  1. 1. Identifying Graph Characteristics in Growing Vascular Networks

    University essay from Uppsala universitet/Tillämpad beräkningsvetenskap

    Author : Christopher Finn Plummer; [2024]
    Keywords : Anigogenesis; Vascular Networks; Network Science;

    Abstract : One of the ways that a vascular network grows is through the process of angiogenesis, wherebya new blood vessel forms as a branch from an existing vessel towards an area which isstimulating vascular growth. Due to the demands for nutrients and waste transport, growingtumour cells will access the surrounding vascular network by inducing angiogenesis. READ MORE

  3. 2. Network Orientation and Segmentation Refinement Using Machine Learning

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Michael Nilsson; Jonatan Kentson; [2023]
    Keywords : deep learning; semantic segmentation; orientation learning; road networks; retina networks;

    Abstract : Network mapping is used to extract the coordinates of a network's components in an image. Furthermore, machine learning algorithms have demonstrated their efficacy in advancing the field of network mapping across various domains, including mapping of road networks and blood vessel networks.

  4. 3. A CNN-based Analysis of Radiological Parameters from CT images : Improving Surgical Outcomes in Soft Tissue Sarcoma Patients with Pulmonary Metastases

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Klara Solander; [2023]
    Keywords : CNN; Convolutional Neural Network; AI; Artificial Intelligence; CT; STS; Soft Tissue Sarcoma; PM; Pulmonary Metastases;

    Abstract : Soft tissue sarcoma (STS) patients with pulmonary metastases (PM) experience a significant decrease in 5-year survival rates, ranging from 15 % to 50 % compared to 81 % without metastases. Despite this clinical challenge, there is a lack of consensus regarding the optimal treatment approach for PM in STS. READ MORE

  5. 4. Development of a tool for analysis and visualization of longitudinal magnetic resonance flowmeasurements : of subarachnoid hemorrhage patients in the neurointensivecare unit

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : ILDI ADOK; [2023]
    Keywords : 2D phase contrast MRI; subarachnoid hemorrhage; cerebral blood flow; visualization; neurointensive care;

    Abstract : Patients who are treated in an intensive care unit need continuous monitoring in orderfor clinicians to be prepared to intervene should a secondary event occur. For patientstreated at the neurointensive care unit (NICU) who have suffered a subarachnoid hemorrhage (SAH) this secondary event could be ischemia, resulting in a lack of blood flow. READ MORE

  6. 5. Sex-specific pathological response to Traumatic Brain Injury

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Christopher Fry; [2022]
    Keywords : Biology and Life Sciences;

    Abstract : Traumatic brain injury (TBI) is one of leading causes of death in the world; survivors commonly exhibit behavioural changes and neurocognitive defects in the long-term. Following TBI, rapid changes in the neurovascular unit (NVU) occur as the permeability of the blood brain barrier (BBB) increases and cerebral blood flow (CBF) becomes dysregulated. READ MORE
