1. 1. 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

3. 2. Automatic 3D Segmentation in CT images of Congenital Heart Defects using Deep Learning

   University essay from Lunds universitet/Matematik LTH

   Author : Matilda Dahlström; [2022]
   Keywords : Technology and Engineering;

   Abstract : 3D segmentations of hearts with congenital heart defects are routinely used today. They are used to study hearts and to prepare before surgery which makes them an important part of patient care. The 3D segmentations are usually created manually, which is a time-consuming process.

4. 3. Förändringar i vilo-EKG hos hästar med dynamiska obstruktioner i de övre luftvägarna

   University essay from SLU/Dept. of Clinical Sciences

   Author : Maria Neil; [2022]
   Keywords : DDSP; felläge av mjuka gommen; upprättstående struplock; stämbandsförlamning; gomsegelhöjning; T-vågor; ventrikulära arytmier; endoskopi;

   Abstract : Hästar med övre luftvägsobstruktioner har visat sig vara predisponerade för utvecklingen av arytmier. Även om dessa är relativt vanligt förekommande i återhämtningsfasen är en ökad förekomst alarmerande då ventrikulära arytmier tros vara den vanligaste anledningen till de plötsliga dödsfall som sker på banorna.

5. 4. Semi-Automatic Analysis and Visualization of Cardiac 4D Flow CT

   University essay from Linköpings universitet/Institutionen för hälsa, medicin och vård

   Author : Anthony van Oosten; [2022]
   Keywords : 4D CT; CT; 4D flow; Flow Component Analysis; Singular value decomposition; left atrial appendage; LAA; CFD; 3 chamber view; computed tomography; maximum outflow velocity; volume rendered CT; semi-automatic; visualization; flow visualization; cardiac views; semi-automatic analysis; semi-automatic visualization; visualization of 4D flow;

   Abstract : The data obtained from computational fluid dynamics (CFD) simulations of blood flow in the heart is plentiful, and processing this data takes time and the procedure for that is not straightforward. This project aims to develop a tool that can semi-automatically process CFD simulation data, which is based on 4D flow computed tomography (CT) data, with minimal user input. READ MORE

6. 5. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments

   University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologi

   Author : Amanda Eriksson; [2021]
   Keywords : Cerebral Blood Flow; CBF; oxygen-15-labelled water; PET CT; PET MR; Quantification of CBF; Image Derived Input Function; IDIF; Blood Sampled Input Function; BSIF; Arterial Input Function; AIF; Tracer Kinetic Modelling; Single Tissue Compartmental Model; 1TCM;

   Abstract : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. READ MORE
