1. 1. Automation of Kidney Perfusion Analysis from Dynamic Phase-Contrast MRI using Deep Learning

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Andrés Martínez Mora; [2020]
   Keywords : Deep Learning; Segmentation; Kidney Imaging; MRI; Flow Analysis; Chronic Kidney Disease;

   Abstract : Renal phase-contrast magnetic resonance imaging (PC-MRI) is an MRI modality where the phase component of the MR signal is made sensitive to the velocity of water molecules in the kidneys. PC-MRI is able to assess the Renal Blood Flow (RBF), which is an important biomarker in the development of kidney disease. READ MORE

3. 2. Automatic Segmentation of Intracranial Arteries in 4-Dimensional Phase Contrast Magnetic Resonance Angiography

   University essay from Institutionen för fysik

   Author : Erik Spaak; [2013]
   Keywords : ;

   Abstract : The development of a highly effective phase-contrast magnetic resonance imag- ing (PC-MRI) technique named phase-contrast vastly undersampled isotropic projection reconstruction (PC-VIPR) has improved the ability to image blood flow in the brain. The technique allows for the acquisition of temporally resolved volume images with high spatial resolution. READ MORE

4. 3. Segmentation of the cardiovascular tree in 4D from PC-MRI images

   University essay from Lunds universitet/Matematik LTH

   Author : Peter Öberg; [2013]
   Keywords : Fourflow; Segment flow; PC-MRI; visualization; 4D; flow; Cardiovascular tree; noise reduction; Mathematics and Statistics; Medicine and Health Sciences;

   Abstract : Investigating the dynamics of blood flow is essential to understanding the cardiovascular system and its pathologies. Phase Contrast Magnetic Resonance Imaging (PC-MRI) enables acquisition of 4-dimensional time resolved velocity experiments. Slice-by-slice analysis of the data is time consuming and cumbersome.

5. 4. Estimation and visualization of relative pressure fields in the human heart from time resolved MRI flow data

   University essay from Institutionen för medicinsk teknik; Centrum för medicinsk bildvetenskap och visualisering, CMIV; Tekniska högskolan

   Author : Emre Kus; [2013]
   Keywords : phase contrast; MRI; cardiac pressure; blood flow; medical imaging;

   Abstract : Heart diseases are the leading cause of death in developed countries, hence, understanding of the hemodynamics of the heart is critically important to enable methods for cardiovascular diagnosis. Assessment of intracardiac blood pressure is highly interesting as blood flow is driven by the pressure differences. READ MORE

6. 5. Simulation of Phase Contrast MRI Measurements from Numerical Flow Data

   University essay from Institutionen för medicinsk teknik; Tekniska högskolan

   Author : Sven Petersson; [2008]
   Keywords : MRI; phase contrast; blood flow; simulation; stenosis; CFD; wall shear stress; turbulence;

   Abstract : Phase-contrast magnetic resonance imaging (PC-MRI) is a powerful tool for measuring blood flow and has a wide range of cardiovascular applications. Simulation of PC-MRI from numerical flow data would be useful for addressing the data quality of PC-MRI measurements and to study and understand different artifacts. READ MORE
