  1. 1. Fast Parametric Registration and Machine Learning Analysis of Whole-Body MRI Volumes for Age-Related Changes

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Saradh Tiwari; [2021]
    Keywords : ;

    Abstract : Using an extensive dataset provided by the UK Biobank, this project intended to develop methods for registering whole body MRI volumes and analyzing the changes in the body due to ageing. The registration method is developed using the pTV image registration module, which employs a fast registration approach based on parametric total-variation to align volumes to the same local coordinate frames of the reference, for point-wise anatomical region correspondence.

  3. 2. Deep Learning-Based Skeleton Segmentation for Analysis of Bone Marrow and Cortical Bone in Water-Fat Magnetic Resonance Imaging

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

    Author : Adham Belbaisi; [2021]
    Keywords : Water-fat MRI; UK Biobank; Deep learning; Skeleton segmentation; Bone marrow; Cortical bone;

    Abstract : A major health concern for subjects with diabetes is weaker bones and increased fracture risk. Current clinical assessment of the bone strength is performed by measuring Bone Mineral Density (BMD), where low BMD-values are associated with an increased risk of fracture. READ MORE

  4. 3. High-Performance Computing with Python in Whole-Body MRI Voxel-WiseStudies: An Im iomics study in associations with age.

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Brent Hetfye Sanchez; [2021]
    Keywords : ;

    Abstract : The Section of Radiology from the Department of Surgical Sciences at Uppsala University developed a technique to study whole-body MRI images in voxel-wise studies. Recently, they were granted access to a bio-bank of 40,000 neck-to-knee whole-body MRI images. These voxel-wise studies of large datasets demand large storage and computing resources. READ MORE

  5. 4. Similarity models for atlas-based segmentation of whole-body MRI volumes

    University essay from Linköpings universitet/Institutionen för medicinsk teknik

    Author : Elin Axberg; Ida Klerstad; [2020]
    Keywords : Atlas-based segmentation; image registration; image similarity measures;

    Abstract : In order to analyse body composition of MRI (Magnetic Resonance Imaging) volumes, atlas-based segmentation is often used to retrieve information from specific organs or anatomical regions. The method behind this technique is to use an already segmented image volume, an atlas, to segment a target image volume by registering the volumes to each other. READ MORE

  6. 5. Semi-automatic evaluation of lymph nodes in patients with rectal neoplasms with diffusion weighted MRI

    University essay from Lunds universitet/Sjukhusfysikerutbildningen; Lunds universitet/Medicinsk strålningsfysik, Lund

    Author : Daniel Roth; [2016]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and purpose Several studies have shown that surgery with pre- or post-operative adjuvant radiotherapy reduces the local recurrence rate in rectal cancer patients. Preoperative evaluation of lymph node involvement is difficult but important for assessing the benefit of radiotherapy. READ MORE
