger; [2018]
   Keywords : ;

   Abstract : Pulmonary Artery Hypertension (PAH) is a condition that can affect people as a consequence of infections or diseases such as lung disease, high blood pressure or pneumonia. When afflicted by these diseases, low oxygen content in the lung tissue causes the pulmonary arterial soft muscle cells (PASMC) located in the walls of the pulmonary arteries to chronically swell up.
